Dear Developers,
I found the out of core parameter in the external solver MUMPS is important
when using with cygwin because the default directory /tmp/ simply does not
exist in windows. So you may consider putting:
? ierr = PetscOptionsString("-ooc_tmpdir", "The Out of Core directory", "None",
lu->id.ooc_tmpdir, lu->id.ooc_tmpdir, 256, PETSC_NULL);
?in the function:
PetscErrorCode PetscSetMUMPSOptions(Mat F, Mat A)
in the file: mumps.c
So that the users can enter the temporary directory of their choice.
Kind regards,
Pham Van Ha
