Parallel threads : problem
Posted: Tue Sep 18, 2018 5:05 pm
Dear Bernd/Ralph,
I am now using MICRESS 6.4 version and have some problem with the execution of 'parallel threads' parameter. I am running a simulation and trying to implement the usage of different cores. I see that the simulation time is increasing with the usage of multiple cores. For example, my simulation finished in 30 s (wall-clock time) when I don't use parallelization but took 75 s when I try to run the same with the help of 4 cores and time increases with no.of cores. Assuming that the load was small on parallelized solver, I have tried by implementing the same with the bigger system but follows the same pattern of results. This seems confusing to me. Please, find the attached driving file that I was using. Could you please let me know what is going wrong with this?
Thank you.
Best regards,
Sudhee.
