I respectfully disagree (IRD). I am building a cluster to support
high-performance computing, specifically meteorological models. The current
version of the code runs on UltraSparc-III non-copper based system. The Sun
sales rep loaned us an x4200 and I borrowed times on a SunFire V490 both
configured with 4 cores and 4gb or memory. The wall-clock run time for the
x4200 was 15 hours and the v490 was 9 hours. Granted the x4200 was cheaper, but
you also get cheap hardware. The x4200 has too many sharp edges and reminds me
of a beige box where the disk drives are held in place with foam blocks.
