Hi William, Thank you so much. Our power supply in each node is Lemacs (model P1M6400P). I will look into the power supply and see if that might be the culprit. PS. The fans seem to be making good contact with the CPU's. But, we haven't tried a heat sink compound yet. Maybe that will be our next step? -Bonnie |---------+------------------------------------> | | William Park | | | <opengeometry@yahoo.ca> | | | Sent by: | | | bioclusters-admin@bioinfo| | | rmatics.org | | | | | | | | | 12/29/2002 08:26 PM | | | Please respond to | | | bioclusters | | | | |---------+------------------------------------> >-------------------------------------------------------------------------------------------------------------------------------| | | | To: bioclusters@bioinformatics.org | | cc: | | Subject: Re: [Bioclusters] problems with AMD Athlon 2000+ MP | >-------------------------------------------------------------------------------------------------------------------------------| On Sun, Dec 29, 2002 at 08:01:02PM -0600, BHurwitz@twt.com wrote: > Hello, > > We have a 20 CPU cluster which has AMD Athlon 2000+ MP processors.

Use heatsink compound, if you have to. - I think your culprit may be power supply. Good case and power supply cannot be over-emphasized. I recommend Antec or Enlight. - Intel runs a lot cooler. P3 is more stable, but don't have the crunching power of AMD 2000+. If you have the money, go for quad-Xeon. -- William Park, Open Geometry Consulting, <opengeometry@yahoo.ca> Linux solution for data management and processing. _______________________________________________ Bioclusters maillist - Bioclusters@bioinformatics.org https://bioinformatics.org/mailman/listinfo/bioclusters
