In case of non-cooperative sysadmins, can't you just have instances of MPI installed on your accounts on the slaves? I presume each slave has a Sage installation (with OpenMPI), so this probably means you need to create symbolic links to appropriate directories, and/or perhaps setting LD_LIBRARY_PA

Yeah, Parallel Python looks really neat. However, I actually use quite a bit of the inter-process communication parts of MPI in my code; and PP doesn't seem to have as useful primitives for that. Is there really no sensible way to use OpenMPI and Sage on more than one computer? // Mikael On Jan

Hi Mikael, I'd have looked into using Parallel Python (http:// www.parallelpython.com/) which is just a Python library. If it worked with Sage, it would be a worthwhile addition to Sage packages... Lately there is an ongoing project to make Sage notebook well- scalable, but I do not know if parall
