I recently had the opportunity to perform some benchmarks (BLAST, Clustalw, Clustalw-mpi, and MrBayes) on one of the new quad chip, dual core Xeon (Paxville) servers from Intel. This isn't a comparative study between chips, but rather a look at how batch, multi-thread, and MPI jobs scale on this machine. The report is linked from our main page: http://bioteam.net Disclaimer: I did this work in my corporate guise at Bioteam. Intel provided the hardware, access to their compilers, and they paid for the preparation of the report. They did not, however, exercise editorial control over the content. -Chris Dwan The BioTeam
