Oh hell yeah, fellas! We are IN BUSINESS! I have confirmed (via initial test only), that AstroPulse pulse correction is now being CORRECTLY DETECTED on R340 driver 341.44!!! I'll continue to do testing, but thinks are working so far! Raistmer: Can you please do some testing on your end, using 341.44, to verify it's working for you? Richard: Let's go get some drinks, bud! PS: Can you please confirm some testing on your 9800GT? |

Congrats on persisting through tough times, and coming through :D It's no secret there are a lot of changes with long term support, coming from internal nVidia reasons, to global MS and Google decisions/changes. Keeping the widest range of backward support open is IMO a win for users, and the companies involved. Now can you get Google to support OpenCL &/or Cuda on suitably equipped [stock] nexus devices ?

Richard: Yay! Yes to both. Timezone clash means I've only just seen this - I'll load up as soon as the coffee kicks in. |

Raistmer: Build with lifted ban for 341.xx drivers: https://www.dropbox.com/s/uedoe9qoxnqy6qu/AP7_win_x86_SSE2_OpenCL_NV_r2745.7z?dl=0 |

Raistmer: Raistmer: You cannot lift the ban for all 341.xx drivers. You still need to ban any driver between 337.88 and 341.44. For example, 341.21 will give bad results. |

Confirming that tests complete with 9800GT, using Windows 7/64 and matching 64-bit WDDM version of the 341.44 driver. All six problematic NV OpenCL test/demo apps passed. Original Astropulse index case (r2690, single_pulses WU) passed and correct pulses found: With 341.44: Single pulse: peak_power=38.55 dm=-5720 fft_num=13991936 peak_bin=13999216 scale=2 Single pulse: peak_power=653.6 dm=-5749 fft_num=25804800 peak_bin=25807872 scale=9 Single pulse: peak_power=91.79 dm=-5800 fft_num=3063808 peak_bin=3071328 scale=5 Single pulse: peak_power=63.35 dm=-5803 fft_num=3063808 peak_bin=3071344 scale=4 With 337.88: Single pulse: peak_power=38.55 dm=-5720 fft_num=13991936 peak_bin=13999216 scale=2 Single pulse: peak_power=653.6 dm=-5749 fft_num=25804800 peak_bin=25807872 scale=9 Single pulse: peak_power=91.79 dm=-5800 fft_num=3063808 peak_bin=3071328 scale=5 Single pulse: peak_power=63.35 dm=-5803 fft_num=3063808 peak_bin=3071344 scale=4 I'd call that a match. |

AWESOME! Richard: Also, OpenCL SDK tests 2 and 7 were failing for even R337 drivers, and for me, even those tests work successfully for me on R340 341.44. So, I believe this means that multiple bugs were likely fixed. |

Great news indeed. Nice to see that pre-Fermi GPUs can still be used constructively. Soli Deo Gloria |

My bug ticket has been updated (pasted below). Richard: Would it be possible for you to verify that my findings in the 3rd message, also apply to your 9800GT? Thanks. ----------------------------------------- 19 February 2015 8:28 pm JacobKlein The last driver for my FX 3800M, was 12/5/2014, and did not include the fix. When can we expect a fixed driver to be released? Thanks, Jacob Klein ----------------------------------------- 25 February 2015 10:54 pm Kevin Kang Hi Jacob The latest R340 driver version - 341.44 was posted on February 24, 2015, it should contain this fix, please let us know if it works for your FX 3800M GPU. Thanks! http://www.nvidia.com/download/driverResults.aspx/82388/en-us Thanks, Kevin ----------------------------------------- 26 February 2015 4:47 am JacobKlein Hi Kevin/Team, Yes, 341.44 does solve the problems I was having with SDK examples 19, 21, 26, 34, 36, 37 on R340 drivers. And it looks like it also solves the issue with SDK examples 2, 7, which affected R337 and R340. And it also appears to solve the issue in Bug 1554016, though that bug reporter will need to do final verification. Questions: 1) SDK example 9 still fails with a TDR and output "Out of Memory? - Error # -5 (CL_OUT_OF_RESOURCES) at line 248 , in file .\oclMatVecMul.cpp" --- Is that expected? And can you reproduce that error? 2) SDK example 13 crashes on exit - is that expected? 3) On several examples, my FX3800M output value for "CL_DEVICE_LOCAL_MEM_SIZE" reports "15 KByte", yet in R337 it reported "16 KByte"; which value is correct? Thank you, Jacob Klein |

Richard: Would it be possible for you to verify that my findings in the 3rd message, also apply to your 9800GT? Thanks. Sure. Could you identify the remaining failure samples by name, please? The download page I got mine from was un-numbered, so #9 and #13 are ambiguous. |

So... Did your SDK example 9 fail with a TDR at all, with output "Out of Memory? - Error # -5 (CL_OUT_OF_RESOURCES) at line 248 , in file .\oclMatVecMul.cpp"? It looks like you had no problem, right? Did your SDK example 13 crash on exit? Output will not indicate the crash. Actually, it looks like yours did not detect a DirectX 10 device, and exited before it could crash. Mine attempted and crashed and burned. I see your SDK example 22 shows "15 KByte" for "CL_DEVICE_LOCAL_MEM_SIZE", on 341.44. But did it show "16 KByte" on 337.88? |
Richard Haselgrove Send message Joined: 4 Jul 99 Posts: 14650 Credit: 200,643,578 RAC: 874 |
ex 9: clean result, no errors ex 13: no crash. Agree non-capable device ex 22: didn't run under old driver, no comparison readily to hand |

Any confirmation that new build works OK with 341.44 driver on pre-FERMI cards? |

Any confirmation that new build works OK with 341.44 driver on pre-FERMI cards? Would you consider this a release candidate? If so, I'll dig the ancient 9800GT out of storage yet again and run the bench. If we're not near a release, I'll leave it a bit later to test any other tinkerings as well - I have to re-rig the supplementary power supply too, so it's all a bit of a hassle. |

Any confirmation that new build works OK with 341.44 driver on pre-FERMI cards? My 9800GTX+ is 200 miles away and powered down, the earliest i try it is Saturday, Claggy |

I will gladly test with my FX3800M, if someone provides me with complete instructions on how/what to test. |

Any confirmation that new build works OK with 341.44 driver on pre-FERMI cards? There were no updates in AP tree since last beta. So yes, if this app works Ok it will be supplied to Eric for upload on beta and to you to include in installer update. |
