|The biggest objection I've heard to using FreeBSD for parallel processing |clusters was the lack of a FreeBSD version of a certain commercial Fortran |compiler. FreeBSD (with net.inet.tcp.delack_enabled=0 in 3.0-current) |ought to have better network performance over the entire spectrum of |message sizes than Linux 2.0.x, so I want to see whether this has an |observable effect on parallel apps. The NAS Parallel Benchmarks are quite network intensive, there may be numbers for "Beowulf" clusters by now. There weren't when I was running on the DAISy cluster at Sandia (which ran FreeBSD at the time, '94-95). The DAISy numbers I measured for these were the best price/performance of *any* system at the time.
