General Multiprocessing

Datasheet internal name: core_Multiprocessing

SyncroSim supports multiprocessing, such that iterations, scenarios, and/or spatial tiles can be run in parallel across multiple processors.

The Multiprocessing system datasheet contains the following fields and options:

Display Name	Internal Name	Optional	Data Type	Default
Enable multiprocessing	EnableMultiprocessing	No	Boolean	True
Run multiple scenarios in parallel	EnableMultiScenario	No	Boolean	True
Copy scenario inputs for each job	EnableCopyExternalFiles	No	Boolean	False
Maximum number of jobs	MaximumJobs	No	Integer	7

Enable multiprocessing

Determines whether simulations should be run in parallel for the library.

Run multiple scenarios in parallel

Determines whether jobs for multiple scenarios should be run in parallel.

Copy scenario inputs for each job

Determines whether to copy the scenario inputs for each multiprocessing job. If False (default), then a copy of input files is not created for each multiprocessing job. Otherwise, a copy of inputs is created for each multiprocessing job. Applies only when the number of jobs is set to >1 in the datasheet. Should only be enabled if running on High-Performance Computing, as setting this to True can cause significant increases to memory use and storage.

Maximum number of jobs

Sets the number of threads to parallelize the simulations over.
