-
CONCURRENT=TRUE | FALSE
specifies whether to run PROC OPTMILP in concurrent mode. You can specify the following values:
- TRUE
runs PROC OPTMILP in concurrent mode. The solver automatically runs the same problem on each grid node with different PROC OPTMILP options.
- FALSE
turns off concurrent mode for PROC OPTMILP.
By default, CONCURRENT=FALSE.
-
DETERMINISTIC=TRUE | FALSE
specifies whether to enable PROC OPTMILP to run deterministically when distributed or concurrent mode is enabled. The DETERMINISTIC= option is valid only when DISTRIBUTED=TRUE or CONCURRENT=TRUE. You can specify the following values:
- TRUE
runs PROC OPTMILP in deterministic distributed or concurrent mode. The procedure always returns the same solution for subsequent runs on the same grid.
- FALSE
runs PROC OPTMILP in nondeterministic distributed or concurrent mode.
By default, DETERMINISTIC=FALSE when you specify CONCURRENT=TRUE, and DETERMINISTIC=TRUE when you specify DISTRIBUTED=TRUE.
-
DISTRIBUTED=TRUE | FALSE
specifies whether to run PROC OPTMILP in distributed mode. For more information about this option as it relates to the standard PROC OPTMILP processing, see the section Parallel Processing. For more information about this option as it relates to the decomposition algorithm, see Chapter 17, The Decomposition Algorithm. You can specify the following values:
- TRUE
runs PROC OPTMILP in distributed mode.
- FALSE
turns off distributed mode of PROC OPTMILP.
By default, DISTRIBUTED=FALSE.
-
NTHREADS=number
specifies the maximum number of threads for PROC OPTMILP to use for multithreaded processing. The branch-and-cut algorithm can take advantage of multicore machines and can potentially run faster when number is greater than 1. The value of number can be any integer between 1 and 256, inclusive. The default is the number of cores on the machine that executes the process or the number of cores permissible based on your installation (whichever is less). The number of simultaneously active CPUs is limited by your installation and license configuration.
