In order to run jobs on Trixie, users need to specify which SLURM Account Code should be used for billing. This is handled by adding a line in the SLURM submission script which identifies the account

+
SBATCH --account=account_code
+
+

Users must be authorized to charge an account before they can use it.

How to I get my job to requeue after my time limit?

+

Here’s a skeleton of what our jobs look like. Please check your job once it is running to dial down the number of cpus and memory needed. If we don’t use the node’s full resources, it would be nice to be able to submit other cpu-only jobs, aka none gpu jobs on those nodes.

+

Important steps in order to get automatic requeueing working: +* Ask slurm to send you a signal 30 seconds before the end of your time limit --signal=B:USR1@30 +* Have a thread listen to the requested signal trap _requeue USR1 +* Send your MAIN process in the background and wait for it otherwise your _requeue function will NEVER get a chance to run.

The most up-to-date way to see which software has been preinstalled on Trixie is by using the module command. When in double, it is the definitive list.

+

Software on Trixie is organized using the module service. Users can load, unload, and swap libraries within their environment and job submission scripts via modules.

+

If there is a piece of software you would like to use but it is not available from the list (and you can't figure out how to build it yourself in your home directory), you may create a request using the issues tab (https://github.com/ai4d-iasc/trixie/issues). Please do not create duplicate requests for software (but feel free to comment on a thread to ''upvote'' the priority list is clear.

+ /gpfs/work/${USER} will be the primary + work-space for users and will have a quota of 500GB and 1M inodes + with snapshots enabled +

+ +

+ We request that users not create conda, mamba, venvs, etc + within the /gpfs/work space, and instead use their /home and create symlinks to + their projects. The snapshot feature of GPFS does not perform + optimally when many small files are created and destroyed as with + such utilities.

Overview

+

To ease usage of the bastion host to easily connect to Trixie, there are some steps which can be taken, especially making use of the SSH ProxyJump and ControlMaster parameters. Basically, you need to configure SSH to automatically connect with the Trixie server using the bastion host as a connector between your local computer and the Trixie server.

+

Important Note: Before proceeding with this configuration, please ensure that you have performed the External Access Setup procedure.

+

Mac OSX / Linux

+

To configure SSH to automatically connect to the Trixie server, please open your .ssh/config file with your preferred text editor and add the following lines on your local machine – not the servers – while substituting your given usernames in the User directive. You will also need to create the folder .ssh/sockets to complete the configuration.

+
Host trixie-bastion
+  HostName trixie.nrc-cnrc.gc.ca
+  User <firstname>.<lastname>@pub.nrc-cnrc.gc.ca 
+  ControlMaster auto
+  ControlPath ~/.ssh/sockets/%r@%h-%p
+
+Host trixie
+  HostName trixie.res.nrc.gc.ca 
+  User admin.<firstname>.<lastname>
+  ProxyJump trixie-bastion
+
+

Once your settings are configured, you will be able to login to the Trixie server with the following command

+

ssh trixie

+

Please note that you will be prompted as follows

+
    +
  1. LoginTC prompt – enter 1
    2. +
  2. Prompt for your PUB password
    3. +
  3. Prompt for your RES admin password
    4. +
+

Windows – Putty

+

To configure SSH to automatically connect to the Trixie server, please set the following settings in your Putty application, substituting your username where applicable.

+
    +
  1. +

    Under Connection -> SSH

    +
      +
    1. Set Remote command: ssh –A –Y admin.<firstname>.<lastname>@trixie.res.nrc.gc.ca
      2. +
    2. Select the option Share SSH connections if possible – this will enable you to establish multiple connections to Trixie
      3. +
    +

    trixie putty
    +2. Under Connection -> SSH -> X11

    +
      +
    1. Select the option Enable X11 forwarding
      2. +
    +

    putty
    +3. Under Session

    +
      +
    1. Set Host Name (or IP address): <span>@pub.nrc-cnrc.gc.ca <span>@trixie.nrc-cnrc.gc.ca
      2. +
    2. Set Port: 22
      3. +
    3. Add a name for Saved Sessions – perhaps Trixie
      4. +
    +

    putty
    +4. Click Save

    +
    2. +
+

Once the settings have been saved, you can double click on the name in the list of Saved Sessions to open a session to the Trixie server. Please note that you will be prompted as follows

+
    +
  1. LoginTC prompt – enter 1
    2. +
  2. Prompt for your PUB password
    3. +
  3. Prompt for your RES admin password
    4. +
+

Overview

+

As an external NRC collaborator, you can access the AI for Design (Trixie) Cluster using the Bastion Host. External collaborators include non-NRC researchers, industrial partners, and vendors.

+

You can access only those folders on Trixie that are required for your project. Requests for access to Trixie and specific projects must be made by your NRC research contact; you cannot request access to a system yourself.

+

Once granted access, you will have two sets of credentials issued to access the cluster:

+ + + + + + + + + + + + + + + + + + + + +
AccountPurposeUser name format (example: John Doe)
PUBProvides access to the external bastion host and used for theLoginTC second factor authenticationA combination of your first and last name. E.g.: john.doe@pub.nrc-cnrc.gc.ca
Trixie SystemProvides access to Trixieadmin.firstname.lastname E.g.: admin.john.doe
+

Your NRC contact, or an NRC system administrator, will provide you with the PUB and Admin user names and passwords that you require to access the NRC systems. Note that on first login, you will be required to change your password. Please note: during the password change, the first prompt asks for a confirmation of your existing password prior to requesting a new one.

+

LoginTC Application Setup

+

Before you attempt your first login, the following initial installation and configuration of LoginTC must be implemented.

+
    +
  • Upon user creation, you will receive an email to setup and initialize the LoginTC application (for iOS, Android, or the Chrome web browser) which is used as a second factor authentication into Trixie
    • +
  • Set up LoginTC using the directions provided to you by email
    • +
+

Accessing Trixie with LoginTC 2-Factor Authentication

+

In order to access Trixie, you will need to use an SSH client. Please note that you cannot access Trixie using a web browser. On Mac OSX and Linux, SSH is installed by default. On Windows you will need to install Putty if it is not installed already. You can download Putty from the following website:

+

https://www.putty.org/

+

Initialize SSH Connection with Mac OSX / Linux

+

For Mac OSX and Linux you can open a new terminal and connect to trixie.nrc-cnrc.gc.ca via ssh using your PUB account and the following command

+

ssh <firstname.lastname>@pub.nrc-cnrc.gc.ca trixie.nrc-cnrc.gc.ca

+

Initialize SSH Connection with Windows

+

For Windows, you can create a Putty profile to SSH into the bastion server

+

Under Session

+
    +
  1. Set Host Name (or IP address): <span>@pub.nrc-cnrc.gc.ca <span>@trixie.nrc-cnrc.gc.ca
    2. +
  2. Set Port: 22
    3. +
  3. Add a name for Saved Sessions – perhaps Bastion
    4. +
+

img
+4. Click Save

+

Once the settings have been saved, you can double click on the name in the list of Saved Sessions to open a session to the bastion server.

When you login for the first time you will be forced to change your password for both your Pub account and your Trixie admin account. Please note that when you do this, you will be prompted for your original (or current) password first and then you will be prompted to enter your new password twice.

+

In the following procedure, the information printed in the images may not be the same as what you will see when you login. However the steps will be the same.

+

Please perform the following steps to access Trixie.

+
    +
  1. When you login using one of the methods above, you will be prompted to authenticate with your LoginTC application. The message should appear as follows:
    2. +
+

putty +2. Press 1 followed by the Enter key and then check your LoginTC device as setup above to approve the login request +3. If a message similar to the one below appears, then simply type in yes to the prompt as shown below

+

login +4. After you complete the two-factor authentication process in LoginTC you will be prompted to enter your PUB account password and then you will be forced to change your password. You should see a message similar to the one below – remember to enter your original password first and then enter your new password twice.

+

login3 +5. The system will automatically log you out, thus, you will need to login again using your new password +6. Once you have successfully logged in, you will be logged into the bastion server – your screen should look similar to the following

+

login4 +7. If you have your credentials for the trixie.res.nrc.gc.ca server you can skip this step. Otherwise, you will now need to contact the administrator who provided you with your credentials for the bastion server to obtain your credentials for the Trixie server +8. You will need to login to Trixie next. From the bash prompt, use SSH to log into trixie.res.nrc.gc.ca with your Trixie admin. account and password with a similar command as the following.

+

ssh admin.<firstname.lastname>@trixie.res.nrc.gc.ca +9. If a message similar to the one below appears, then simply type in yes to the prompt as shown below

+

login2 +10. You will be prompted to enter your Trixie admin account password and then you will be forced to change your password. You should see a message similar to the one below – remember to enter your original password first and then enter your new password twice.

+
![images/login3.png](images/login3.png)
+
+
    +
  1. The system will automatically log you out, thus, you will need to login again using your new password
    2. +
  2. +

    Once you have successfully logged in, you will be logged into Trixie – your screen should look similar to the following

    +

    login5

    +
    3. +
+

After successful authentication, you should see the Trixie cluster login banner with terms and be placed in a shell in your home directory on the cluster, similar to the image above.

+

Note that you will be placed in your home directory which only you have access to. For more information on the cluster and its usage, please see the:

+

Home

+

Changing passwords

+

Passwords on the PUB and RES accounts expire after 90 days and must be changed. If you do not change your password, you will be locked out of the system.

+

Watch for the pop-up message notifying you to change your password, or set yourself a reminder to change your password before the 90-day expiry.

+

If you get locked out of your account due to an expired password for any account, notify your NRC contact who can have the password reset.

+

Change Your PUB Password

+

You can change your PUB password by logging into the following website. The site allows you to manage your PUB account. Please use the following format for your username john.doe@pub

+

PUB Account Management

+

Please note that the Reset Password feature will not work if you do not fill in the security questions on the website. Therefore it is strongly recommended that you fill in the security questions so that you can reset your password if necessary.

+

Change Your Admin Password via Linux Terminal

+
    +
  1. Ensure you are logged into the Trixie server (trixie.res.nrc.gc.ca)
    2. +
  2. Type passwd then hit Enter
    3. +
  3. You will be prompted for your original (or current) password first and then you will be prompted to enter your new password twice. You should see a message similar to the one below – remember to enter your original password first and then enter your new password twice.
    4. +
+

Overview

+

There may be instances where researchers require connectivity to external HPC systems from Trixie. However, network access to and from Trixie is restricted to maintain a high level of security. Therefore, connections to external systems need to be approved before the connection can be opened.

+

This page provides instructions for requesting a connection to an external system, as well as a list of approved systems that already have an open connection.

+

Request a Connection to an External System

+

In order to submit a request to open a network flow between Trixie and an external HPC system, please post your request in the issues section of this site.

Overview

+

This document will describe various procedures for transferring files to and from Trixie.

+

Important Note: For external users, before proceeding with this configuration, please ensure that you have performed the external access setup and advanced configuration procedures.

+

Transfers Between Your Local Computer and Trixie

+

The following sections detail how to transfer files between your local computer and Trixie. They basically rely on advanced SSH configurations to bridge the network between your local computer and Trixie.

+

Mac OSX / Linux

+

To copy a file to the Trixie server, please use the scp command on your local machine.

+

External Users

+

Please note that the use of this method requires that your system be configured as detailed in the advanced configuration in order to provide a direct link between your local machine and the Trixie server.

+

The following command will copy the file test.txt from John Doe’s local machine to his admin.john.doe account on Trixie. Please note that using trixie as the hostname will only work if you have configured SSH to use ProxyJump as detailed in the advanced configuration.

+

scp test.txt trixie:/home/admin.john.doe

+

To copy a file from Trixie to your local machine, you basically reverse the arguments to the scp command.

+

scp trixie:/home/admin.john.doe/test.txt test.txt

+

To copy an entire directory instead of just a file, please use the –r option (for recursive) to the scp command.

+

scp –r myWorkFilesDir trixie:/home/admin.john.doe

+

Internal Users

+

The following command will copy the file test.txt from John Doe’s local machine to his account on Trixie. Please note that the example assumes the username on Trixie is different than the username on the local machine.

+

scp test.txt doej@trixie.res.nrc.gc.ca:/home/doej

+

To copy a file from Trixie to your local machine, you basically reverse the arguments to the scp command.

+

scp doej@trixie.res.nrc.gc.ca:/home/doej/test.txt test.txt

+

To copy an entire directory instead of just a file, please use the –r option (for recursive) to the scp command.

+

scp –r myWorkFilesDir doej@trixie.res.nrc.gc.ca:/home/doej

+

Windows Using the pscp Command From Putty

+

To copy a file to the Trixie server, please use the pscp command on your local machine.

+

External Users - this process does not work at the moment

+

Please note that the use of this method requires that you have two Putty profiles defined.

+
    +
  1. A profile for the bastion server
    2. +
  2. A profile for the Trixie server
    3. +
+

Bastion Server Profile

+

The bastion server profile was likely created during the setup configuration for your external access to Trixie. If not, then please see the initialize SSH connection section for detailed instructions on creating a profile for the bastion server.

+

Trixie Server Profile

+

Follow the procedure below to create the Trixie server profile.

    +
    4. +
+

Transfers Between Trixie and Another HPC Cluster

+

Needs verification that this is accurate and works, as well as real parameters for the command lines please

+

The procedures in this section assume that the advanced SSH configurations discussed above have been implemented. There are three options for copying files between Trixie and another HPC cluster

+
    +
  1. Copy files directly between Trixie and the HPC cluster
    2. +
  2. Login to Trixie from the other HPC cluster
    3. +
  3. Copy files through your local computer
    4. +
+

Copy Files Directly

+

This procedure requires that there is an approved network flow open between Trixie and the second HPC cluster. Please see the external HPC systems page for a list of approved external HPC systems. If there is an approved network flow, then files can be directly copied between Trixie and the second HPC cluster. This is the ideal situation and should be the fastest option in terms of overall network speed between the two systems.

+

To copy a file from the second HPC cluster to Trixie, use the following scp command on the Trixie server.

+

scp username@cluster.domain:/home/username/test.txt test.txt

+

To copy a file from Trixie to the second HPC cluster, you basically reverse the arguments to the scp command.

+

scp test.txt username@cluster.domain:/home/username/test.txt

+

To copy an entire directory instead of just a file, please use the –r option (for recursive) to the scp command.

+

scp –r myWorkFilesDir username@cluster.domain:/home/username/folder

+

Login to Trixie From Second Cluster

+

This procedure requires that you have an external account setup to access Trixie. If this is the case, then files can be copied between Trixie and the second HPC cluster via the Bastion Host, but without flowing through your local computer. To use this approach, you will need to login to the second HPC cluster first, and then from the second HPC cluster computer, login to Trixie through the Bastion host.

+

To copy a file from the second HPC cluster to Trixie, use the following scp command on the Trixie server.

+

scp username@cluster.domain:/home/username/test.txt test.txt

+

To copy a file from Trixie to the second HPC cluster, you basically reverse the arguments to the scp command.

+

scp test.txt username@cluster.domain:/home/username/test.txt

+

To copy an entire directory instead of just a file, please use the –r option (for recursive) to the scp command.

+

scp –r myWorkFilesDir username@cluster.domain:/home/username/folder

+

Copy Files Through Your Local Computer

+

This procedure requires that you copy files between the two clusters using your local computer as a bridge. The commands below should be executed on your local computer and not either of the cluster servers.

+

To copy a file from the second HPC cluster to Trixie, use the following scp command on your local computer.

+

scp username@cluster.domain:/home/username/test.txt trixie:/home/admin.john.doe/test.txt

+

To copy a file from Trixie to the second HPC cluster, you basically reverse the arguments to the scp command.

+

scp trixie:/home/admion.john.doe/test.txt username@cluster.domain:/home/username/test.txt

+

To copy an entire directory instead of just a file, please use the –r option (for recursive) to the scp command.

+

scp –r trixie:/home/admin.john.doe/myWorkFilesDir username@cluster.domain:/home/username/folder

+

Copy Files to a Project Folder

+

Project folders have been created for users to use for a couple of purposes:

+
    +
  1. Storage of data files to use with Trixie. Although you can use your home directory for limited storage of files, it is strongly recommended that you use the project folder instead as there are higher disk quotas for project folders.
    2. +
  2. Sharing of project work and files with team members
    3. +
+

Please note that users should be diligent and remove any files and folders (in both the project folder and your home folder) once they are no longer required. This helps to optimize disk usage and avoid disk space issues for all users, not just your own usage.

+

The project folder can be found under the following folder hierarchy

+

/gpfs/projects/<project-group>/<project>

+

Where project-group is the name of your project group – for example, AI4D or COVID - and project is the name of your project – for example, core-01 or bio-01.

+

To copy files to a project folder you should create a personal folder under the project directory and then copy files from your home directory to the new folder. In the example below user John Doe will copy two dataset files to the AI4D/bio-01 project folder.

+
    +
  1. Change directory to the project folder
    2. +
+

cd /gpfs/projects/AI4D/bio-01 +2. Create the new folder using a unique name, perhaps your last name and first initial

+

mkdir doej +3. Change back to your home directory

+

cd +4. Copy the files to your new project directory

+

cp dataset1.dat dataset2.dat /gpfs/projects/AI4D/bio-01/doej

+

This examples will show you how to setup and prepare an environment for PyTorch jobs using conda on Trixie:

+

1. Create a pytorch miniconda environment:

+

Either run from the command line or create pytorchconda-environment.sh and run it:

+
#!/bin/bash
+# load the miniconda module
+module load miniconda3-4.8.2-gcc-9.2.0-sbqd2xu
+# create a conda environment with python 3.7 named pytorch
+conda create --name pytorch python=3.7
+source activate pytorch
+# install pytorch dependencies via conda
+conda install pytorch==1.7.1 torchvision==0.8.2 cudatoolkit=10.1 -c pytorch
+
+

2. Create a test pytorch python script: testtorch.py

+
import torch
+print('GPU available:', torch.cuda.is_available())
+
+

3. Create a job submission script: testpytorch.sh

+
#!/bin/bash
+
+# Specify the partition of the cluster to run on (Typically TrixieMain)
+#SBATCH --partition=TrixieMain
+# Add your project account code using -A or --account
+#SBATCH --account ai4d
+# Specify the time allocated to the job. Max 12 hours on TrixieMain queue.
+#SBATCH --time=12:00:00
+# Request GPUs for the job. In this case 4 GPUs
+#SBATCH --gres=gpu:4
+# Print out the hostname that the jobs is running on
+hostname
+# Run nvidia-smi to ensure that the job sees the GPUs
+/usr/bin/nvidia-smi
+
+# Load the miniconda module on the compute node
+module load miniconda3-4.8.2-gcc-9.2.0-sbqd2xu
+# Activate the conda pytorch environment created in step 1
+source activate pytorch
+# Launch our test pytorch python file
+python testtorch.py
+
+

4. Submit job for execution:

+
sbatch testpytorch.sh

Quickstart

+ +

Trixie use the slurm scheduler to manage jobs. +Compute Canada has a very good guide for using slurm to submit jobs to a cluster most of which is applicable for Trixie: https://docs.computecanada.ca/wiki/Running_jobs

+

Here is a simple job which runs the python code hello.py

+

Contents of hello.py

+
print('Hello world')
+
+

Contents of hello-job.sh

+
#!/bin/bash
+#SBATCH -J helloworld
+
+module load miniconda3-4.8.2-gcc-9.2.0-sbqd2xu
+srun python ~/hello.py
+
+

Submit job:

+
sbatch ./hello-job.sh
+
+

Output will be located in slurm-<jobid>.out

+

In order for a job to run on Trixie, it must be "billed" against an approved project. Users are able to charge different projects depending on what their activity is for.

+

See here for the Account Codes

Overview

+

It is possible to retrieve data from automatically generated filesystem backups. The IBM Spectrum Scale (GPFS) system includes the ability to create filesystem snapshots which create temporary backups of data stored in the filesystem. These snapshots can be accessed to retrieve files that may have been accidentally removed.

+

Please see the GPFS Snapshot document for more details on how to retrieve files from the backups.

    • +
  • [RESOLVED] - Monday April 11 - Wednesday April 13, 2022 (3 days) Please note that Trixie (AI4D HPC cluster) will be unavailable from April 11-13th (3 days) due to a scheduled upgrade. The GPFS file system will be upgraded during this time. If you have any questions or concerns about this maintenance please send an email to ITOperations-OperationsTI@nrc-cnrc.gc.ca. Update - Thursday April 14, 2022: Due to complications with the upgrade of the storage array the scheduled downtime for the AI4D-Trixie cluster has been extended. There is currently no estimate for when the cluster will return to service but an update will be sent out as soon as there is more information. - Update - Tuesday April 19, 2022 We are returning the AI4D-Trixie cluster to operational status. Unfortunately the storage array is in a degraded state and is only operating with 25% of its normal transfer capacity. Expect to see slowness from i/o intensive operations. All of the Compute Nodes as well as the Head Node have been re-imaged. The default operating environment has changed so expect many versions of the software loaded when you login to have changed. This may cause issues with job scripts created for the previous environment. If you experience any issues please let us know (ITOperations-OperationsTI@nrc-cnrc.gc.ca).
    • +
  • [RESOLVED] - Tuesday January 25, 2022 - There appears to be several issues with the Trixie HPC that are impacting access through the Bastion Host and general performance on the headnode. KITS-ITOps is investigating and hopes to resolve the issues as soon as possible. We will provide an update when we have more information. Update - There is a technical issue with the SSC managed switch due to a recent power outage. Access from Legacy and RES should still function but external access through the Bastion Host is not working. An SSC technician is supposed to be on site tomorrow morning to investigate.
    • +
  • [RESOLVED] - Wednesday December 15, 2021 - External access to Trixie is not available. It appears that there is an error with the SSL cert for the external LoginTC URL.

  • [RESOLVED - downtime completed successfully] - Monday August 23, 2021 - There will be a maintenance period for the Trixe AI4D Cluster on Monday August 23rd starting at 8:00 am EDT. Access to the cluster will not be possible during the maintenance. The entire day will be reserved for the maintenance but current estimates suggest it will be returned to service by noon. Maintenance will involve the replacement of a power distribution unit in one of the racks as well as configuration changes on the primary head node. Every effort will be made to preserve the job queue during the maintenance.
    • +
  • [RESOLVED - downtime completed successfully] - We are planning a period of scheduled downtime for the Trixie-AI4D cluster on Monday June 28th from 8:00am to 4:00pm EDT. This will allow a few maintenance tasks to be performed that would interrupt service. These tasks include modifying the partition structure on the primary head node as well as some security patching. - It has become necessary to add a firmware update to this maintenance window for the Mellanox switches. This will cause the GPFS file system to become unavailable forcing us to shutdown the cluster entirely. All jobs in the queue at the start of the maintenance period will likely be lost. - Due to unforeseen complications the maintenance period must be extended.
    • +
  • [RESOLVED - downtime completed successfully] - A period of downtime for the Trixie (AI4D) cluster is being scheduled for Monday, May 17th from 8:00 am - 6:00 pm EDT.

It\n * might be for example a function that you passed to Observable's constructor, but most of the time it is\n * a library implementation, which defines what will be emitted by an Observable, and when it be will emitted. This means\n * that calling `subscribe` is actually the moment when Observable starts its work, not when it is created, as it is often\n * the thought.\n *\n * Apart from starting the execution of an Observable, this method allows you to listen for values\n * that an Observable emits, as well as for when it completes or errors. You can achieve this in two\n * of the following ways.\n *\n * The first way is creating an object that implements {@link Observer} interface. It should have methods\n * defined by that interface, but note that it should be just a regular JavaScript object, which you can create\n * yourself in any way you want (ES6 class, classic function constructor, object literal etc.). In particular, do\n * not attempt to use any RxJS implementation details to create Observers - you don't need them. Remember also\n * that your object does not have to implement all methods. If you find yourself creating a method that doesn't\n * do anything, you can simply omit it. Note however, if the `error` method is not provided and an error happens,\n * it will be thrown asynchronously. Errors thrown asynchronously cannot be caught using `try`/`catch`. Instead,\n * use the {@link onUnhandledError} configuration option or use a runtime handler (like `window.onerror` or\n * `process.on('error)`) to be notified of unhandled errors. Because of this, it's recommended that you provide\n * an `error` method to avoid missing thrown errors.\n *\n * The second way is to give up on Observer object altogether and simply provide callback functions in place of its methods.\n * This means you can provide three functions as arguments to `subscribe`, where the first function is equivalent\n * of a `next` method, the second of an `error` method and the third of a `complete` method. Just as in case of an Observer,\n * if you do not need to listen for something, you can omit a function by passing `undefined` or `null`,\n * since `subscribe` recognizes these functions by where they were placed in function call. When it comes\n * to the `error` function, as with an Observer, if not provided, errors emitted by an Observable will be thrown asynchronously.\n *\n * You can, however, subscribe with no parameters at all. This may be the case where you're not interested in terminal events\n * and you also handled emissions internally by using operators (e.g. using `tap`).\n *\n * Whichever style of calling `subscribe` you use, in both cases it returns a Subscription object.\n * This object allows you to call `unsubscribe` on it, which in turn will stop the work that an Observable does and will clean\n * up all resources that an Observable used. Note that cancelling a subscription will not call `complete` callback\n * provided to `subscribe` function, which is reserved for a regular completion signal that comes from an Observable.\n *\n * Remember that callbacks provided to `subscribe` are not guaranteed to be called asynchronously.\n * It is an Observable itself that decides when these functions will be called. For example {@link of}\n * by default emits all its values synchronously. Always check documentation for how given Observable\n * will behave when subscribed and if its default behavior can be modified with a `scheduler`.\n *\n * #### Examples\n *\n * Subscribe with an {@link guide/observer Observer}\n *\n * ```ts\n * import { of } from 'rxjs';\n *\n * const sumObserver = {\n * sum: 0,\n * next(value) {\n * console.log('Adding: ' + value);\n * this.sum = this.sum + value;\n * },\n * error() {\n * // We actually could just remove this method,\n * // since we do not really care about errors right now.\n * },\n * complete() {\n * console.log('Sum equals: ' + this.sum);\n * }\n * };\n *\n * of(1, 2, 3) // Synchronously emits 1, 2, 3 and then completes.\n * .subscribe(sumObserver);\n *\n * // Logs:\n * // 'Adding: 1'\n * // 'Adding: 2'\n * // 'Adding: 3'\n * // 'Sum equals: 6'\n * ```\n *\n * Subscribe with functions ({@link deprecations/subscribe-arguments deprecated})\n *\n * ```ts\n * import { of } from 'rxjs'\n *\n * let sum = 0;\n *\n * of(1, 2, 3).subscribe(\n * value => {\n * console.log('Adding: ' + value);\n * sum = sum + value;\n * },\n * undefined,\n * () => console.log('Sum equals: ' + sum)\n * );\n *\n * // Logs:\n * // 'Adding: 1'\n * // 'Adding: 2'\n * // 'Adding: 3'\n * // 'Sum equals: 6'\n * ```\n *\n * Cancel a subscription\n *\n * ```ts\n * import { interval } from 'rxjs';\n *\n * const subscription = interval(1000).subscribe({\n * next(num) {\n * console.log(num)\n * },\n * complete() {\n * // Will not be called, even when cancelling subscription.\n * console.log('completed!');\n * }\n * });\n *\n * setTimeout(() => {\n * subscription.unsubscribe();\n * console.log('unsubscribed!');\n * }, 2500);\n *\n * // Logs:\n * // 0 after 1s\n * // 1 after 2s\n * // 'unsubscribed!' after 2.5s\n * ```\n *\n * @param {Observer|Function} observerOrNext (optional) Either an observer with methods to be called,\n * or the first of three possible handlers, which is the handler for each value emitted from the subscribed\n * Observable.\n * @param {Function} error (optional) A handler for a terminal event resulting from an error.
