[petsc-users] MUMPS failure

[Chris Hewson]

Hi All,

I have been having a problem with MUMPS randomly crashing in our program
and causing the entire program to crash. I am compiling in -O2 optimization
mode and using --download-mumps etc. to compile PETSc. If I rerun the
program, 95%+ of the time I can't reproduce the error. It seems to be a
similar issue to this thread:

https://lists.mcs.anl.gov/pipermail/petsc-users/2018-October/036372.html

Similar to the resolution there I am going to try and increase icntl_14 and
see if that resolves the issue. Any other thoughts on this?

Thanks,
