[ubuntu-uk] FW: High Performance Computing

[Ian Pascoe]

Hi Dave

I'm surprised about the kernal level - I'd have thought with all the tooing
and froing about running virtual machines and so on just lately that the
projects would be clamboring to get the virtualisation stuff into the main
line 2.6.2x kernal.

Or, have I led myself up the garden path of total mis understanding out onto
the back lane of total ignorance by getting virtualisation and cluster /
parallel computing mixed up?

Ian

I think this is tricky: the only really useable, open cluster project is
OpenMosix which is currently only 'alpha'-level for 2.6.x kernels.

The preferred environment for OpenMosix is 2.4.x kernels: something like
Debian Sarge would be the best bet for that; the main problem being that
if one is tied to a 2.4.x kernel, hardware support for new systems is
tricky.  Then again, a cluster works well with fairly basic (old)
hardware.

I'd be interested in seeing developments in this area, although it's
unlikely to be Ubuntu-specific.  The OpenMosix project essentially
provides (if I've understood it correctly) a kernel patch and some
userland/management tools.

Dave.
