MilkyWay@home Version 1.38 Released
(Message 65286)
Posted 26 Sep 2016 by Sebastian* Post: Looks like my HD 4850 GPUs don't get work any longer. It got work on the 24th. I now get the message when i update Boinc, that i got 0 new tasks. Has something changed between then an now? Did the Downtime cause the issue? http://milkyway.cs.rpi.edu/milkyway/results.php?hostid=307550 The computers with the HD 7970 get work tho. And i get a lof of that in the Event Log from Boinc: 26/09/2016 21:18:26 | Milkyway@Home | Message from task: 0 Seem it shows up once a WU is finished. Something was changed because of the Downtime. Any ideas? |

Posted 20 Sep 2016 by Sebastian* Post: The Computer with the R9 390X isn't even initializing the Project. It does not download the .exe -file or any other files. I copied them in manually, with an app_config file. I got the message, that the app_config file contains no known executables. There must be something wrong at the initial detection, when Boinc sends, or the server requests infos about the hardware. Any idea how i can monitor that traffic, to give you some hints? |

Posted 20 Sep 2016 by Sebastian* Post: Hello Jake, i tried the new version on my R9 390X with the latest driver. It is requesting Tasks, but getting none. Removed an added the Project again with no success. No error Message so far. Could the error be, that the newer cards support OpenCL 2.0 instead of 1.2? And the software is only checking for 1.2 and is ignoring newer versions? There is no driver version reported, when i check my computers in Boinc for this computer. All other from HD 4xxx cards to R9 280X cards report a driver version. Computer ID: 704045 If you can check on the server side, why i don't get any workunits. Edit: I added a more detailed request at the end of this message. 9/20/2016 11:51:58 PM | | Starting BOINC client version 7.6.22 for windows_x86_64 9/21/2016 12:22:39 AM | Milkyway@Home | [work_fetch] set_request() for AMD/ATI GPU: ninst 1 nused_total 0.00 nidle_now 1.00 fetch share 1.00 req_inst 1.00 req_secs 1728000.00 |

Posted 20 Sep 2016 by Sebastian* Post: Peter, from what i can see, your 9500GS (which is a 9500GT) should be able to run Einstein. It has compute capability 1.1 which should do it. For Milkyway you need 2.0 i think, which the 2xx Series had. |

Posted 20 Sep 2016 by Sebastian* Post: Hey BQL_FFM, what do you mean by "i buy it!" And could you unhide your PC here in milkyway? I would be intrested in how fast the GTX 1060 runs through the Milkyway@home workunits. Peter Hucker, you can leave your Intel integrated GPUs on Einstein. The Intel GPUS don't have double precision, so they can't run Milkyway. I am a little bit confused by you Nvidia GPU, i can only find a 9500M GS or a 9600GS. If it is a 9600GS it should be able to run at least Einstein@home. |

Posted 19 Sep 2016 by Sebastian* Post: Peter Hucker, yes, that is the message i mean. But your Nvidia card has no double precision capability, so it can't run Milkyway@home. Colonywest, i guess it is the Nvidia driver, since it gave me the most trouble on linux. But i don't have much experience there. Maybe some permissions are missing to fully utilize the Nvidia driver. If you find a solution, please tell me. I never got the latest version of Boinc working properly on a Linux system. And the Nvidia driver always made things worse for me. |

Posted 19 Sep 2016 by Sebastian* Post: Jake Weiss is working on the GPU detection issues. Currently no newer cards than the R9 280X or 7970 are detected by Milkyway@home. Nvidia cards seem to work well, as older AMD/ATI cards do. |

Posted 17 Sep 2016 by Sebastian* Post: Milkyway has a problem with GPU detection for newer cards than the R9 280X (HD 7970) You should get the same message i did, because Milkyway thinks you have another GPU. The good news is, that Jake is working on a solution to that problem. |

Posted 16 Sep 2016 by Sebastian* Post: Thank you for the information Jake. I don't know how far you are with your bughunting on the gpu detection stuff. I just tried to connect a R9 390X to Milkyway and got: 9/16/2016 11:54:20 PM | Milkyway@Home | Message from server: ATI GPU R600 (R38xx) does not support OpenCL However the GPU was detected correctly by Boinc, exept for the shown Gigaflops. They were around 3000 instead of nearly 6000. But i don't give too much about it, since the R9 280X GPUs are detected with the double Gigaflops they really have. zioriga, you said now your GTX 1080 is working correctly, but i haven't seen any valid workunits on your account. You have some units running, but not uploaded yet. Would like to see, if it runs correctly. |

Posted 14 Sep 2016 by Sebastian* Post: Hi Joseph. I have to agree to Keith Myers, but there is a problem with your HD 4xxx series cards and Windows 10. There are, and will never be, drivers from AMD for your HD 4xxx series cards for Windows 10. Check yourself on the AMD driver page. I brought online a computer with 3 HD 4850s. I run Windows 7 with the latest driver for the HD 4xxx series cards. (Catalyst 13.9) It seems to run quiet well from what i can see. Windows 8.1 is the lastest OS AMD supports drivers for. If you considering changing your OS. Or you could search for just the OpenCL SDK from AMD. But i am not sure if it still exists (it is integrated into the driver now), or if it will give the Microsoft drivers OpenCL support. I would give it a try before you remove your OS. |

Posted 10 Sep 2016 by Sebastian* Post: Thanks for the info Jake :) apohawk i can confirm the HD 6950 running well with the latest driver for it and with the current Milkyway workunits. |

Posted 6 Sep 2016 by Sebastian* Post: Hello mancausoft, i think you are running OpenCL on your Nvidia GPU (GTX 750M Device 0) but all seem to error out. I have no experience with Darwin as an operating system, but i think it could be a driver issue, or some permissions are missing so Boinc is not allowed to use all the files it needs. Your device 1 (second device) is you Intel GPU integrated in you CPU. But this one does not have a double precision compute capability. Look for: "Device doesn't support double precision" in your last post. |

Posted 3 Sep 2016 by Sebastian* Post: Hello Tim, Yes, you are right the Numbers are wrong. The numbers of my AMD cards are there where they should be. I will test MW on my Titan blacks tomorrow. Did you enable inside the driver the double precision option? If this is disabled, then the double precison number could be true. And even when you get the Titan Blacks fully utilized, then it is slower than a AMD card with one Terraflop. Nvidia does not really care about OpenCL, they still pushing CUDA. So OpenCL is not optimized very well. |

Posted 2 Sep 2016 by Sebastian* Post: Hey everyone, i set up a HD 5970 (Dual 5870 on one card). I installed the newest not beta driver on it, and it runs smoothly. If you have such cards (HD 5850 or 5870) then you can use them without troubel for MW. I will test a 69xx card soon, but i expect the same results :) @Keith Myers Yep, i agree to your last post. Most projects only have a few persons, even students working on it (programming, maintaining server) so that only for one GPU brand is optimized. You have to pick your cards depending on what projects you like most. A GTX Titan black has 1700 Gigaflop of double precision power, but it can barely compare to a 7970 with 1000 Gigaflop here in Milkyway. Primegrid is the other way around. I can image that even OpenCL is hard work for the project programmers. Even if they only optimize on one manufacturer, they have to deal with different GPU architectures. And there is no help from the companies as well, since you can't earn profit on that :( |

Posted 1 Sep 2016 by Sebastian* Post: Thanks for all the feedback so far :) @Keith Myers The problem with Nvidia Cards is, that they have almost no Double Precision crunching power except for The GTX Titan or Titan Black (both Kepler). I also had some driver issues with my Titan Blacks, when the cuda version was updated and a bug was in that version. And i am glad that Nvidia at least supports OpenCL 1.2, so we can run them here :) @_heinz Your Titans can do quite well on Milkyway. If you want to run it a little, you have to set in the driver that double precision is used. And you have to use the app_config file to run 6 to 8 workunits in parallel per card to get them fully loaded. |

Posted 31 Aug 2016 by Sebastian* Post: Hello Jake, thanks for hunting the bugs. For the GPU dection issu, is suggest you contact Einstein@home, they never had issues with the GPU detection in my opinion. And AMD GPUS work very well there with OpenCL. I can test the older AMD GPUs there with the latest available driver for them (5870 or 6870 / 6970 GPUS) I can also bring them online for Milkyway@home. For some reason, with driver newer then Catalyst 13.1, Milkyway@home aborts some tasks. (Have to check which one) Thanks to Joseph, for reminding us about maintenance. But i have to object to the 5 years of GPU life-time. The GPU-Chips might hold that long, but the fans usually fail much erlier. And they are very hard to find Can anyone check, how well the Nvidia detection works? I can check with my GTX 980. When anyone has a 700 series card, or even a 1000 series card, it would be nice to see some feedback :) |

Posted 14 Jul 2016 by Sebastian* Post: Thanks Jake. It looks better now, some of the "fixedangles" still error out. At a closer look, the fixedangles_simBPLfixed2_3 (2_2 and 2_1) run through, the 1_1 and 1_2 error out. I guess we have to run the 1_x versions through until they are gone? Edit: Some of the 2_1 error out as well. |
