Hello, I wonder about how much number of cpu can use while running cplex python.

I saw some post which claim that cplex only can use 32 cpu cores.

The documentation says:

Threads parameter

Describes the effect of the threads parameter in parallel.

You manage the number of threads that CPLEX uses with the global thread count parameter (Threads, CPX_PARAM_THREADS) documented in the CPLEX Parameters Reference Manual. At its default setting 0 (zero), the number of threads that CPLEX actually uses during a parallel optimization is no more than 32 or the number of CPU cores available on the computer where CPLEX is running (whichever is smaller).

If you set the threads parameter to a value greater than its default of 0 (zero), then the number of threads that CPLEX uses equals that value. When you set the threads parameter to 1 (one), you enforce sequential operation, that is, processing on one thread only.
