Topic 190426

i just started in this project and have been running an einstein@home project for about 3 days. i have a celeron 2.66GHz with 1GByte of memory. according to winXP's task manager, the einstein exec has a cpu time of 63:13:29 while boinc indicates a cpu time of 3:27:09

at the rate that boinc is indicating in cpu time, this exec will not be done for several weeks!!

Bill,

Do you have Einstein set to "do work only when cpu is idle"? It defines "idle" as when the mouse and keyboard are not being used. When another cpu-intensive program is running, Einstein only gets leftover cycles, and it's time reflects how much of the cpu it gets, not clocktime. Also, if you have set it to restricted hours to work, it will be "running" in the Task Manager, bot not allowed to do anything.

Michael,

my preferences were set to "do work only when cpu is idle", last night i set it to "always work". i left the computer running all night. about the only process that ran was my anti-virus full scan. i do not have it set to restricted hours. over last night, boinc indicated only about a 1/2 hour of work, while the task manager indicated that the process ran all night, 24 hours. it appears that after about 1/2 after i stop using my machine, boinc stops working. i do have the system shut off the monitor and shut off the disk drives after 1/2 hour of inactivity. could this cause the problem??

thanks,

bill

I bellieve I saw on one of the forums that you need to leave your disk drives powered up. Turning off the monitor isn't a problem tho. Also, sometimes there are problems with AV programs making BOINC think that the computer is busy all the time.

I recently returned after

I recently returned after about 3 or 4 years away, from the days when SETI was the only saloon in town, and found all these goodies to play with and settled on SETI, Einstein and Climate on my spiffing new 2GHz 750 RAM P4 with XPsp2 to replace my old 0.25 Hz 2 byte ram coal fired monstrosity. To my amazement all 3 progs seemed to be running much slower than they should, one second of work taking 12 real seconds or so.

No amount of fiddling and constructive obscenity improved matters, all the settings were correct (run when not idle, etc.) and I was at the point of thinking that it would be quicker to work it all out on paper with a pencil when for other whimsical reasons I Formatted my C:\\drive which holds windows and almost nothing else, leaving Seti et al. on the D:\\ which is my mega whopper program and data drive. When I reloaded XP and set it to work, all 3 programs started whizzing through at over the speed of light, giving Einstein severe indigestion and crunching away like a dream, and things remain just so since. What does all this mean? Why did reloading Windows fix everything?

Did you ever defragment your disk? I am a Linux user, but sometimes I use WIN98SE to fly on my favourite airplanes and I know the difference in performance between a fragmented and a defragmented disk.

Kit,

We tend to "fiddle" with our computers, adding programs, uninstalling same, changing AV apps, adding lots of little utilities for this or that. Some of us often do not uninstall them correctly or the uninstaller does not thoroughly remove many things, often leaving folders behind and nearly always leaving unnecessary .dlls (or worse, altered .dll files) in Windows. Too often (and this is a real biggie) many actually have two or more AV programs running, and that causes major conflicts with file permissons. Another biggie is virii, trojans, spyware, and assorted other malware that sneaks crap into Windows. All of the above can severely sap Windows running efficiency.

Another thing is the incremental Windows updates, between Service Packs. These incrementals are nearly always later included in the SPs, and get dropped in twice, in slightly different versions. By formatting and re-installing Windows and Sps, and then just adding only the remaining updates, you've somewhat streamlined your windows installation, making it much more efficient.

Note: It is possible to go overboard by formatting and re-installing too often, even to the point of running up against Microsoft's limit on re-installs, in which case you'll not be allowed another re-install! At any rate, it's a great PITA to have to re-install all the other software after redoing Windows.

Others may add to this info but it goes a long way toward explaining your new-found speed.

When I started running E@H on

When I started running E@H on a laptop, the computer would shut down after about an hour. I put the laptop on a homemade cooler and it's been running 24/7 without any problems for 3 weeks.

No, I have a defragmenter that works all the time, theoretically and to my surprise seems to do a very good job.

Nothing. The schedule makes decisions based on debt and time. If a single processor, only one will run at a time. If dual core or HT, 2 results will crunch, but you can not force one of each. Sometimes both of one or the other will run.

Each project uses the maximum amount of CPU, so sharing 50-50 only means time, not splitting the processor. Since these are high end calculations your FPU is really loaded with the single processing result.
