High End POWER7 systems, like the POWER7 795, support configurations of up to 256 physical processors. Most of us can only dream of working on a system of this size. For those of us that are fortunate enough to play with these big boxes, you may find collecting and reviewing CPU related performance data a challenging task.   With 256 physical POWER7 processors, where each processor has 4 threads enabled (SMT 4), there will be up to 1024 logical CPUs active on the system. As a consequence, a lot of performance monitoring data will be... [More]
