I ran then program with 1500 threads and in top it looked the this:
PID USERNAME THR PRI NICE SIZE RES STATE C TIME CPU COMMAND
20382 yuri 1500 99 0 641M 462M umtxn 0 0:00 19623.14%
Where can I read how CPU column is calculated?
Some time ago I saw another weird fenomenon when CPU column: 5% CPU load
for the pocess that just cycles in CPU.
7.2-STABLE, i7-920 (4 CPUs)
