python + cluster computing

[Uwe Schmitt]

Hi,

I found several Python bindings for the MPI protocol,
can anybody report some opinions and experiences ?

Greetings, Uwe.

Peter Christen and I have used Ole Nielsen's PyPar package (see
http://datamining.anu.edu.au/~ole/pypar/) in our Febrl probabilistic
record linkage engine (see
http://datamining.anu.edu.au/projects/linkage.html) with excellent
results. I have also been experimenting with its use in a parallel data
summarisation engine. It is easy to install and is very easy to use,
mainly because it only wraps a small portion of MPI - but just those
parts you really need (at least we haven't missed anything yet). Its
ability to pass any picklable Python object around the cluster is a real
bonus, and the speed at which it passes Numeric Python arrays using
"raw" mode is very impressive. Ole is also very helpful, and is actively
involved in parallel computing work on a daily basis (using PyPar, no
doubt).
