21) Message boards : News : started a new search called 'ps_separation_10_2s_sample_2' (Message 54914) Posted 26 Jun 2012 by Ray_GTI-R Post: So Matt Arsenault is telling me that the ATI 0.82 is deprecated and you should be using the newer OpenCL version. Not possible on an ATI HD3850, it has no OpenCL support. Just processed 6 'ps_separation_10_2s_sample_2' tasks quite happily on my HD3850. O/S is XP SP3 (32-bit). I wonder if my earlier message on a different thread simply didn't get through. I'll try again here:- HD3850 XP SP3 (32-bit) works. HD3850 W7 SP1 (64-bit) failed.

W7 64-bit/HD3850 AGP & existing MW@H GPU tasks ALL fail with "Computation error" whereas ... XP 32-bit/HD3850 AGP & existing MW@H GPU tasks work OK. All SETI/Catalyst/etc the same on the same hardware. What are your thoughts?

I use ATI Tray Tools rather than BOINC settings. With ATI Tray Tools I can:- a) set a custom fan profile (the fan profile in the standard driver had a major flaw) b) set a custom VDDC (I'm currently running one HD3850 at 0.975V at full speed and a "problem", hot-running HD3850 at 1.014V) rather than the standard 1.254V c) set the GPU & memory speeds (to +/- 2mhz. The "problem" HD3850 has a GPU speed set to 567mhz rather than the 669mhz standard & memory at full speed) With ATI Tray tools set as above these cards do not exceed 55C at +/- 100% load, fan @ 60% max with lots of fresh, filtered airflow. OK, it's a cool summer here in the UK - overnight ambient 16.6C & breezy :-) Why? Hot=inefficient=more current IIRC. Sorry, no idea why 0.82 is better than 1.02 by 78W/0.65A @ 119V AC

Exactly the point I have been trying to make for a couple of weeks. And exactly why I did the latest exercise just to prove it's not hardware. Specifically, it's new MW@H tasks. Older MW@H tasks worked fine on the same hardware & W7 64-bit:- see my earlier posts which explain it all. I use a 3850 AGP on WinXP32. (only to let ya know it is not 64bit only). dskagcommunity ... looking back on your posts they are different from the errors I got. Compare my working BOINC version/driver deails posted earlier with yours. Also worth checking that all .NET updates are, erm, up to date and flush old tasks then try the latest ... at various points in the past couple of weeks there have been a few false starts with generating new WU's that work.

Replaced Windows 7 SP1 (64-bit) with XP SP3 (32-bit) - so, same hardware. All .NET/drivers/updates/BOINC reinstalled (see previous post for details). Since last night I have downloaded fresh new WUs and processed over 70 GPU tasks OK (one fail, probably a fluke during update of .NET). So ... W7 64-bit/HD3850 AGP & existing MW@H GPU tasks ALL fail with "Computation error" whereas ... XP 32-bit/HD3850 AGP & existing MW@H GPU tasks work OK. What do you reckon?

That was a CPU task not a GPU task. :blush:

PS:- Collatz still happily crunching brand new* GPU tasks using the same "old version of your ATI application". *downloaded from 9pm today (2nd June). As I said, nothing new here aside from the latest MW@H GPU tasks consistently failing.
34) Message boards : News : testing work generation with 'ps_separation_14_2s_null_3' (Message 54630) Posted 2 Jun 2012 by Ray_GTI-R Post: To recap:- on my PCs ... The current batch(es) of GPU WUs fail. The previous batches ran sucessfully. Others report the same issue. There has been no ATI application/driver change at this end. I thought the only change was to create new work i.e., I'm testing work generation right now, there should be workunits available to download now. Let me know how these workunits are crunching! Matt A. says it's because of the old version of your ATI application. Has there been an unannounced update to MW@H crunching requirement(s)?

PC #B is 231173 (all old tasks complete OK, no new tasks for days as switched off). Can you point me to where you see PC #A (446288, post- 1st June, about 22:00 UTC) succeed processing any but that one [old] GPU task? Apologies if I've got any of this wrong. I'm not an expert, just a cruncher.

PC #A Just completed a ps_separation_09 task, OK All else fails with computation eror at 100% completion:- ps_separation_14_2s_null_3_v2, v3, v4, ps_separation_14_2s_05_03 I have restarted, cold booted and detached/reattached. Same problem as above. Result:- Will suspend project and abort existing ps_separation_14 tasks until a fix is in place. PC #B (only now switched it on after a couple of days, so no recent tasks have been loaded yet) Completing ps_separation_09 tasks (7 of them so far), OK Result:- I've switched to "No new tasks" for now. For those with headless/unattended servers, you're going to either be busy for a while or else waste a lot of electricity doing nothing until a fix is found.
