I tell you here when downloading my 2 units GPU is finally completed ... Alliance Francophone |

I've noticed that some WUs are getting low credits, is there a problem somewhere? It's not happening only with the latest app, it also happened with previous versions, not sure when I first noticed it. Do you mean the ones with 0.13 & 0.08 credit? Which are 100% blanked.

It's not happening only with the latest app, it also happened with previous versions, not sure when I first noticed it. No there's some that only gives around 150-250 and not around 600-800 as normal. Right now there's only one with 140.64 Cr on my finished WUs list, last when I wrote there was 3-4 WUs with the low credit. |

I had an abortion because the download is very long ... Well, DownLoads are very slow at SETI, comaired to projects with fewer users and hosts, GPUgrid hits 20MBit, Einstein is also faster. Milkyway, WCG, etc.. Problem is SETI is constant overloaded/saturated and in too much cases the cause of a DownLoad Errors as in your case. How long for a MB (~360KBytes) and AstroPulse (8MBytes) workunit? |

Here's one with only 175.27 Cr http://setiathome.berkeley.edu/result.php?resultid=2525075894 Another one, same blanking, almost same run time, but 697.07 Cr http://setiathome.berkeley.edu/result.php?resultid=2525071993 |

Just some more feedback for Raistmer and any other AP OpenCL developers: Getting a lot of invalid results on my old HD 4670, mostly due to 30 single pulses, 30 repeating pulses, or both. This seems to happen regardless of what combination of parameters I try. The confusing thing is that, sporadically, I still get the occasional valid result. I think I'll have to revert to r555 even though it has much lower performance (especially with regards to CPU usage), it's still bound to be much better than CPU-only processing on the ancient machine it's on. There were still invalid results, but they were limited to 30 repeating pulses and there were far more valid results than invalid ones. I put all this down to the 'beta-level' OpenCL support on the HD 4000 series - I ceased all GPU processing on my HD 4850 a long time ago because of similar issues presumably arising from this. Other GPUs (HD 5000 series and later, as well as GeForce cards) continue to work very well on r1316. I'm aware there is a r1363 release, but I don't understand the parameters enough to try it. Doesn't seem as though there's as large a performance increase either. Soli Deo Gloria |

Have you tried lower unroll ? I´d suggest -unroll 4 -ffa_block 2048 -ffa_block_fetch 1024 Mike With each crime and every kindness we birth our future. |

Yes. As I mentioned, the both valid and invalid results occur for all manner of parameters. I've tried unroll of 4, 8, 10 with r1316. With r555, unroll of 4 always resulted in invalid results, whereas 10 was the only one that consistently returned valid results. Soli Deo Gloria |

I would be delighted to just download some AstroPulse files that would run! Every one shows completion in the Transfers tab, but the Tasks list always says 'Download failed'. Running all other WU's in Seti and Einstein with no problems. Windows 7 Pro 64-bit; i7-2600 quad core with 8 Gb RAM. |

Your problem is with the file ap_graphics_6.01_windows_intelx86.exe http://setiathome.berkeley.edu/result.php?resultid=2544369687 Very probably your antivirus is interfering: http://setiathome.berkeley.edu/forum_thread.php?id=68629&postid=1257824#1257824 Get the file manually: http://boinc2.ssl.berkeley.edu/sah/download_fanout/ap_graphics_6.01_windows_intelx86.exe (Probably your antivirus will say something nasty and wrong. If it does: complain to the antivirus company) If you can get the file from the above link (I can, I get the file just now and the file is the same as the one I have): put it in the ....\BOINC\projects\setiathome.berkeley.edu\ and then start BOINC In your case of Windows 7 the exact path is most likely: C:\ProgramData\BOINC\projects\setiathome.berkeley.edu\ Â - ALF - "Find out what you don't do well ..... then don't do it!" :) Â |

Just some more feedback for Raistmer and any other AP OpenCL developers: Actually I'm trying to maintain compatibility with HD4xxx though has no hardware installed now. But HD46xx low-end ones AFAIK and have some different issues. Special LHD4 build for them still in debugging. From the other side I would not expect same failures on HD4850. Can you replace HD46xx with HD48xx on that host ? |

Thanks BilBg. Trend did try to block it, and I placed it on the 'approved' list. I replaced the one in the folder which was only 9kB. Time will tell, once I get another AP download. |

Special LHD4 build for them still in debugging. From the other side I would not expect same failures on HD4850. Can you replace HD46xx with HD48xx on that host ? Sorry, no, the HD 4850 I put in the machine for my brother and besides, HD 4850 is PCIe, HD 4670 is AGP. For HD 4850's issues, I think it's driver issues more than anything else. After getting yet another 30 single pulses result on the HD 4670, I reverted to r555 and re-processed the task. Hasn't validated yet, but it seems to be giving more reasonable results again. As mentioned previously, the puzzling thing is that there are still some valid results produced with r1316. These two were validated recently, so they're still present in the database at time of writing: 2543227294 Oops, no, scratch that. Second one just got purged as I was writing... Edit: If you want a tester for your special HD 4000 build, I'm willing to help. Will just take a while as 0% blanking AP WUs take about 7.5 hours with r1316, just under 10 hours with r555. Soli Deo Gloria |

Currently I'm busy with MultiBeam, but will keep your proposal for future, thanks. |

I'm in no hurry, I only offered because you mentioned developing a special build. Best wishes for MB development. Soli Deo Gloria |

Only as Info, Application runs without errors on a low low lowest end HD4350 ^^ ~24h for 1 WU |
