Threads

Threads is an option  that controls the number of threads or CPU cores to be used by a solver. It can be set as a command line parameter, a GAMS option or a model attribute.  Note that this does not alter the cores used in Grid computing. Numeric input is expected with the allowable numeric values being

it is implemented in the command line with the syntax

Threads=number

or as an option with

option threads=number;

or as a model attribute with

modelname.threads=number;

Non-positive values are interpreted as the number of cores to leave free so setting threads to 0 uses all available cores while setting threads to -1 leaves one core free for other tasks.
