Hello,
I have a Intel Core 2 Duo E6600 with 2 gig memory. I also run Windows Vista Home premium (32 bits). At the moment boinc is busy with human proteome folding - phase 2 5.18 . The workunit is called le310_00019_15. Processor time: 09:41:18. Till completion: 04:40:01. Boinc version: 5.8.16. Has anyone got an explanation why this workunit takes so long? |

Both projects are long running. I had a FAAH go over 7 hours overnight on this AMD64 2.4 GHz. BOINC Benchmarks are useful for comparing relative computer speeds here.

Time to completion is a guess, and should become more accurate closer to the end, naturally. The techs are thinking about squeezing both projects to make some shorter workunits in the next few days. There's nothing definite, but they are trying to help until another faster project comes along. General concern: If you turn your computer off/on, work will resume at the last checkpoint. This one just sounds like a long workunit. What's going on in the other side of that Core 2 Duo? (just for comparison if there's another BOINC over there)

Hi, retsof,
Thanks for the reply. What do u mean with other side of core 2 duo? I run boinc using 80% of the cpu. Other projects I'm participating in: Rosetta@home Seti@home Climateprediction.net 16-7-2007 12:33:40||Benchmark results: 16-7-2007 12:33:40|| Number of CPUs: 2 16-7-2007 12:33:40|| 2225 floating point MIPS (Whetstone) per CPU 16-7-2007 12:33:40|| 3133 integer MIPS (Dhrystone) per CPU Bye |

WhiteLotusDragon,
What's going on in the other side of that Core 2 Duo? (just for comparison if there's another BOINC over there) I believe retsof was referring to what the other core of your C2D was running. Does BOINC show two processes running at the same time in the task window of the advanced screen? If so then each core of your C2D is running at 80% (which would actually look like 100% for 4 seconds, 0% for 1 second in task manager if I did my math right). 2GB of RAM should be more than enough. Maybe if the other processor is running a more memory intensive app, then there might be a lot of pagefile swaps going on in the background. Also the more applications you have open then the more CPU cycles (and memory for that matter) are going to them instead of BOINC as they take priority, that might make the project take a little longer to complete. |

WhiteLotusDragon, can you please check in the Tasks Tab of BOINCMgr, advanced view to see if CPU time is accumulating, BUT ALSO the Progress %. If latter not, you may have a looping HPF2 work unit that is somehow not able to get out and finish the step.
----------------------------------------If it is *Not* progressing, 1. record the CPU time done and % progress. 2. go to the Projects Tab, select WCG and in left margin Suspend WCG. 3. Wait 30 seconds, than Resume WCG. 4. Return to Tasks tab and watch CPU time and % Progress You may loose some CPU time and a little progress, but normally on resume the workunit completes properly. Now, Vista has issues with BOINC and UD agent or for that matter many programs, but if you have been completing work units without issue, continue as normal, else visit the Vista FAQ in the Start Here forum. Added: On the squeezing of work unit as retsof mentioned a member news post was just made today in relation to that: http://www.worldcommunitygrid.org/forums/wcg/printpost?post=116745

A Core 2 Duo shouldn't have problems running 2 BOINCs at once. The throttling could even be kicked up to 100% with little effect except improved finish time since the BOINC application runs at low priority. These computers here run at 100% 24/7, and if I'm doing something else, the BOINC backs down. The BOINC throttle ends up making things jump around anyway since it's not as smooth as it could be. Heat is usually only a problem with laptops or unless the fan gets excessively dusty. My newest computer cruncher even runs cooler overclocked than an older one does at stock speed.
----------------------------------------I was just trying to find out whether a BOINC in the other side could have been a faster running one. 2 BOINCs at once is usually only a problem in a HT/Hyperthread machine, which is only faking a dual core. In the nature of these projects, we occasionally get a batch of long running or short running workunits.

OK. He may be running multiple projects in both cores.
----------------------------------------Climateprediction.net can take several months to complete a workunit, so I'd still recommend kicking that throttle up to 100% CPU power so things can finish on time. I have found another situation when running multiple projects. If the switch is too often and are not left in memory, pieces can be rerun over and over. I had a problem like that in the old HPF1 when switching after 1 hour. I have my BOINC profile set to run at least 4 hours before switching projects.

Unless you shut down the computer, from 5.8 it should not be doing that for any project. It will continue to the next checkpoint!

Boinc is doing 2 projects at once, 99% of the time 2 different projects. Each core averages at 40% cpu load.
I have reset WCG and received another workunit. |

There was no need to do that WhiteLotusDragon. Project *reset* will have lost you all work in progress, where a *suspend* and *resume* would only have lost you the time of one step back to the last checkpoint of both work units.
