 - Many clusters have their own unique job scheduler or specific MPI/Slurm arguments necessary for launching jobs such as [Summit JSRun](https://docs.olcf.ornl.gov/systems/summit_user_guide.html#job-launcher-jsrun) or [LLNL Flux](https://computing.llnl.gov/projects/flux-building-framework-resource-management)
 - While the above Slurm/MPI/pdsh default options are enough for most job runs, advanced users may want to add arguments for optimization or debugging purposes

+In these cases, you will need to modify the DeepSpeed [multinode runner](https://github.com/microsoft/DeepSpeed/blob/17957728c0362bf8ae70feca308e491e55ef9feb/deepspeed/launcher/multinode_runner.py) utility to support your usecase. Broadly, these enhancements fall under two categories:
 
-##### Adding Launcher (e.g. [JSRun](https://docs.olcf.ornl.gov/systems/summit_user_guide.html#job-launcher-jsrun), [Flux](https://computing.llnl.gov/projects/flux-building-framework-resource-management), etc)
+##### 1. Adding a Launcher (e.g. [JSRun](https://docs.olcf.ornl.gov/systems/summit_user_guide.html#job-launcher-jsrun), [Flux](https://computing.llnl.gov/projects/flux-building-framework-resource-management), etc)
 
 In this case, you must add a new multinode runner class to `deepspeed/launcher/multinode_runner.py` and expose it as a configuration option in GPT-NeoX. Examples on how we did this for [Summit JSRun](https://docs.olcf.ornl.gov/systems/summit_user_guide.html#job-launcher-jsrun) are in [this DeeperSpeed commit](https://github.com/EleutherAI/DeeperSpeed/commit/9aed6c8500d7c492d85c5c88687322dbda70e370) and [this GPT-NeoX commit](https://github.com/EleutherAI/gpt-neox/commit/3782c7ae60f8624e566e3879b89bb09e8b59b869), respectively.

+##### 2. Modifying Run Command or Environment Variables
 
 We have encountered many cases where we wish to modify the MPI/Slurm run command for an optimization or to debug (e.g. to modify the [Slurm srun CPU binding](https://slurm.schedmd.com/srun.html#OPT_cpu-bind) or to tag MPI logs with the rank). In this case, you must modify the multinode runner class' run command under its `get_cmd` method (e.g. [mpirun_cmd](https://github.com/microsoft/DeepSpeed/blob/17957728c0362bf8ae70feca308e491e55ef9feb/deepspeed/launcher/multinode_runner.py#L135-L147) for OpenMPI). Examples on how we did this to provide optimized and rank-tagged run commands using Slurm and OpenMPI for the Stability cluster are in [this DeeperSpeed branch](https://github.com/microsoft/DeepSpeed/compare/master...EleutherAI:DeeperSpeed:v2.0-stability)
