Prefect executor integrations for HPC schedulers

QCSC Prefect Executor

Prefect executor integrations for local processes and QCSC HPC scheduler workflows.

Local execution

Set HPCProfileBlock.hpc_target to "local" and map the command's executable key to a path or command available on the Prefect worker. Local execution does not generate a job script and does not call a scheduler. It invokes the command directly with cwd=work_dir.

With launcher="single", the command is:

executable default_args... user_args...

With another launcher, it is:

launcher mpi_options... executable default_args... user_args...

environments are merged into the worker process environment. Values are passed literally without shell expansion. modules and pre_commands are explicitly unsupported for local execution and cause ValueError before the process starts.

Bulk execution

BulkJobSpec supports optional per-job execution_profile_block and hpc_profile_block overrides. None uses the runner/API default blocks. The single-submit bulk paths use these effective blocks for submission and group monitoring by effective hpc_profile_block; native PJM bulk mode rejects per-job block overrides because one generated script/profile is shared by all subjobs.
