Hi. I test to get solution about non-symmetric matrix Ax=B used cluster version direct sparse solver.
I used to MKL 2018 update 3 and the compiler is VS 2017.
I test to my application used cluster_sparse_solver both option centralized and distributed. (iparm[39])
And the solving time of distributed option solver is x3 ~ x5 slower than centralized option solver.
(The size of matrix about quarter million. Used same A and B, Ax = b result is same)
I tried the start and end domain number of distributed option solver is just divided number of process. (4 process, 0 ~ 30000, 30001~60000, ...)
Is there anything I did wrong? If not, what information should be used to divide the domain?
