Package: linux-source Version: 2.6.18.dfsg.1-18etch6 Severity: normal
I have some machines with 8 CPUs (dual Intel Xeon quad-core CPU chips), used for long-running calculations; normally there are no short-lived processes. If all processes are "niced" to the same or nearby level, then things behave as expected. But if there is a large difference in the "nice" level (e.g. one job at level 15 and 8 jobs at level 18), then one CPU is left idle: total CPU percentages adding to 700% and "top" shows idleness at 12.5%. (Under some similar conditions I have also observed 2 idle CPUs.) Please let me know if you need further details.
