[petsc-users] External package SCALAPACK does not work on Microsoft Windows

[Pham Van]

Dear Team,

I used to compile petsc with external package mumps in version 3.1

However, today I tried 3.2 and get many of such error massage:

External package SCALAPACK does not work on Microsoft Windows


It happens also with blacs. How can I build mumps without those pakages?

Kind regards,
PVH

I can see log_summary output when I use -log_summary [filename].


But the time of inserting the matrices values is almost the same when I use PCJACOBI  to run the code on GPU instead of PCSOR.They are all much longer than that when I run the code in CPU(I still use a small system to test it). The attachments are outputs of log_summary, c_jacobi_sum is the output of using CPU, PCJACOBI;g_sor_sum using GPU, PCSOR;g_jac_sum using GPU, PCJACOBI.

Sorry, someting is wrong with my file which stores the size of the matriex.
But I still can't see -log_summary output. I just see at the first time, after that, never.


It is written by PetscFinalize(). Find out why you don't get there. Also note that the option needs to be visible at PetscInitialize (through the command line/options file/environment).
