Description

FFRSNCPU

<Integer>

Default = number of cpu's used by OptiStruct.

PARAM, FFRSNCPU relates to the FastFRS interface.

This parameter is used to define the number of cpu’s to be used by the external FastFRS solver. This parameter will set the environment variable OMP_NUM_THREADS. The default value is the current value of OMP_NUM_THREADS.

Note

1.If FFRSNCPU is not set, but AMLSNCPU is set, the FastFRS will use the number of cpu’s specified by AMLSNCPU.
2.OptiStruct and FastFRS can be run with different allocations of processors. For example, OptiStruct can be run with one processor and FastFRS with four processors in the same run.
3.This parameter is only valid when PARAM, FFRS or the run option –ffrs is set to YES.

Refer to FastFRS Usage (Fast Frequency Response Solver) in the User's Guide for more details.
