Hi all, I am using the montecarlo generator to investigate a mixture model recovery example.
analysis: miterations=5000;
type = mixture;algorithm=integration;starts=300 10;PROCESSORS=168 166;

When I submit the program specifying multiple threads, I receive the following error:
OMP: Error #34: System unable to allocate necessary resources for OMP thread:
OMP: System error #11: Resource temporarily unavailable
OMP: Hint: Try decreasing the value of OMP_NUM_THREADS.

It doesn't make sense to have more than 10 treads given starts=300 10;

You should use PROCESSORS=168 10;

With such a large number of threads you will be running 166 Mplus runs at the same time which will crush the memory.
