Hmmm - sorry - Yep - i did the Mini-Distribution - Boot Disks and
the rest based on Debian.
BTW: The (poor documented) boot disk + mini distribution etc can be
found on ftp://move.mediaways.net/pub/cluster
mostly under testing ...

You cant measure the performance like this as all Benchmarks like
linpack are designed for homogenous clusters where every node
has the same performance. Also they do NOT include fail
recognition of nodes.
We made a linpack on a 50 Node Alpha Subcluster which has been reproduced
in the iX (Magazin for IT in Germany) laboratorium and they archived
31.3 GFlops as far as i remember. This has been done with LinPack.

We have no clue - The TV Station here in Germany which did a TV
Show in whose program this was shown cared on the Guiness Book of Records -
AFAIK the Guiness people meet again in March and maybe we know more then.
