NAS Parallel Benchmarks, v.2.3, 4 old nodes

The benchmarks were built with the Intel compilers. MPICH was used as the MPI implementation. Process migration to the newest nodes was avoided by locking the ssh deamon (not the best solution). The nodes were pc13, pc14, pc15, pc16 (733 MHz, PIIIs). Results :
