I've compiled PETSc with MUMPS support, and I'm trying to run a small test problem, but I'm having some problems. It seems to begin just fine, but what I notice is that on one process (out of 64), the memory just keeps going up and up and up until it crashes, while on the other processes, the memory usage is reasonable. I'm wondering if anyone might have any idea why? By the way, my command file is like this:
-ksp_type preonly -pc_type lu -mat_type aijmumps -mat_mumps_cntl_4 3 -mat_mumps_cntl_9 1 Randy ps. This happens after the analysis stage and in the factorization stage.
