1) Message boards : Number crunching : Problems with Rosetta version 5.67 (Message 41541) Posted 28 May 2007 by Ai-Leng Post: I have a work unit that seems to be "almost" stuck at 97% complete. The % complete has been slowly increasing (by about .4%) over the last two hours. I have work units set to complete in 4 hours, and we are going over 6 with this one. It is wuid=74278854 I have the same situation but I'm not overly concerned. The wu does get finished even if it does take a while at the end.

This concept is discussed here. BOINC will download more work when it has finished it's balancing to meet your resource shares between projects. [edit] I see you now have a new task download. Thanks. I was wondering what was going on. And yes, I have a work unit again. ^_^
3) Message boards : Number crunching : Not Downloading Any Work Units (Mac OS X) (Message 39218) Posted 10 Apr 2007 by Ai-Leng Post: More details on the situation. I am running projects for SETI and Einstein@Home. These projects are running okay, new work units are downloaded after old ones have been reported. This isn't the case with Rosetta@Home. This is the message log of the last work unit reported.

4) Message boards : Number crunching : Not Downloading Any Work Units (Mac OS X) (Message 39184) Posted 9 Apr 2007 by Ai-Leng Post: I'm using Mac OS X 10.4.9. I haven't seen my BOINC software download any new work units from Rosetta since finishing the last work unit. Though have to admit that I haven't been online for a few days due to the Easter holidays.
5) Message boards : Rosetta@home Science : 10 reasons I crunch R@H and you should too (Message 39036) Posted 5 Apr 2007 by Ai-Leng Post: My Reasons For Crunching Rosetta 10) It runs on Macs. 9) I choose how long work units run for as well as how much disk space I designate to the project. 8) I can contribute to the world of medical science by simply having my mac do some positive work while I'm away from it. 7) The screensaver starts conversations and even encourages others to join in. 6) It puts perspective in my life and I realise that I'm quite lucky to be healthy. 5) It would be great to have a cure for diseases and conditions that take loved ones from us leaving us to heal with time. 4) My cousin was diagnosed with cancer when he was 2 and a half years old. After bouts of chemotherapy, he has been given the all clear. Chemo isn't a kind treatment, to see it on a young child is heartbreaking. I'd never felt so helpless. 3) It's a fantastically warm community to be part of with communication between researchers, mods and volunteers. 2) It's free. 1) I can help save the world while being asleep. That's pretty nifty.
6) Message boards : Number crunching : Problems with Rosetta version 5.59 (Message 38970) Posted 4 Apr 2007 by Ai-Leng Post: Mags, if you happen to have a short runtime preference, and you crunching did not complete the first model, then what happend is just that the task never reached a checkpoint and the work up to that point is lost. This is why improved checkpointing is on the list for including in the next release. [edit]The other possibility is that you are seeing the 0% complete issue, even though the graphic shows models crunched and the total CPU time. I'm not positive if this issue that was observed on Ralph still existing in the 5.59 verison or not. This may be what Rhiju was referring to when he said sometimes at the beginning of the model the estimate can be "a little off". Even if that issue still exists, the tasks completed OK. It was just a bit confusing to monitor the % complete after powering down like that. You will find it increases quickly and will complete the task at the expected time. Basically, if a task is restarted, work begins from the last checkpoint, or the last completed model. And it begins with the amount of CPU time you had at the time of the model completion or checkpoint... but for some reason, BOINC is not reporting that total CPU time to Rosetta. It is only reporting the time since this restart. So anyway, this is a kink that needs to be worked out. But it's an issue that the Project Team is already aware of. The thing is, the total CPU time also resets to zero and continues to crunch. This same work unit is still being worked on as it hasn't been completed. I switched my Powerbook off again to come home from work and also during a fire drill at work. Will be leaving it on all night tonight for completion and reporting. Not sure if this additional information helps you at all.
7) Message boards : Number crunching : Problems with Rosetta version 5.59 (Message 38953) Posted 4 Apr 2007 by Ai-Leng Post: Well I was a one of the small number of people on a mac with issues with v5.54. Now, something odd has occurred. Boinc was crunching away data for s029__BOINC_SYMM_FOLD_AND_DOCK_RELAX-s029_-truncate_hom014__1638_3094_0 and everything was going well and had reached a progress of 95%. The next unit for Rosetta had even been downloaded ready to start once this one had finished. It was at this point that I switched my Powerbook off to head to work. When I started my Powerbook up again, I noticed that the Progress of the same work unit is 0% and the data processing has since restarted. I didn't see any error messages at the time of when I switched my mac back on.
8) Message boards : Number crunching : Problems with Rosetta version 5.54 (Message 38844) Posted 2 Apr 2007 by Ai-Leng Post: Hi, I'm not sure if it's here that I'm supposed to post this. The 1% thread that is active is a little hard to follow. I've been constantly getting Computation Errors in Rosetta Version 5.54. I'm running Mac OS X 10.4.9. I rarely got these with the previous version of Rosetta. The graphics have been running fine.
