after installing PETSc and petsc4py in my own $WORK, I can run sequentially, but if I run on more than one core it hangs when importing firdrake. I traced this down to the call of PETSc._initialise(args, comm) in the method init() in petsc4py/build/lib.linux-x86_64-2.7/petsc4py/__init__.py, which just does not return. It does pick up my PETSc installation correctly (printed out path, arch in ImportPETSc method in lib/__init__.py).
I build the PETSc branch mlange/plex-distributed-overlap (same as in $FDRAKE_DIR) with the same configure options use there, and then I build petsc4py with make.
Any ideas?
Thanks,
Eike
