phenotypic.sdk_.slurm.estimate_concurrent_capacity(partition: str, cpus_per_task: int = 1, mem_gb_per_task: float = 4.0) → int[source]#

Estimate max concurrent tasks from partition resources via sinfo.

Queries SLURM’s sinfo for the given partition to determine total CPUs, memory, and node count, then estimates how many tasks can run concurrently given per-task resource requirements.

Parameters:

  • partition (str) – SLURM partition name.

  • cpus_per_task (int) – CPUs requested per task.

  • mem_gb_per_task (float) – Memory in GB per task.

Returns:

Estimated number of concurrent tasks. Falls back to 100 if sinfo is unavailable.

Return type:

int

Examples

>>> capacity = estimate_concurrent_capacity("compute")
>>> capacity >= 1  # Always at least 1
True
