Hi,
I get the following error duing MatMatSolve. It works for smaller number of processes but if I increade the number pf processes used it crashes.
[25]PETSC ERROR:
[25]PETSC ERROR: Caught signal number 11 SEGV: Segm
I would start with valgrind see if it finds anything. If not and if you can
provide the code that reproduces the problem we can take a look at it.
