Hi everyone, can someone tell me what the support status of Magny-Cours is? In upstream's release notes and knowledgebase, I have found some obscure (to me) notes stating that there is some support with 5.4, 2.6.18-164.9, some more with 5.5, and still more with 6. Currently, we have a bunch of 6168-based 4-core machines here, and while they are quite stable with 5.4 and kernel 2.6.18-164.11.1, performance of our main hpc application is abysmal. It is 48-way multithreaded and yields hardly even half the expected performance; what is more, performance is varying from run to run by something like +/- 30%.
