I'm back. The problem didn't show up for a few weeks but it's back. I now see 3 tasks than ran for 25000 seconds and obtained 20 credits. One of these is task 571259532. Thank you for looking at this.

Regards,

François

I do not know if the problematic tasks have been removed but all completed tasks of the last 24-48 hours are fine.

Unfortunately I'm getting more and more of these tasks. If the problem does not get solved I will have to work for another project. It is sad because Rosetta is my favourite but I still want to be appreciated for the effort.

Polian,

These 4 computers are all different, with no BIOS options forced (like overclocking). All are running Ubuntu Server 12.04 with the latest BOINC for Linux version (7.0.28). These computers are rebooted once every two-four weeks, when an Ubuntu upgrade requires it. I'm talking about these 4 computers because they all get the problem after running a 25,000 seconds task.

Up to know I did not believe the problem could come from the computer/OS. I thought the problem could come from Rosetta or the BOINC program itself. I'm surprised I'm the only one to get the problem since I have multiple, all different computers. Only common point between these computers is the BOINC software version and the OS.

Please let me know if you have more specific questions I could answer. Thank you for your help on this.

Hello,

For a while now I only get 20 credits for tasks that ran for 25,000 seconds. You can see this for task 557922201 (WU 506964570). I have tasks that ran for 20,000 seconds that obtained 90 credits. It seems there is a magic limit that when hit the credits drop. I have 4 machines running Rosetta and they all face the same problem.

Thank you for reading this thread.

This is strange since the same computers just changed the OS and BOINC version, physically they are the same. However, setting higher value for used memory seemed to help, it is now 3 days tasks are running fine. Thank you for the help!

Hello,

I would like to add that I'm on the impression that this may also be related to not using 100% of the CPU time. It's still hot in August and I do not want the computers to heat, so I set the CPU usage (in the BOINC options) to 75%. Before that it was two days it ran at 100% without the "Calculation waiting" problem.

It just happened. I cancelled the task and you should see its details. The task name is "Tc705_dimaio_chunk_recombinitions_SAVE_ALL_OUT_IGNORE_THE_REST_52830_16132" and its ID is 526653146. Workunit ID is 479255001.

Please let me know if you need more.

Hello,

I'm using few computers with Ubuntu Server. All of them were calculating fine when they were as 10.04, but all those that were updated to 12.04 will very often show calculations as "Calculation waiting" (or something similar, I'm running in French). I must kill the waiting calculation else it is blocking all the other ones that are waiting to start.

The computers with the problem are running BOINC 7.0.27.

Please let me know if you need more information.

Thank you for looking at this.

François
