Thanks, it seems a bug in MPI or on our side. As Matt said, can you run with -matstash_legacy? Also, make sure to run with a debug version of PETSc (configure using —with-debugging=1). How feasible is to write a driver code to run with the same mesh, same discretization and same equations to solve but with the matrix assembly only? Does it hang in that case too? > > Regards, > Manav >
