I process 2 Help Defeat Cancer work units at a time but now one is stuck at 0% progress after 2 days running around the clock (and the computer isn't doing anything else). Should I abort it?, or something else?
I am using Boinc version 5.4.9. HDC 5.14 workunit B14641_0256_CTMA4A-17-8-15-c1_0 Windows XP SP2 pentium 4, 3GHZ 1014,07MB computer id:50218 |

Hello Richard de Jong,
Yes. But first send a 'Contact Us' report with all the information you just gave. This will make it easy for the staff to re-run the work unit trying to find a bug. Also, bring up Task Manager and try to see what is happening. Is one thread running and the other frozen? Are both threads sharing the processor? This sort of observation has proven helpful to Rick Alther in the past. Lawrence |

Hi Richard,
----------------------------------------A good rule of thumb, with BOINC, is to go to the Results Status pages, find the troublesome work unit in the list, click on the work unit name and see if anyone else in the quorum of 3 has returned the same WU and what the result was. If Pending Validation, the source of the problem becomes more obscure, if others had 'Error', than it's probably related to that specific job. If no-one has returned the unit yet, u could always suspend it and let another task start. Than check back later at the Result Status for an update. Running 2 Help Defeat Cancer simultaneous is heavy on a 1gb RAM system. Occasionally the models get very big (750-1,000mb) at which time u could see substantial disk swapping impairing actual use, but as u say the PC is only used for crunching, you're fine. Disk swapping adds to the wallclock crunch time!

Does BOINC show the process accumulating CPU time?
----------------------------------------Check the task manager and verify that some other process is not taking up the CPU. BOINC has been known to 'get lost' on occasion and not actually run a task that it says is running. The first thing I would do is exit out of BOINC and restart it and see if that gets it going again. The next thing to do, if it still appears stuck, is verify that it is accumulating CPU time and that the task manager shows that it is taking CPU. If it is, let it run for a while again. Make note of how much memory and VM it's taking up (you can select those columns from the 'View->Select Columns' menu in the Task Manager). If after a while it's still not progressing, make note of the work unit and use the 'Contact Us' link to send us the info: * Device id * workunit name * problem symptoms * Memory and VM utilization * Anything else you think might be of use: any Anti-Virus and Firewall software you are using, etc. After that, just abort the WU via the BOINC interface.
