check for thread compatibility.

When using multiple threads, the result of the execution is in most cases independent of the number of threads. However, a few operations mostly related to summations can create slightly different results depending on the number of threads, and therefore the results may depend on the number of threads. ThreadC can be used to force reproducible results. The execution is done as if there were ThreadC threads independent of the actual number of ThreadS (ThreadS > ThreadC).

This method can be used to define how many threads CONOPT should simulate. The argument ThreadC is interpreted as follows:

• ThreadC = 0: let the execution be controlled by ThreadS defined above,
• ThreadC > 1: simulate the use of ThreadC > ThreadS threads.

The upper bound on ThreadC is currently 8.

Parameters

threadc

the number of threads CONOPT should simulate
