Parallelization for Large Simulation domain
Posted: Mon Jan 28, 2019 4:57 pm
Hi Bernd/Ralph,
I am currently trying to check the possibility of simulating the solidification process during casting in order to look at chemical segregation by considering a large domain in the order of mm.
Would parallelisation help in this cause?
As mentioned in one of the forum threads, diffusion solver and stress solver scales up well and speed up can be expected in problems dealing with these solvers. Does parallelization help when we consider larger domain sizes for segregation problem (which would be a diffusion controlled problem)?
I tried performance checks with the Alpha-Gamma example in Micress (T001_Delta_Gamma_dri) using 3 6(default number used in the example), 12, 24 threads. There seems to be no difference with the wall clock and the CPU times. How do I know if all threads are active/used in this case?
Please let me know what is going wrong with this and your comments on the above problem.
Thank you.
Best Regards,
Sai
