These are single system results with MVAPICH. They will run on InfiniBand which is why MVAPICH was used. The quad core runs were 2 processes per socket. The executables were created with the latest Portland Group f90 and the optimisation flags were used for each chip. The Barcelona binary used "-tp barcelona-64" and the Xeon binary used "-tp core2-64." As soon as I am able I will be running this test on Harpertown processors. I should then have permission to publish the details of the testing. >> I recently ran a customer's weather modeling code on a >> variety of machines. This program is very sensitive to >> memory.
