Dear All, We are in the process of buying new machines for calculation (mostly GROMACS, but also Gaussian 09, MEAD and other codes) to add to our cluster. We have the option of buying Dual Processor Intel Xeon X5650 with 6 cores or Quad processor AMD Opteron series 6100 (12 cores) or series 6200 (16 cores). The Quad processor machines (with Opteron 6274 - around 4200 euros plus VAT) are a bit cheaper than two machines with Dual processor Xeons (X5650 - around 5300 euros plus VAT).
I would like to ear about your experience with the Quad processor Opterons of this kind. Our cluster is used by a substantial number of people, which means that the machines will not likely be devoted to one job only at the time; sharing is probably going to occur (at least this is the optimum way to squeeze the most of our present Dual Dual Processor Intel Xeon X5650 (2 jobs at the same time)). Additionally, we would like to have benchmarks of GROMACS in the Opteron architectures. Or even better, if there is a kind soul having one of these Opteron machines around, we would be very happy to run our own benchmark (a tar file with an easy-to-run shell script that runs without supervision). Sellers/representatives of this type of machines should be kind to provide such possibility, but here in Portugal this is not usually possible.
