Is it just me or is the cuda 4.2 WUs 30-40 percent faster than the 3.1s are. | |

Is it just me or is the cuda 4.2 WUs 30-40 percent faster than the 3.1s are. It's much faster on every host. It seems amazing the difference is so extreme. It is amazing, but it will vary among different wourkunits. Also, is it a good time now to get a 680 ? now that the project will support it ?? Definitely! | |

every host? i still get app 3.1 wus on the 285gtx O.o is it because cc1.3? or must i reattach? | |

The improvement is very noticeable on the normal length tasks, and certainly more than the expected 15% improvement. However it does vary considerably, from task to task!

Or a problem in some Linux driver packages? | |

Switched to cuda4.2 units for today.... so far 2 completed units and 3 have failed exit code - 98 (0x62) | |

If you updated the driver after starting a task, that task will probably fail. | |

If you updated the driver after starting a task, that task will probably fail. Been running the updated driver for a couple of weeks and 3.1 tasks (long) have been running ok. Now had 6 failures and 2 completed. My crunchers will be going offline whilst I jet off for a family holiday. Will see how things run when I get back. | |

Now had 6 failures and 2 completed. The CUDA4.2 failures could be caused by overclocking adjusted for CUDA3.1 tasks. My GTX 480s need 25mV more for crunching CUDA4.2 tasks without failures, also my GTX 590s had to be set to 625MHz instead of 725MHz (I don't want to raise their voltage). | |

Hi, I reinstalled the Nvidia 295.59 driver without problem, the OS works perfectly and the GTX295 is two tasks normally CUDA 3.1.ACEMD2 | |

Now had 6 failures and 2 completed. Will try fiddling around with settings when I return from holiday. If the long queue is switching to CUDA4.2 I'll try and get the cruncher stable on shorties first. | |

I still have errors in CUDA 4.2, Nvidia driver 302.17 installed new, not GTX295 OC. | |

No one answered me for some days now, hope it was only a overreading ^^ Are the cuda 42 apps only for fermi&kepler, because i get only cuda31 apps (yes i tested short WUs) on my 285gtx or must i reattach this machine? (what i must time right because its a unattended machine) | |
ID: 25772 | Rating: 0 | rate: / Reply Quote | |
You're running driver: 301.42, so this shouldn't be an issue. Maybe you selected one the queue which doesn't have the new app yet? | |

4.2 CUDA tasks keep getting error on my GTX295 Linux. | |

I tried both long and short. So this shouldnt the problem. But ok it seems there are still some probs with cuda 42 apps when i read the threads and i need valid results not wasting time :) only wanted to try one if it works or not as info for the team. | |

Should we migrate our Fermi cards to Cuda 4.2 compliant drivers? What drivers are required? Do we have a new recommendation on the driver version to be used? | |

Should we migrate our Fermi cards to Cuda 4.2 compliant drivers? What drivers are required? Do we have a new recommendation on the driver version to be used? Yes, if you can. The 4.2 app is fast. The latest drivers (301 series) are fine. Matt | |

No, I had problems with my GTX570 SC card. More from the office. | |
ID: 25803 | Rating: 0 | rate: / Reply Quote | |
Does the card feature a substantial factory-OC and is failing some tasks with 4.2? It has been observed that the new app is somewhat less tolerant to overclocking, or demands higherstability - however you want to look at it. | |

No, I had problems with my GTX570 SC card. More from the office. Sorry I have not written during the day. I transferred my GTX 570 SC to another computer to make room for my GTX670 SC in my most potent PC. At the same time I did up-date drivers on both computers to 301.42. All short work units Cuda 42 work well on both systems. However when I have attached the computer with the GTX 570 SC card to the long work queue, this long work unites (Cuda 31) failed. Means the computer shuts down randomly. I was able to restart computer as well as continuo the work unites, but the computer shuts down again after half an hour or so. The GTX 570 SC card worked very well short and long work units with Driver 275.33 on the computer, which has actually the GTX 670. The GTX 570 SC card works actually well with Primegrid Genefer (cuda32_13) and PPS (Sieve) (cuda23), as well with Einstein (BRP4cuda32nv301), so it is not the Cuda version. The video cards are factory overclocked. I have only modified the fan speed, so the temperature of the cards is below 70º C. | |

I only see two workunits which have failed with energies have become nan. Maybe increase the voltage slightly and see if this helps stability? Or of energy usage is a concern you could try underclocking it as well. | |

I recently had some issues with work units causing the computer to hang or freeze. The only way to clear the condition was a reset of the computer (or power cycle). It happened a couple of times to one of my systems that never has issues. I did not change drivers or any of the OC settings on the system. I assumed it was a couple of bad work units. | |

Paul i had/have that too with some nathans rps ( perhaps it was nathan too in your case??) at the time, some units freeze the machine in a special way. Desktop with no icons but windows is running. Often @ the beginning of a new computation while he uploads the finished wu. Good to hear they are the wus perhaps but itcomputes to finishing line after reboot. Strange. Changed fan to manual to bring it from 90 to 80 degrees. Will see how it works over weekend bacause this is litle annoing on a unaatended machine. | |

Probably haven't made the apps threadsafe which is why you need to reboot the machine. I know Richard asked the same question back in March but never got a reply. See this message Edit: Found the original message with code snippets here Maybe GDF or one of the other developers can confirm Acemd 6.16 (cuda42) does use the above logic (ie its threadsafe) ____________ BOINC blog | |

Wow - 90 is hot! I flashed my EVGA GTX cards with the newest BIOS and it unlocks the fans to 100%. I have them set at 90% at 70C and my 580s are down to 72C - 74C | |

Or of energy usage is a concern you could try underclocking it as well. As I have said, the problems are only with the cuda 31 app, not with cuda 42. In the night the computer failed with two cuda 31 apps. The strange thing: When I restarted the computer again, blue screen with warning message and the GPUGRID project was detached afterwards, so I attached anew and got one new work unit with cuda 42. Hope this works out just fine. The other two are just lost, and won´t be finished ever. Side note: I am running malariacontrol.net at all computers at the moment and this writes heavily on hard disks, so this might also cause the observed problems. Also my co-workers experience problems with this project, whereas with climateprediction,net - my normal CPU load - I normally do not have problems. | |

The CPU tasks may be the source of some of your problems. | |
ID: 25826 | Rating: 0 | rate: / Reply Quote | |
Yes it might be that the CPU task cause the problems. Unfortunately my computer knowledge is very limited, so what goes behind Boinc Manager, will have to be explained step by step. So I will be able to try it on my own, which I would be willing to do. | |

When you reattached to the project you lost any GPU tasks that were running. These must just appear as 'Aborted by user'. | |

When you reattached to the project you lost any GPU tasks that were running. These must just appear as 'Aborted by user'. No, I reattached once. It is: Task 5522912 and Task 5522851. Both are still marked in Progress on GPUGRID Homepage. But are not mentioned any more in Boinc Manager. | |

Should i have something besides boinc 7.0.25 and 301.42 drivers to get cuda 4.2 tasks | |
ID: 25844 | Rating: 0 | rate: / Reply Quote | |
Currently the CUDA 4.2 app is only being used for the Standard WUs and it looks like you are only processing the Longs. Hopefully GDF will release it next week? for the Longs also. | |

Should i have something besides boinc 7.0.25 and 301.42 drivers to get cuda 4.2 tasks I have the same problem ^^ Hope somebody tells us if we need to reattach or something ^^ (an nooo i tried short/standart units and it worked on a fermi card, only not on the 285gtx) I must wait until a WU is finished AND im in the room where the machine is, then i will try a reattach, could need a few days :) ____________ DSKAG Austria Research Team: http://www.research.dskag.at | |

Should i have something besides boinc 7.0.25 and 301.42 drivers to get cuda 4.2 tasks Detach/reattach wouldn't help. My understanding is they are only giving cuda42 to compute capability 2 or higher cards. The gtx285 is only a compute capability of 1.3 ____________ BOINC blog | |

Eight CUDA 4.2 long apps completed. Zero errors so far on my gtx570's. Seem to be 30-40% faster than like pointed CUDA 3.1 work done previously. I made no changes since updating drivers to 301.42. They just started showing up. | |

On my laptop's GT 630M a CUDA4.2 NATHAN_RPS ran 93% faster than the CUDA3.1 (122252 sec vs 236314 sec). This way it could even catch the 48h bonus. :) That's really amazing! Could it be that the lesser cards gain more than the high end ones? | |
ID: 25940 | Rating: 0 | rate: / Reply Quote | |
My 570s appear to gain more than my 580s so CUDA 4.2 might help the lesser cards the most. | |

OpenCL? This is all CUDA. Several versions being assigned in both Long and short. Cuda (non openCL) is 3.1 and lower. It will show in boinc manager. OpenCL 4.2 work unit is not the same. CUDA all true. Programming different, I would suppose. :) | |

Back off me hols :) Returned both my cards to stock speeds and ran 2 short WU's as a test and both completed. Now running long WU's and both seem quite happy. When we were in Thailand I was nearly tempted to buy a GTX560 to add to my collection - they were quite a bit cheaper out there than in the UK. | |

OpenCL 4.2 work unit is not the same. 4.2 is the CUDA version. This has nothing to do with OpenCL. MrS ____________ Scanning for our furry friends since Jan 2002 | |
