[Mesa-users] Regarding number of threads in M1

[ABHIJNAN KAR 20064]

Thanks for the reply! I tested with various omp_number_of_threads. I set it to 6,8,16,32 but the computation time was more or less similar(for 287 steps).It took around 5 mins for 287 steps . The lowest time was 4.77 minutes with threads= 8. Setting the threads to 6 or 16 didn't improve computation time, rather it got a bit slow(by few seconds).
