Hello Dr. Satish, Thanks for your intellectual reply.

Motherboard: Intel Entry Server Board Intel S3200SHV with intel 3200 Chipset supporting 1333/1066/800 MHz FSB . RAM: 2GB DDR2 800MHz ECC System Memory. What memory-bandwidth/CPU-core will be there for this system? Any other comment/remark? My area work deals in sparse matrices. I near future I would like to add 12 similar compute nodes in the cluster. On such a cluster what if I relapce "C2D 2.66 GHz FSB1333 processor" with "Intel Xeon 3070/3075 2.66 GHz FSB1066/1333 processor"? Would there be any significant improvement in performance? with best regards, Amjad Ali. -------------- next part -------------- An HTML attachment was scrubbed...
