I just thought I'd see whether an old machine can do some crunching, so gave it a HPF2 WU. It got aborted about 95% of the way through with "exceeded CPU time limit 310817.808529".
I must admit that I reckon having 11 day time limits on WUs and killing them after 3.5 days is stupid, but is there at least somewhere that the maximums are listed? |

Hello Kremmen,
No, this limit is supposed to catch endless loops and is set in the work unit by the techs. Looks like HPF2 won't do. Why not try FAAH or DDDT? Lawrence |

Why not try FAAH or DDDT? Because they use almost twice as much RAM and the consequent swapping would make them run much longer, so I'd expect them to do worse. |

what are the specs on the pc as i have a few pentiun pros running they seem to be doing fine....but they also have plenty of memmory...

It's very probable Kremmen ran into the endless looping bug which is the only plausible explanation why running into the time exceed function. The workings are that a jobs of any project has the running current average flops in the header from which the device computes estimated time. In case of HPF2 that must have been exceeded by factor 6, which is the cut-off for this project.
----------------------------------------Had one nearly myself yesterday before the eye caught a folding job running for 14 hours and at 48% when the machine normally does them in 4 to 5 hours. A suspend WCG (project tab!) and resume kicked it back to 1:50 hours and 44%. 12 hours lost in space. I'll be updating the 'project matrix' in the website support forum shortly as noted that some of them changed their low/hi for ram and VM. FAAH is now on VM up to 360mb and HPF2 is down to 49mb lowest and 119.2 highest on RAM (BOINC) and 204mb on UD. Not for nothing does WCG set conservative minima for the eventualities on the System Requirement page.

In case of HPF2 that must have been exceeded by factor 6, which is the cut-off for this project. No, it's not the only plausible explanation. Current CPU time/fraction done was consistently around 350,000 and looked to be on track for that all the time. However, "estimated CPU time remaining" started at around 100,000, which was quite silly. The calculation of estimated time is often totally wrong. It seems pretty obvious that the likely time remaining should be current CPU time/fraction done. However, in the case of the software being moved from one piece of hardware to another, the software appears to come up with a totally bogus number. Maybe it's remembering irrelevant data from the previous machine somewhere instead of taking the current calculation as it should? **Edited for improper language TKH** [Edit 1 times, last edit by TKH at Dec 17, 2007 4:19:36 PM] |

Ah, well i wrote 'very probable' and never said 'only', and now reading you moved the install from one device to another, nothing surprises me in estimates being wrong. A project reset or detach/reattach and a forced benchmark would set most parms immediately right.
----------------------------------------And please do sanitize your post as else the admin will put the 'nelsoc' mark on. cheers

A project reset or detach/reattach and a forced benchmark would set most parms immediately right. It seems confused about the duration_correction_factor. As for being killed for using too much CPU time, I just disconnected it from the net for the last day so it wouldn't be able to contact the server. :) And please do sanitize your post as else the admin will put the 'nelsoc' mark on. Sorry, but that's just lame. Australian broadcast rules used to ban 4 words, but they're now down to one. (The "c" word.) I've uttered none of the 4. If you're going to "sanitize" innocuous slang then, by all means, knock yourselves out, but I'll ignore any suggestions that I stoop to that pathetic level. |
