[petsc-users] mumps get stuck with parmetis

[Alexander Grayver]

Can you set:

-mat_mumps_icntl_4 1

And send mumps output?
Also do you use lu or ilu? How large is your matrix?

Regards,
Alexander

Hi,

My code will hang at the solving stage when I use mumps with the runtime option -mat_mumps_icntl_28 2 -mat_mumps_icntl_29 2. If I remove these two options, my code works fine. I am using PETSc 3.2 and configure it with --download-mumps=1 and --download-parmetis=1. Could anyone give me any hints? Thanks.


Regards,
Wen
