The 9 nodes are the server (Pentium IV) and the 8 newest nodes (Celerons). The mpich library and executables are ssh-based, icc-compiled.

Initial tests :

The last one was based on atlas 3.6.0 compiled on one of the celeron nodes (aspera), and it looks reasonably good (reaching 8.2 Gflops).

Optimisation :

Final HPL 9-node benchmark, best performance 10.32 Gflops.
