I am running BOINC v5.10.45. The only project I am working is rosetta@home. I am using 2 processors to work 2 WUs simultaneously.

Occasionally, I need to suspend the project. Typically, I will do this via the Suspend button on the Projects tab.

I have noticed that if either task progress is greater than 50%, upon resuming the project that task progress will jump to 100% and the task will “complete”. This will happen to both tasks if both have progressed beyond 50%. (50% is an approximate value, derived anecdotally.)

This behavior also occurs (for individual tasks) when suspending and resuming from the Tasks tab.

The “Results” information for My Computers on the Rosetta web site indicates success on these tasks, but I am wondering…

Is this “partial job” completion of any benefit?
Do I have a configuration problem?

There is already a thread discussing this in the Number Crunching forum. But it doesn't have as specific a problem description. So let me try to address your specific questions, then check the other thread for the ongoing discussing.

Yes, a partial completion of a task is generally useful. You can check the info. on your results page and see if it got any errors. Tasks usually have multiple models, and one bit of the science is done at the end of each model, so Rosetta modified some things to get these to report in and be accepted when possible.

As for change on your end, you want to review your computing preferences, either on the website for the venue of this machine, or in the machine's local preferences. You want to make sure that tasks remain in memory while suspended. This will preserve all of your work up to that point, and allow the task to resume where it left off, rather then having to revert to a checkpoint (assuming you don't exit BOINC, or power off the machine). Changes made on the website will take effect the next time your machine contacts the project.
