Others might be able to give you more a accurate explanation. The way I understood it, in OpenMPI 1.4, you need to write all checkpoints to a single, shared location. That's why you generally want a shared file system. Now I'm pretty sure you can change the directory to which the checkpoints are written. If you $HOME isn't a shared directory, you can point OpenMPI to write the checkpoints to the shared directory instead. In OpenMPI 1.5 (unstable), some magic allows you to create the checkpoints and restore them without a shared directory. Regards,
