Clustering

[Stephen]

Are you looking at the 1u Tesla or the x58 personal supercomputer they
are talking about...

I would look into RH mostly for compatability fo ahrdware as it is
tested by them, and for most packages... but the distro is really
dependant on your app.

Man they have really changed tesla, it used to be a bunch of gpu cards
in a box chained to a header and then 16 of those can be tied together
to a single machine.

but now you can buy a preconfigured clsuter
