	It's broken. My first Astropulse 6 completed after 20 seconds. I want a refund. >:o( That was a B3_P1 AP. Those have a problem and are about 98% of the time 100% blanked. Take a look at the taskID for it and you'll see: In ap_remove_radar.cpp: get_indices_to_randomize: num_ffts_forecast < 100.

	Small discrepancy in different ReadMe files Here: http://lunatics.kwsn.net/index.php?module=Downloads;sa=dlview;id=328 http://lunatics.kwsn.net/downloads/Lunatics%20ReadMev0.40.txt "You will usually find that the SSSE3x application is fastest on the Intel processors which support SSSE3x, except on dual-core CPUs with especially fast memory subsystems." Somehow the last part was deleted (Or not added initially? "Lunatics ReadMe.txt" found back in Lunatics_Win??_v0.38_setup.exe have the same omission). In other places (ReleaseNotes.txt, first post here) the sentence is: "You will usually find that the SSSE3x application is fastest on the Intel processors which support SSSE3x, except on dual-core CPUs with especially fast memory subsystems, where SSE4.1 may be faster." ____________ - ALF - "Find out what you don't do well ..... then don't do it!" :)

	I installed v0.40 on this pc and initially it went well, but after about 20 Cuda tasks I noticed a sharp drop in processing rate. MSI Afterburner tells me the GPU load of only 2% with an occasional peak to 90%. I run 2 tasks at the same time on this 560Ti and the normal GPU load is 95-97%. The result files (stderr output) do not show any information that indicates a problem. What can I do to solve this? ____________ Seti@Netherlands website

	I went back to Lunatics_x38g_win32_cuda32.exe (only exchanged the Cuda executable and modified app_info accordingly) and it runs ok now. Looked at most of the tasks finished today on this host and around 10-15% of these tasks took 10x the usual time. The usual time for a 2.7 AR task is 3 minutes, now some of them took 1800-3200 seconds.

I'm too tired... 560Ti? They are known to cause trouble with later x-branch, when they start getting pushed. jason has a post somewhere that lists about a dozen things you can check... ____________ I'm not the Pope.

There's a link in the first post - host ID 5907499, driver 275.33 I'm trying to remember the history of x41g and 560Ti cards - I may need to do some digging. I think we had some early reports that some early samples of the 560Ti weren't being supplied with enough voltage to support the increased optimisation (equals workload) of x41g.

I think we had some early reports that some early samples of the 560Ti weren't being supplied with enough voltage to support the increased optimisation (equals workload) of x41g. Looked through and spotted some long running shorties. There are major things to check with 560ti: - sufficient core voltage such that it doesn't downclock (couldn't see evidence of downclock online, but possible) - Running a solid state drive ? Make really sure its firmware is up to date... then check again. ( Yes this causes problems with Cuda apps due to broken SSDs hogging DMA, that was a real toughy to find ) - Update driver using the "clean Install" Advanced Option - [Check temperatures] x41g pushes harder. - running other projects with non-threadsafe Cuda apps ? - If you run into those long runners, check the file sizes on those tasks... Could be a reappearance of those freaked out tasks, or corruption during download of some sort Jason ____________ "It is not the strongest of the species that survives, nor the most intelligent that survives.

	- If you run into those long runners, check the file sizes on those tasks... Could be a reappearance of those freaked out tasks, or corruption during download of some sort Jason The mega-WUs only caused an extended delay at startup, while the coded receiver data was re-assembled using the CPU. Once the task got into its stride, the CUDA part ran at normal speed. Any other workunit corruption would have caused an error, not a slowdown - like an MD5 error, of a filesize mismatch during download, I'd have thought.

Just trying to list as many options to cover as I can recall. The 560ti were also originally sold with some crackpot drivers ( 266.66) that messed up a hidden Cuda kernel compute cache if they were ever installed, though doesn't look like the problem here. I'm wagering on the other project, or SSD issues until we hear more back from the OP [Edit:] While I'm asleep, If the OP eliminates those possiilities & still has trouble, I'd like yourself or other Lunatics crew to trial the x41u Cuda 4.1 build on the same machine if possible with the OP (would need attention to driver version etc). I'm in the process of cosmetic cleanups, mostly Kepler related, and intend to release after this AP 6.01 transition dust has settled anyway. x41g should work just as well as x38g on that card really, but x41u Cuda 4.1 is in a different league on 560ti.

The 560Ti never showed any sign of downclocking. MSI Afterburner confirmed that nothing happened with the clockrates. 2. No SSD 3. Will update the driver and let you know the result. 4. As you can see in the Afterburner screenshot, the temperature was 60°C. Now with x38g running, the temperature is 70°C at 63% fan speed 5. No other Cuda apps were running One other thing I should mention: prior to installing v0.40 I updated Boinc from 6.10.58 to the current 6.12.34.

Well we'll find out one way or another. With those things eliminated, if after updating driver you still get weirdness, we will get you testing x41u. Can't very well push out an updated release next week if there is some unknown latent problem lurking. Thanks for the cross-checking.

	If either John van Gorsel or Victor is game to try out the experimental x41u version, please PM me. I have them here ready to email (tell me your email address), or if you prefer I can find a hosting site for you to download from.

	So just to confirm, when I get to this, which may be a week from now, i7-2 will be fastest with SSE3 correct? Or should I try SSSE4.x as it's a i7-2?
