Description

There are basically three ways to use a Python Task Managers:

  • Submit each Python Function as an individual job to the HPC cluster - supported in executorlib by the SlurmClusterExecutor and the FluxClusterExecutor.
  • Submit multiple Python Functions within one HPC job allocation - supported in executorlib by the SlurmJobExecutor and the FluxJobExecutor.
  • Submit multiple Python Functions to the same resources on a given HPC cluster - similar to the block_allocation=True for the SingleNodeExecutor, the SlurmJobExecutor and the FluxJobExecutor but for the SlurmClusterExecutor and the FluxClusterExecutor. This is the standard use case for solutions like https://www.dask.org and https://parsl.readthedocs.io/ so it might be an interesting addition to executorlib.

Research direction

The issue names no file or test. Start by comparing SlurmClusterExecutor and FluxClusterExecutor with SlurmJobExecutor and FluxJobExecutor, including the existing block_allocation behavior described in the issue. Clarify whether the goal is documentation or a new worker capability, then define completion around executing multiple Python functions on shared cluster resources.
