A couple of points that we've found: 1) Use a mainline kernel, we've found benefit of that over stock CentOS kernels. 2) Make sure you don't disable ACPI on Barcelona as the K8 NUMA detection hack doesn't work with K10h and you'll find the kernel is faking NUMA.. But, as ever, it depends on what your code does - if it's not memory heavy and is more integer based then Intel will likely do better. cheers, Chris -- Christopher Samuel - (03) 9925 4751 - Systems Manager The Victorian Partnership for Advanced Computing P.O.
