Dear All,
I'm still using the subj PC when "main" PC is occupied by children or wife :) but it's not doing any BOINC work most of time: 1/20/2007 1:19:12 PM||Allowing work fetch again. 1/20/2007 2:12:46 PM||Resuming round-robin CPU scheduling. 1/20/2007 8:35:31 PM|World Community Grid|Sending scheduler request to https://secure.worldcommunitygrid.org/boinc/wcg_cgi/fcgi 1/20/2007 8:35:31 PM|World Community Grid|Reason: To fetch work 1/20/2007 8:35:31 PM|World Community Grid|Requesting 34 seconds of new work 1/20/2007 8:35:36 PM|World Community Grid|Scheduler request succeeded 1/20/2007 8:35:36 PM|World Community Grid|Message from server: No work could be sent. 1/20/2007 8:35:36 PM|World Community Grid|Message from server: No work is available for Human Proteome Folding - Phase 2 1/20/2007 8:35:36 PM|World Community Grid|Message from server: Your computer has 383.41MB of memory, and a job requires 715.26MB 1/20/2007 8:35:36 PM|World Community Grid|Message from server: (won't finish in time) Computer on 86.1% of time, BOINC on 99.1% of that, this project gets 100.0% of that 1/20/2007 8:35:36 PM|World Community Grid|No work from project and computer makes a pause for next 12+ hours. But if you will update the project manually - then it will get new workunit. Some info about benchmarks: <p_vendor>GenuineIntel</p_vendor> <p_model>x86 Family 6 Model 8 Stepping 3 696MHz</p_model> <p_fpops>624701969.106738</p_fpops> <p_iops>1087197371.606810</p_iops> I've deselected some fat projects from this device profile, but left the "If there is no work available for my computer blablabla..." setting enabled Usually it takes about 24 hours to crunch away 1 FAAH WU but BOINC manager shows strange digits: CPU time: 22min Progress: 1.2% To Completion: 558 Hours So, I have to questions: 1. Why this strange 558 hours in "to completion" column 2. How to minimize idle time. thanks /A |

What do you mean, old dog? I am having no problems running 1-2 BOINC workunits per day on a PIII-500. It runs 24/7, though.
----------------------------------------Yes, HPF is one of the projects that requires more memory. Try Genome Comparison for best results. It has a very small footprint usable by little computers. I would still recommend running all of the time in the background, rather than just when someone isn't doing anything. It may not be getting many cycles, so BOINC guesses that it won't be done in time for the due date.

The long estimated completion times are most likely due to a long result duration correction factor. This can be found in client_state.xml
----------------------------------------Make sure Boinc is shut down completely before making any changes to the file. Also make a backup just in case of error. The value for your computer should not be higher than 2 and I would think it shouldn't be lower than 1. BoB [Edit 2 times, last edit by popandbob at Jan 21, 2007 7:22:40 AM] |

Like always the answer is yes and no…
It seems to me like a waste of energy to dedicate and old pc for crunching. it is better to donate it to a school or something. But, if you are using the pc anyway so do some crunching with it. I have three old dogs (If I may quote you…) PII 400 MMX!!! That I use as my DNS and file server (runs 24/7). PIII 550 Celeron (for my small kids) PIII 800 IBM laptop that I use as my music streamer (I found out that when i run it 55%cpu it does not even start the cpu fan!). I use BOINC and Thread Master and i have deselected HDC+FAA for those pc’s. they also keep my house nice and warm in the winter…  My 2 cents. cheers, dbmms |

The value for your computer should not be higher than 2 and I would think it shouldn't be lower than 1. BoB Editing the client_state.xml file is not a recommend method. The file is written and read by BOINC up to 10 times a second. 1 wrong bit and you can throw away the installation or are forced to do a project reset AND u might not even notice the corruption after running BOINC for a while. Better is to select the 'No New work' in the project tab and let the work in buffer run to zero, THAN do a project reset. The DCF will be set to 1.0000000. Be aware that a DCF will climb very fast. Switch your PC off for 12 hours a day and it will jump. Use your PC intensely and it will go way beyond 2.0, indicating that the benchmark calculates that a job can be done in say 2 CPU hours, but including actual up-time CPU efficiency, it will take 4 or 5 hours to do. @ooDav, Let an 8 hour job partially run e.g. 1 hour without reaching checkpoint, switch the PC off for a few days and the job will jump back to zero progress and the 1.2% after a while will extrapolate to values like 558 hours. Let it run for a while and it will come down. FAAH jobs will suffer that faith..... watch the Best Energy curve for a green line getting to the end and returning to the beginning and u know it has just check-pointed, which is a good point to switch off the machine, better put it in Hibernation and it will resume without a 'second' of loss. Search for the bolded words on the forum and explanation will come to u. oops, way to much again for a Sunday post... 3 cents. ketch u laeter

Than you all for your comments.
2retsof What do you mean, old dog?I am having no problems running 1-2 BOINC workunits per day on a PIII-500. It runs 24/7, though. I mean that maybe it's better to follow this advice dbmms: It seems to me like a waste of energy to dedicate and old pc for crunching. it is better to donate it to a school or something. and RIP&replace this laptop? Yes, this is a laptop and it's running BOINC service 24x7 during last several months. But it's doing very long pause in crunching after every successfull result. I have to manually update the project to get one more result. I will disable FAAH in profile and will see if it give me anything. |

ooDAV:
----------------------------------------It is always a tossup if the older PC's are worth doing the crunching. I have 3 PIII's and a PII. I run them exclusively on Genome Camparison because of its minmal requirements. FAAH would cause my best machine in this group to instantly reboot, so I disabled it even though it would meet the minimum requirements. All of these machines do well with the GC project. Their waste heat does help to warm my basement. 1.Intelx86 Family 6 Model 8 Stepping 6 930MHz PIII 2.Intelx86 Family 6 Model 8 Stepping 6 697MHz PIII 3.Intelx86 Family 6 Model 5 Stepping 2 397MHz PII 4.Intelx86 Family 6 Model 7 Stepping 3 498MHz PIII In short, I think it is worthwhile to use these for something good rather than relegating them to the scrap heap. The cost for the electricity is really not that great. Cheers Sgt.Joe Minnesota Crunchers

It seems to me like a waste of energy to dedicate and old pc for crunching. it is better to donate it to a school or something. Schools want fancy gaming computers and servers, with the $3500 in school property taxes they get each year just from me. The kids were knocking on our door last year running a fund drive for software that I didn't even have. THEY should donate THEIR old computers to ME.There are still places for old computers. Goodwill computer works in Austin takes donated computers and parts, gives jobs to disabled people to put them together, and sells refurbished systems to poor taxpayers. They also have a computer museum containing REALLY old computers....Trash-80s, Commodore PETs, and before.

(maching is running 24x7 for a while) I've followed your advice and now it works normally. Thank you! |
