Hmm... if that's the case, how would you rate quad-P3Xeon (1MB and 2MB cache)? The reason is that I always prefer SMP over cluster, simply for less component counts, less maintenance, better IO design, etc. Quad motherboards are available from Supermicro, and P3 Xeon are relatively cheap now. -- William Park, Open Geometry Consulting, <opengeometry@yahoo.ca> 8 CPU cluster, NAS, (Slackware) Linux, Python, LaTeX, Vim, Mutt, Tin
