Dear Umut,
Dear Ronan,Thanks for the information, there are some compilation flags for mumps in the documentation, but does that mean that when I compile gmm++ with these flags and lu_solve will use mumps?
No. You have to use MUMPS_solve.
One more question related to this subject, is that possible to keep the factorization information when using mumps as well?I just have a quick look on the file gmm_MUMPS_interface.h. Now, it seems that you can only solve once (but several solutions with only one factorization could surely be interfaced).
Best regards, Ronan
