Grid computing

[Leen Toelen]

Hi,

I have some very big calculations to do (CPU-intensive, not
data-intensive), taking weeks on even the fastest servers (3.5Ghz, 4GB
RAM). I would like to build a grid to speed things up, because the
jobs can be easily parallellized. There is a plethora of software to
do this, but what is your opinion. Being completely open-source is one
requirement, and I would like to run it on ubuntu machines.

Thanks,
