NVIDIA GPU's of the 4xx, 5xx, 6xx series normally run better when more than one instance runs / device. But this is difficult to do manually. This tool does this automatically and you get a result within 15 minutes. http://www.efmer.eu/forum_tt/index.php?topic=974.0 Warning, this tool is tested on a limited number of machines. (V 1.0) It uses the Lunatics optimized exe as a reference. But you can drop in any version you like as long as you update the config.xml file. My results: GTX 295: 260 sec / device = 130 sec / board GTX 480: 98 sec / device = 98 sec / board GTX 590: 104 sec / device = 52 sec / board Interesting to see what a 690 does.

Nice tool! Worked fine on my system. :-) Thanks! |

Nice little app! Automatic test's result was: count 0.5 fastest. GTX 690, Devices 2, Count 0.50 x41g Results: Device: 0, device count: 2, average time / count: 232, average time on device: 116 Seconds (1 Minutes, 56 Seconds) Device: 1, device count: 2, average time / count: 234, average time on device: 117 Seconds (1 Minutes, 57 Seconds) x41z Results: Device: 0, device count: 2, average time / count: 174, average time on device: 87 Seconds (1 Minutes, 27 Seconds) Device: 1, device count: 2, average time / count: 178, average time on device: 89 Seconds (1 Minutes, 29 Seconds) -Kimmo- Computers: obelix |

Great app!! EVGA GTX 560: count: 1, average time / count: 217, average time on device: 217 Seconds (3 Minutes, 37 Seconds) count: 2, average time / count: 311, average time on device: 155 Seconds (2 Minutes, 35 Seconds) count: 3, average time / count: 450, average time on device: 150 Seconds (2 Minutes, 30 Seconds) Running one at a time the GPU load was in the low 60s, two at a time was low 90s, three at a time was high 90s. Four at a time was low 50s with screen lag. Is this normal (the low 51-54 GPU%)? I ended up cancelling the four at a time test because it was still running after 35 minutes. </Tazz> |

EVGA GTX 560: The program stops at 4 programs / device. But cuda tasks may run into problems and get stuck. Probably a memory problem in the card. But in your case the CPU may not be able to keep up. The cancel button, kills the running cuda tasks and clears up the disk. 4 is too much for some cards and the overhead of the CPU increases, but that depends on the CPU. As you can see the gain from 2 -> 3 is already low. TThrottle Control your temperatures. BoincTasks The best way to view BOINC. Anza Borrego Desert hiking. |

Nice little app! Automatic test's result was: count 0.5 fastest. With the 41g the 690 is actually a bit slower than the 590. The 41z is quite a bit better. TThrottle Control your temperatures. BoincTasks The best way to view BOINC. Anza Borrego Desert hiking. |

Hi Fred, Cool tool :) can you make it cope with either command line parameters for the exe, or not die if a mbcuda.cfg (x41z) configuration file is present ? (it dies when trying to copy into the slot for some reason, but it does put the file there). It would be handy for finding good settings, for which x41z has a few that the best setting could depend on the count. Jason "Living by the wisdom of computer science doesn't sound so bad after all.

Results with gtx670, driver 304.79, XP 32 bit: Device: 0, device count: 1, average time / count: 139, average time on device: 139 Seconds (2 Minutes, 19 Seconds) Device: 0, device count: 2, average time / count: 261, average time on device: 130 Seconds (2 Minutes, 10 Seconds) Device: 0, device count: 3, average time / count: 389, average time on device: 129 Seconds (2 Minutes, 9 Seconds) The best average time found: 130 Seconds (2 Minutes, 10 Seconds), with count: 0.50 (2) 1) Why is 130 seconds better than 129? :=) 2) Using the automatic option and a count of .25, it did not test for 4 at a time. I ran that test separately and got: Device: 0, device count: 4, average time / count: 485, average time on device: 121 Seconds (2 Minutes, 1 Seconds) So I guess I'll stay with 4 at a time.

GTX 680, win7x64sp1, driver 304.79, lunatics_x41z_win32_cuda50preview.exe, at default settings (no mbcuda.cfg or command line switches) : Device: 0, device count: 1, average time / count: 88, average time on device: 88 Seconds (1 Minutes, 28 Seconds) Device: 0, device count: 2, average time / count: 155, average time on device: 77 Seconds (1 Minutes, 17 Seconds) Device: 0, device count: 3, average time / count: 229, average time on device: 76 Seconds (1 Minutes, 16 Seconds) Device: 0, device count: 4, average time / count: 302, average time on device: 75 Seconds (1 Minutes, 15 Seconds) Any chance of adding 5 & 6 ?

Hi Fred, Easy, the parameter is now --device x to set the right device. I can make a field where you can put additional. Like -- devices x additional PS can you give me the x41z for testing? TThrottle Control your temperatures. BoincTasks The best way to view BOINC. Anza Borrego Desert hiking. |

You can do that manually. (manual button) On auto mode the program tens to hang after 4 for sure. Probably out of memory, but doesn't exit. I could add a max in the config.xml. TThrottle Control your temperatures. BoincTasks The best way to view BOINC. Anza Borrego Desert hiking. |

1) Because the extra instance causes more overhead, I subtract 1 second. Not worth the extra CPU. 2) The auto option doesn't use count, only the devices. The value is used when you press the button below it. TThrottle Control your temperatures. BoincTasks The best way to view BOINC. Anza Borrego Desert hiking. |

Hi Fred, Sure I can authorise you for testing x41z ;) , please PM address (sure I had it, but not sure where) "Living by the wisdom of computer science doesn't sound so bad after all.

Or more than 1 app or multiple versions of the dll files. I could add a dropdown box to select different tests to copy. Adding e.g. 3 entries into the config.xml Like x40g x41 x42 And maps data, data1, data2 ..... TThrottle Control your temperatures. BoincTasks The best way to view BOINC. Anza Borrego Desert hiking. |

Hi I´m a x41z user, your build works ok in some hosts but when i try to use in this host: 6690764 (with just one 590 EVGA) its give me 100 sec in all measures (1, 2 or 3 WU), and shows just 1 device (the 2 GPUs on the 590 works OK with Boinc processing 2x2WU at a time XP32 and no OC). Do you know anythink that could cause this? |

Well, I can't get it to work. I have one NVIDIA GT 520 installed. When I run the program with the default "Devices 1", "Count 0.50", I get this: Starting test: (lunatics_x41g_win32_cuda32_perf.exe) 25 August 2012 - 20:56:50 Start, devices: 1, device count: 2 25 August 2012 - 20:57:07 Program failed to start on slot: 0 25 August 2012 - 20:57:07 Program failed to start on slot: 0 25 August 2012 - 20:57:08 Program failed to start on slot: 0 25 August 2012 - 20:57:08 Program failed to start on slot: 0 So ... what am I not doing correctly? (Yes, I stopped BOINC Manager before executing the performance utility). |
