Hey there. I Installed The boinc software aout two weeks ago and all worked well until two days ago i noticed that he did not do work anymore. The task manager showed 0%. Only when I setted the boinc manager to work all the time it returned to 100%. So I reinstalled boinc and controlled and set equal all of my hosts preferences. Now, only climate prediction works but the model will take 759 hours before complishon and the second model 947 hours. My Einstein host works normal but all three other hosts do nothing. Seti is offline, but the rest? Is all this normal or should i use other preferences than 100 on each project? Also my pc crashes sometimes after returning from stand-by. I controlled the checked the temperature , but all seems to be normal. also the drivers are all up to date. I use a broadband networkconnection and use XP service pack 2, radeon 9200 intel penthium 4 2.60GHz, 512 Mb RAM

CPDN work unit are big so 759 hours is quite low if you are doing 2 models (or 2 projects) at a time. If it is only 1 model I might expect a 2.6G P4 to be faster.

I wonder if you were caught by the benchmark bug that leaves your CPU at 0%. Exiting and restarting BOINC or pausing and unpausing should get it started again. There is a 4.45b version of BOINC that should help avoid this happening again if you are interested.

See http://climateapps2.oucs.ox.ac.uk/cpdnboinc/forum_thread.php?id=2921

For each processor only 1 project should calculate at a time.

&gt;Thanks, i think this answered my question. I have two processors so I removed three hosts that are not doing any work, i'll see if this prevents it from crashing after returning from stand-by. My cpu is back up to 100% after reinstalling it the second time. And i already used version 4.45b, so maybe is this a new bug?

Oh. I wonder if it is probably a problem detecting when the computer is idle and can resume computations then. Do you have "Do work while computer is in use?" set to no?

Have you tried setting "Do work while computer is in use?" to yes ?

If that is unacceptable, the alternative of trying to remember to switch from suspend to run always and back again is a pain.

If it isn't that perhaps the power saving setting could be set differently to enable BOINC to keep running.

Lol, my completion time is is 1879 hours and it's done 1%, deadline 22/1/2006, I'm doing SETI and Einstien, each has 1/3rd, maybe if you altered your settings so CP has a larger percentage you'll lower the time, also alter how many processors are used, I've altered mine to 4 but as SETI is down, I don't know how or if that will make any difference.

2 processors cannot work on the same sulphur model. With a dual processor, the setting isn't going to make much difference. With a single processor, it isn't going to make any difference because it will only use 1. If you have hyperthreaded processor setting to use just 1 processor per actual CPU will speed up a single model but you loose the throughput benefit of working on 2 different models/projects.
