My win 8 box was borking tasks so I rebooted into linux and all is fine now except my daughter won't be able to play SIMS for a few days. ;)

Yeah, HT is definitely not worth it. I was thinking the huge L3 cache may have helped with that, but guess not for LLR. What clock speed is yours set at? Mine is currently at 4GHz and I am just barely under 30K seconds per WU.


3.8 GHz w/ all 4 RAM slots occupied (quad-channel mode) and RAM is DDR3 1600 MHz 9-9-9-27-2T and running at that rated speed and timings. This is from memory since I'm in linux and would have to boot into bios to confirm.

Hmm, I have all 8 slots occupied with quad channel memory, but I think its speed is at 1333 MHz. I should try increasing that.


My mistake, I have all 8 slots occupied too. So memory speed is important for this project. Would there be a difference in quad channel vs dual channel?

I have a 3930K also, and I am interested in your results here. What are your results comparing HT with not HT?


In linux, 28,000-30.000 seconds with HT off and 58,000-62,000 seconds with HT on.
In Win 8 with HT on, ~55,000-58,000 sec.

Not a big difference, if any, I think.

My 15 minutes of BOINC fame are ending. Fun graph to see. But I am very glad it is working itself out.

Is there any idea when the host issue may be resolved?

If you install BOINC client version 7.0.36, your problem should resolve on Windows 8.


I'm not sure it's that simple. I was running win 8 pro 64-bit with 64-bit 7.0.36 and with last check, 40+ WUs have been validated. I decided to test WU crunch time with HT turned off (3930K processor). I rebooted into bios, turned HT off and booted into win 8. I had 12 WUs going at various stages of completion before the reboot and 7 of them completed normally with HT off. As soon as a new WU started, I saw the same thing that Adam is experiencing. 3.xx seconds WU time and 0.00 CPU time on about 7 WUs before I stopped fetching new WUs. I don't have an explanation for this but I did reboot back into linux (OpenSuse 12.2, 64-bit) and WUs have been completing and validating with or without HT. The other thing I noticed was that win 8 completed the WUs about 5-10% faster than OpenSuse. Anyone else seen this?

I am curious if maybe Windows 8 has a potential issue similar to one in Linux where the 64-bit versions do not have the 32-bit libraries by default? Maybe 3 seconds or so for the wrapper to start in Windows and then crash when 32-bit libraries aren't there?



My windows 8 pro (64-bit) was a clean install and I didn't see an option for installing 32-bit libraries. I then installed the 64-bit version of BOINC 7.0.36. I do see the wrapper running (once instance per logical core) and all are labeled as 32-bit processes (task manager) along with other 32-bit apps including chrome. The boinc manager, client and primegrid_cllr.exe all appear to be 64-bit processes as expected, correct? So based on the above, it appears the 32-bit libraries are installed by default on 64-bit windows 8.

I have a Win8 box too http://www.primegrid.com/results.php?hostid=299960&offset=0&show_names=0&state=0&appid=7, but the results need 37,000 seconds, not 3!

3 of the 5 top users of this challenge are wasting WU's as you can see here:
http://www.primegrid.com/workunit.php?wuid=307673318 :-((


And they all have windows 8 in common.


Your windows machine runs BOINC Client 7.0.36

aegelhof,
Adam,
jonmarlow
all 3 have Win 8 x64 like you but they all run BOINC Client 7.0.28 and they all are at the top with hundreds of failed work units (Adam has no successful ones at all).

Could this be the problem, the BOINC Client version?


It could be. A member of our team is a boinc alpha tester and he strongly recommended running 7.0.36 on Win8 until something better comes along. I have one rig running win8 & 7.0.36 in the race and it seems to be OK although a few of the results are marked "validation inconclusive" but in those cases my wingman is one of those computers with 3.x seconds runtime and 0.0 seconds CPU time. Here's a link to my rig running win8/7.0.36 http://www.primegrid.com/results.php?hostid=298696
