Hi all,

I just found an old outsourced computer which would work pretty well just for crunching Rosetta tasks.
Unfortunately the computation stopps after some seconds with "computation error".

Does anyone have an idea, where the problem could be? See the event log below:

You're looking at the wrong log file to see much about THIS problem.

To see the one with more information for this problem:

If you're using the simple view of the BOINC Manager, find View near the top line, click on it, then click on Advanced View.

Click on Projects in one of the top lines, then Rosetta@home, then Your tasks.

In the Status column, find one of the failed tasks. Ignore those shown as In progress - they don't have the other log file yet. Ignore those shown as Completed and validated for now unless you want to see one without errors for comparison purposes.

When you find one, click on the number in this line, but in the Task column. This gives the log file specific to that task.

Scroll down as needed. In this case, look at the line starting with unzip, which shows the error triggering all other errors for this task,

I've looked at this file for some of your failed tasks, and have thought of three possibilities:

1. The task was built improperly, and the list of files it needs left out one or two of the zip files. It may have assumed, incorrectly, that some previous task had downloaded it or them.

2. Your antivirus program hid one or both of those files. You might check the log file of your antivirus program, if it has one.

3. These tasks used version v4.21 of the Rosetta application, which I have not seen mentioned before. That version might have the wrong builtin names for files to send to unzip.

For 1, about all you can do is wait for more tasks that fix this problem.

For 2, you might have to tell your antivirus program not to scan the directories for BOINC.

For 3, you might watch the forums for mentions of that version, to see if similar problems are reported by others.

On another subject, I also looked at the specs for that computer, which runs Windows XP. You might look for threads on whether the current versions of Rosetta are compatible with Windows XP.

The current tasks take up to 2 GB of memory each and sometimes more, so you may have problems with the tasks running out of memory once you can get them to run longer, if you allow one task each for the 4 virtual CPU cores on that computer. You may have to limit it to only one task at a time. That computer has only 4 GB of main memory, and some of it is reserved for the Windows operating system.
