I have not tried to checkpoint an mpi4py application, so I cannot say for sure if it works or not. You might be hitting something with the Python runtime interacting in an odd way with either Open MPI or BLCR.
Can you attach a debugger and get a backtrace on a stuck checkpoint? That might show us where things are held up. -- Josh On Aug 9, 2010, at 4:04 PM, <ananda.mu...@wipro.com> <ananda.mu...@wipro.com> wrote: > Hi > > I have integrated mpi4py with openmpi 1.4.2 that was built with BLCR 0.8.2. > When I run ompi-checkpoint on the program written using mpi4py, I see that > program doesn’t resume sometimes after successful checkpoint creation.
