1) Message boards : Number crunching : MW's WUs crunched at lower priority. (Message 26209)
Posted 22 Jun 2009 by frigens
Post:
I've just noticed that BOINC (v36.6.36) run MW's WU at the lowest priority on my i7 965 system. I've Cosmology and Einstein attached on this machine. BOINC always give priority to the two other projects and only occasionally start MW's WUs. I've set the resource for MW to be 50% no significant change. I sometime have to suspend one of the other project to at least get BOINC to look at MW. Is this potentially a problem with v6.6.36?

It's just a problem with BOINC and the debt system it uses. Try increasing the MW resource share - or down grade to a non 6.6.x version of BOINC. I'm using 6.4.5 with MW at 50% and BOINC just keeps enough work cached for it but at least it is always trying to crunch MW. Some others have downgraded all the wasy to 5.10.45.



I tried BOINC 6.4.5 and it works ok, at least it's trying to crunch MW but after a day of work, BOINC started to download WU for the other projects and no longer request tasks for MW. I've to suspend all other projects to get BOINC to download MW's WUs again. Should I try a different BOINC version?

Thanks Gas Giant, let me give it a try.

Is it possible if I add 3870 card into my current 4870 system? I know that they cannot be used to CrossFire each other but what about using dummy plug or monitor?

_3s WUs still get compute error. When BOINC client start to crunch a _3s WU, the GPU app stop crunching any other WU indefinitely (GPU time move but progress remain at 0%). I'll have to suspend all _3s in the list, close BOINC and restart to get GPU app to work on _2s WUs.

Also, after installation of 019f, my quad system will run only 2 other CPU WUs plus 2 GPU WUs or 4 CPU WUs and no GPU task. I'm using BOINC 6.6.36 on W7 and catalyst v9.5. This catalyst package install atical...64.dll files on my system and I make a copy and rename them to amdcal...64.dll and place them back on system32 folder, will this be sufficient?

After having a look to your host list (the Win7 hosts), the only compute errors showing up on your computers are caused by using the old 0.19e version. The Core2Quad still runs 0.19e. After you updated the Core2Duo to 0.19f, all appears to be okay. And if you specify the options "n2 w1.1 f20" on that C2D, you don't have to wonder why 2 WUs run. But that is competely okay as running more won't help the performance.

And why the BOINC-Client 6.6.36 is not starting the GPU tasks in parallel to CPU tasks, I simply don't now. You can play around with the avg_ncpu value in the app_info.xml or raise the number of processed WUs in the c_config.xml. I'm using the client version 5.5.45, 6.2.19 and 6.6.21 and it runs quite okay there.

my Core2Quad host running W7 is currently using application version 0.19f not the old 0.19e application. the problem that I can see now is that BOINC client will stop processing MW WU when it run into problem. I'd have to manually closed down BOINC and restart it again to render the WU which was computed into error and the new WUs can then be progressed. I don't know why it show that I am using the old app version 0.19e but I'll try to wipe it out and reset the project again.

I can tell I am taking this all too seriously now and I refuse to buy any more of these Guppie cards. Dam things need PCs which clutter up my garage. I have a lizard to put on ice. Laters gators.




Me either perhaps I should turn off all of my computer and see how many $$$ I can save while waiting for WUs, perhaps that will add up for my new 4890 ;-P.

Ok, well I'm dummy enough for not knowing how this script works or how can I utilised that. Personally I don't want to bombard server with loop requests but I just think there must be a way to fix this, perhaps WUs quota? I admitted that I get some negative feeling when certain peoples get tonnes while the rest barely get anything.

While I understand the WU shortage situation at MW@H but I'm wondering, why some users can get, probably (based on RAC), >1000 WUs while most of the users here get next to nothing?

This computer (as well as other computers this user has) seems to have no problem getting WUs at all. Does MW@H project has preferred list of users who would get more WUs?

Ah yeah. I mis-remembered this ATi webpage.


ahh well there is always a limitation.

I have just upgraded a graphic card on one of my system from ATI3870 to NVIDIA GTX295. NVIDIA and ATI don't work along well so I'm taking ATI3870 off and have it back in the book. I'm currently crunching MW@H on another machine with ATI4870. Wondering if there is any good to add that 3870 card into this system? I've heard that we cannot crossfire 4870 with 3870 but will it help 4870 crunchs MW@H?
