I awoke this morning to find my client idle all night for no reason. My system idle process was at 99%. No relevant error or warning messages were in the log. I shutdown the client, reopened it and it started running again like normal. This might be a bug with the new client, so be warned.

Did BOINC run a periodic benchmark overnight? This has been seen on the Sulphur-cycle alpha and beta projects, with BOINC generating messages sucha as the following:

Had a benchmark been run and got messages like this:

If so, Chris Sutton and Thyme Lawn have reported it to the BOINC development list.

Yes it did. Great, the problem has been reported. Thanks for the replys.

Why is a benchmark even run for this type of project?

The benchmark is part of BOINC, and it's built in to run every 5 days.

It's needed for projects where credits are claimed by clients based on their benchmarks and granted by the server based on cross-comparison of what other computers claim for the same workunit. Which is not the way CPDN works.

Is there a work around yet for this problem? I've already lost days of CPU time as a result to this bug.

You can check out <a href="http://climateapps2.oucs.ox.ac.uk/cpdnboinc/forum_thread.php?id=2921">this thread</a> and determine if you want to use the 4.45b version that Ralic (Chris Sutton) has compiled. It does not suffer the benchmark problem. I've been running it the last week or so without problems.

Not much from UCB but you can use Chris Sutton's compilation of BOINC 4.45b that - among others - prlong benchmark timeout from 10 to 30 seconds. This was found as a working method to overcome BOINC-CPDN-benchmark bug/obstacle.
