Just giving ya crap brother.
LOL my letter that comes before r in the alphabet doesn't work on my laptop LOL
I did some tests to see how many wu's was the best for my system, a email@example.com and a 7970 at 1300mhz. I used the elapsed time in boinc, say 10 minutes, and went 60/10 = 6 tasks completed an hour. Then I multiplied that times the total number of wu's, say 10 wu's, for a total of 60 tasks completed an hour. The times are not perfectly exact. I did some rounding and not every task is completed in the same amount of time.
4 wu's 3.5 min 69 t/h
6 wu's 4.5 min 80 t/h
8 wu's 6 min 80 t/h
10 wu's 8.5 min 71 t/h
12 wu's 9.5 min 76 t/h
14 wu's 11 min 77 t/h
16 wu's 12.5 min 77 t/h
18 wu's 14.5 min 77 t/h
20 wu's 15 min 80 t/h
I find the dip at 10 wu's interesting, as I consistently got about 8.5 minutes from 20 tasks being completed. Also, my computer is perfectly usable up until 16 wu's.
i've had 70 Computational errrors from my GPU. HELP!
I get 6:30-7:30 with 10 WUs when they stagger after about 30-60 minutes because I have 8 threads to spread them out on, and they still hit my CPU at 100% when they reach their checkpoints. If there were such a thing as a dual LGA 1155 board I would gladly buy one to have my pair of 3770Ks going so I can feed my 7950. I don't know how you guys with 30 WUs going do it on 8-12 threads without running into a huge CPU bottleneck.
I only have 4 threads. Next year I am hoping I can get an i7 for cheap, as in $100. 2500k's can occasional be found now for that price.
I also tried to run a HD 5450 when the GPU WUs were still in beta, it was taking a lot of time to only finish 1 WU and they were all invalid... At the time I didn't find a way to make it works properly, but if I think about it I'll try again in 1 week and ½.
mine are failing in 1-2 seconds, not even attempting to run them :shadedshu
thank you anyway
HD 5450 is too slow to do anything with anyway. My HD 5650 in my laptop would take 10-12 minutes to do a unit and it has 5x the amount of shader cores.
I run 24 (2 x 7970) on 12 threads but they spread out nicely the most of the time. 30-36 as I think both t_ski and HammerON is doing on 12 threads could lead to some bottleneck I'm sure. I got a bigger problem with my slow 8 thread CPU that ran 10. I just reduced it to 9 since I kept getting one or two that would "never" complete.
Well it's sitting in the server doing nothing as secondary GPU. it estimates 20mins for each WU so it should be ok at it. Any tips to get it working. and NO buying a new one is not a solution
Forgive me if you said this earlier, but what OS? I know BOINC has some problems with Windows Server 2012 and possibly Server 2008 as well.
Yeah server 2008 r2 sp1, it is very possible :shadedshu
will try collatz to see
Edit: working fine on collatz
Yeah, Server 20xx is trouble and should be avoided for crunching from what I've heard. Even Windows 8 won't let me do more than one WU on my 7950 or the display driver crashes and kills the units. Had to go back to Wndows 7 which ended up being good timing after my SSD managed to erase itself after 3 weeks of use, but works absolutely fine now.
Crap, I had no solution to your problem Bo$$. Then I seen your running Server 08 r2. I also tried to run my GTX560 on my 4x4 system and got all errors as well. I guess I didn't realize you were running server 08 or I would have knew the reason for your errors. I apologize for not seeing that man.
It's fine, haven't updated my rig on the side
It's all fine now, the GPU's will do collatz now, no big deal
Thanks for that update Norton--everything look good again on all of my systems.
I'm going to try and set up two WUs each on the GTX470s--maybe it will do something interesting. Thanks for the info Buck!
I'm going out of town tomorrow morning-ish for my brother's wedding, and I won't be back til Sunday. I've decided to power down my PC while away, which means my crunching will be nothing for at least 2 full days. But while I'm down, it'll give me a little time to take care of a few cosmetic things I've needed to do on my PC arrangement. I'll check in on my phone while away, just to say hello
I'll be back Sunday and will have everything back up and running/crunching Plus, on Sunday I'll be throwing up a giveaway that NHKS and I have been working on for a little bit, as NHKS has snagged some great games to give out! Props to him
Dam, glad I upgraded my cruncher to win2k8 r2. Crunch and serve at the same time! Datacenter ain't bad. Hcc forever! Now on to my 1st mil....
so multiple GPU WU work for you?
Yep, using 7.0.44 64bit, crunching like a dam!
I wanted to "upgrade" from 7.0.28 to 7.0.44 on my 2x7970 rig since I still only had 600 WUs in the buffer. Big mistake. First I got the message that communication was delayed 24 hours. OK a restart might fix that. Nope, it was hanging at Win log-on. A hard restart lead to the option of repair or normal start but my keyboard was not responding so I had to go the repair route at time out but in order to start the process I need to use ENTER and that is not possible (keyboard works in bios). I tried to start up from my DVD drive but that don't work either as I ended the same place. For now I gave up and pulled one 7970 and replaced 2x7700 in another rig. In short I'm going to be down on points for some time. I could clone my working hard drive from a similar rig....
I'm sorry to hear about those troubles. Strangely enough, I've had no issues with 7.0.44--both running CPU WUs only on the Xeon DP and multiple GPU WUs on the GTX470s. Good luck fixing it!
manofthem, I hope the wedding goes great!
The Xeon DP setup is still crunching away--it's doing well IMO
Outages and repairs are going on over at WCG starting early next week....
Here's some links:
It's going to be a rough week next week
It may be time to consider loading up a few spare HDD's with an OS and the BOINC manager and loading them up with work before the outages so we won't run out of HCC work
That could be a solution
I cloned my one W3670 rig onto an old HD (was a SSD), detached WCG and added it again. No point in trying to run the same WU on two different rigs. This is not related to the Nortons post but was because my Windows collapsed. The downside is that my "so_close_to_10M" rig is now at 0 points. Anyway I'm now running my two 7970s in two different rigs and my 7700s are collecting dust. I want to see how much difference there is from running two-in-one to two-in-two.
