Summary:

Slackware 13.1 x86 fully patched - incorrect CPU Time
OpenSuSE 11.3 x86 fully patched - incorrect CPU Time
Fedora 13 x86 fully patched - incorrect CPU Time
Ubuntu 10.04 x86 fully patched - correct CPU Time

The system requirements for this project should updated.

$ top compare with the BM task properties wont work because the PID resets with each loop i.e. restarts at 0:00:01. What could work is installing the old 6.2.28 client and setting the <checkpoint_debug> log flag... then an amount of staring is required watching the CPU counter and the checkpoints logged to see if there is a freeze or a skip back of some kind. As eluded in my earlier post in this thread, open 2 BOINC Managers and tile them horizontal, one in the message view, the other in the tasks view, so both parts can be watched simultaneous.

At least we know it's something that seemingly Ubuntu, the distro used for testing both by Berkeley BOINC developers and at WCG is not exhibiting this behavior. Just hoping more reports come in. Presume there always to have been used a native Linux disk fs (ext3/ext4), not NTFS or FAT16 or the such.

With a remote monitoring of the BM custom compile 6.6.76 ** you can actually watch Elapsed and CPU time side by side.
