OK, so IPython uses mpi4py and openmpi?
IPython could make use of it, but it doesn't have to. It has its own
scatter/gather and task-scheduling capabilities, too. It also doesn't need
to be openmpi, there are also other
MPI is more comparable to Mathematica's underlying MathLink C libraries. We
also have an mpi4py optional spkg that maps the C to a Python API,
essentially one-to-one. Its not pretty, but if you know MPI then you can
immediately use it. There is a mini-introduction and a sample program at

Well my Computing Independent Study class (aka CIS(theta)) put
together our cluster (aka Shadowfax). Apparently they found
documentation on http://www.sagemath.org about using parallel python
or mpi4py in SAGE. Does that work?

I don't know anything about that cluster, what management software does it run?
For example, when you update ipython you can submit your engines [1]
to the cluster nodes via the oracle grid

Thanx for this ticket info. It looks like this MPI pkg is now
installable as a special pkg? How do I do that? How do I use openMPI and
mpi4py in SAGE after the install?

MPI is _the_ standard for passing data between different CPUs and used to
write parallel programs on clusters and supercomputers. Its a rather
low-level C library and you need to spend some time learning it if you want
to use it effectively.
Your random assembly of lab PCs is probably not
I have the SAGE binary installed on 25 Ubuntu boxes in my classroom.
I wonder if there's anyway to use this as a cluster to run python code
in parallel? I recall some work to that end some time ago with dSAGE
and the @parallel decorator. However, dSAGE has not been part of SAGE
for a while and,
