CHANGELOG

2.4.0

ENHANCEMENTS

  • Add support for EFA on Centos 7, Amazon Linux and Ubuntu 1604
  • Add support for Ubuntu in China region cn-northwest-1
  • SGE:
    • process nodes added to or removed from the cluster in batches in order to speed up cluster scaling.
    • scale up only if required slots/nodes can be satisfied
    • scale down if pending jobs have unsatisfiable CPU/nodes requirements
    • add support for jobs in hold/suspended state (this includes job dependencies)
    • automatically terminate and replace faulty or unresponsive compute nodes
    • add retries in case of failures when adding or removing nodes
    • configure scheduler to handle rescheduling and cancellation of jobs running on failing or terminated nodes
  • Slurm:
    • scale up only if required slots/nodes can be satisfied
    • scale down if pending jobs have unsatisfiable CPU/nodes requirements
    • automatically terminate and replace faulty or unresponsive compute nodes
    • decrease SlurmdTimeout to 120 seconds to speed up replacement of faulty nodes
  • Automatically replace compute instances that fail initialization and dump logs to shared home directory.
  • Dynamically fetch compute instance type and cluster size in order to support updates in scaling daemons
  • Always use full master FQDN when mounting NFS on compute nodes. This solves some issues occurring with some networking setups and custom DNS configurations
  • List the version and status during pcluster list
  • Remove double quoting of the post_install args
  • awsbsub: use override option to set the number of nodes rather than creating multiple JobDefinitions
  • Add support for AWS_PCLUSTER_CONFIG_FILE env variable to specify pcluster config file

CHANGES

  • Update openmpi library to version 3.1.4 on Centos 7, Amazon Linux and Ubuntu 1604. This also changes the default openmpi path to /opt/amazon/efa/bin/ and the openmpi module name to openmpi/3.1.4
  • Set soft and hard ulimit on open files to 10000 for all supported OSs
  • For a better security posture, we're removing AWS credentials from the parallelcluster config file Credentials can be now setup following the canonical procedure used for the aws cli
  • When using FSx or EFS do not enforce in sanity check that the compute security group is open to 0.0.0.0/0
  • When updating an existing cluster, the same template version is now used, no matter the pcluster cli version
  • SQS messages that fail to be processed in sqswatcher are now re-queued only 3 times and not forever
  • Reset nodewatcher idletime to 0 when the host becomes essential for the cluster (because of min size of ASG or because there are pending jobs in the scheduler queue)
  • SGE: a node is considered as busy when in one of the following states "u", "C", "s", "d", "D", "E", "P", "o". This allows a quick replacement of the node without waiting for the nodewatcher to terminate it.
  • Do not update DynamoDB table on cluster updates in order to avoid hitting strict API limits (1 update per day).

BUG FIXES

  • Fix issue that was preventing Torque from being used on Centos 7
  • Start node daemons at the end of instance initialization. The time spent for post-install script and node initialization is not counted as part of node idletime anymore.
  • Fix issue which was causing an additional and invalid EBS mount point to be added in case of multiple EBS
  • Install Slurm libpmpi/libpmpi2 that is distributed in a separate package since Slurm 17
  • pcluster ssh command now works for clusters with use_public_ips = false
  • Slurm: add "BeginTime", "NodeDown", "Priority" and "ReqNodeNotAvail" to the pending reasons that trigger a cluster scaling
  • Add a timeout on remote commands execution so that the daemons are not stuck if the compute node is unresponsive
  • Fix an edge case that was causing the nodewatcher to hang forever in case the node had become essential to the cluster during a call to self_terminate.
  • Fix pcluster start/stop commands when used with an awsbatch cluster

2.3.1

ENHANCEMENTS

  • Add support for FSx Lustre with Amazon Linux. In case of custom AMI, The kernel will need to be >= 4.14.104-78.84.amzn1.x86_64
  • Slurm
    • set compute nodes to DRAIN state before removing them from cluster. This prevents the scheduler from submitting a job to a node that is being terminated.
    • dynamically adjust max cluster size based on ASG settings
    • dynamically change the number of configured FUTURE nodes based on the actual nodes that join the cluster. The max size of the cluster seen by the scheduler always matches the max capacity of the ASG.
    • process nodes added to or removed from the cluster in batches. This speeds up cluster scaling which is able to react with a delay of less than 1 minute to variations in the ASG capacity.
    • add support for job dependencies and pending reasons. The cluster won't scale up if the job cannot start due to an unsatisfied dependency.
    • set ReturnToService=1 in scheduler config in order to recover instances that were initially marked as down due to a transient issue.
  • Validate FSx parameters. Fixes #896 .

CHANGES

  • Slurm - Upgrade version to 18.08.6.2
  • NVIDIA - update drivers to version 418.56
  • CUDA - update toolkit to version 10.0
  • Increase default EBS volume size from 15GB to 17GB
  • Disabled updates to FSx File Systems, updates to most parameters would cause the filesystem, and all it's data, to be deleted

BUG FIXES

  • Cookbook wasn't fetched when custom_ami parameter specified in the config
  • Cfn-init is now fetched from us-east-1, this bug effected non-alinux custom ami's in regions other than us-east-1.
  • Account limit check not done for SPOT or AWS Batch Clusters
  • Account limit check fall back to master subnet. Fixes #910 .
  • Boto3 upperbound removed

  • Allow users to force job deletion with SGE scheduler

CHANGES
