Submodule to handle the SLURM configuration for a WorkflowTask

`SlurmConfig` ¶

Bases: BaseModel

Abstraction for SLURM parameters

NOTE: SlurmConfig objects are created internally in fractal-server, and they are not meant to be initialized by the user; the same holds for SlurmConfig attributes (e.g. mem_per_task_MB), which are not meant to be part of the FRACTAL_SLURM_CONFIG_FILE JSON file (details on the expected file content are defined in SlurmConfigFile).

Part of the attributes map directly to some of the SLURM attribues (see https://slurm.schedmd.com/sbatch.html), e.g. partition. Other attributes are metaparameters which are needed in fractal-server to combine multiple tasks in the same SLURM job (e.g. parallel_tasks_per_job or max_num_jobs).

Attributes:

Name	Type	Description
`partition`	`str`	Corresponds to SLURM option.
`cpus_per_task`	`int`	Corresponds to SLURM option.
`mem_per_task_MB`	`int`	Corresponds to `mem` SLURM option.

`shebang_line`	`str`	Shebang line for SLURM submission scripts.
`extra_lines`	`Optional[list[str]]`	Additional lines to include in SLURM submission scripts.
`tasks_per_job`	`Optional[int]`	Number of tasks for each SLURM job.
`parallel_tasks_per_job`	`Optional[int]`	Number of tasks to run in parallel for each SLURM job.
`target_cpus_per_job`	`int`	Optimal number of CPUs to be requested in each SLURM job.
`max_cpus_per_job`	`int`	Maximum number of CPUs that can be requested in each SLURM job.
`target_mem_per_job`	`int`	Optimal amount of memory (in MB) to be requested in each SLURM job.
`max_mem_per_job`	`int`	Maximum amount of memory (in MB) that can be requested in each SLURM job.
`target_num_jobs`	`int`	Optimal number of SLURM jobs for a given WorkflowTask.
`max_num_jobs`	`int`	Maximum number of SLURM jobs for a given WorkflowTask.
`user_local_exports`	`Optional[dict[str, str]]`	Key-value pairs to be included as `export`-ed variables in SLURM submission script, after prepending values with the user's cache directory.

`_parse_mem_value(raw_mem)` ¶

Convert a memory-specification string into an integer (in MB units), or simply return the input if it is already an integer.

Supported units are "M", "G", "T", with "M" being the default; some parsing examples are: "10M" -> 10000, "3G" -> 3000000.

Parameters:

Name	Type	Description	Default
`raw_mem`	`Union[str, int]`	A string (e.g. `"100M"`) or an integer (in MB).	required

Returns:

Type	Description
`int`	Integer value of memory in MB units.
