Hi, Redhat seems to include the cpuaffinity patch in their kernels, does someone has ever tried the Linux Multiprocessor Control Interfaces : http://www.ccur.com/rt_oss.asp It might be usefull for benchmarks purpose By the way, is there a way to desactivate linux (besides rebooting and modifying the bios) ?
