Hi all!! I'm using Sage 4.6 compiled from source on a 4 CPU (Intel Xeon) server with Ubuntu 10.04 and on a 114 CPU (Intel Xeon) cluster with Rocks (now I'm use only one node with 16 CPU).
I'm trying to run my python scripts that include mpi4py. On the server I get this error sage: import mpi4py.MPI /home/ziosi/.local/lib/python2.6/site-packages/mpi4py/MPI.so: undefined symbol: _PyByteArray_empty_string and on the cluster this ImportError: /home/ziosi/sage-4.6/local/lib/python2.6/site-packages/ mpi4py/MPI.so: undefined symbol: MPI_Type_create_f90_real In the mpi4py google group I've found this (august 2009!!!): http://code.google.com/p/mpi4py/issues/detail?id=8 where they suggest to recompile the module with some options. The problem is that I don't know how to do this with the sage installation of the module and I can't rebuild sage on the cluster because I need to ask my sys_admin for this! Do you have any suggest please??? Thanks!
