The main point of KSE is ability to execute threaded processes on different CPUs on SMP machines, but as noted in http://www.my-opensource.org/lists/myoss/2003-06/msg00161.html there are must be several entities for one process in top or ps. Hm... just and idea - may be I must remap libraries for ps also to get what i want 8-) Benjamin Walkenhorst wrote: | Hello, | | Krok wrote: | |> But top/ps shows not several processes, but one process with CPU more |> then 100% sometimes : |> |> 611 mysql 20 0 142M 91832K kserel 3 6:57 165.09% 165.09% |> mysqld |> |> Is it normal ? | | | Do you happen to be running a multi-CPU system? | I recently experienced a similar thing with a threaded perl-script using | ~120% CPU on a | dual AthlonMP.
