1) Message boards : Number crunching : sometimes my computer uses 2 or 1 gpu's (Message 62534) Posted 10 Oct 2014 by TJ Post: I have no issues with 2 nVidia GPU's in one rig and also one nVidia and one AMD in the same rig works perfect together.
2) Message boards : Number crunching : sometimes my computer uses 2 or 1 gpu's (Message 62530) Posted 9 Oct 2014 by TJ Post: I just read the prior thread about the amd's are for gaming and ignore parts of the programming that crunchers use. I am in the beginning of putting together a new rig. It sounds like it's time to switch to Nividia. Any comment? nVidia cards are more versatile as projects who supports GPU, work on nVidia but not always on AMD. However it depends on the project you will do. Here at MilkyWay double precision is necessary and then AMD is a lot faster then nVidia. Updting drivers with nVidia is far more easy then with AMD, but others will say the opposite. In my experience AMD does not clear all of the old stuff and to remove everything manually takes a lot lof time and effort.

5) Message boards : Number crunching : Some "strange" crunchers (Message 62475) Posted 5 Oct 2014 by TJ Post: I see several Completed, can't validate messages at my results and while checking there I see at least two wing(wo)men with about 4000 results all Aborted by user. This is not helping the project. Can it be investigated? PS: if moderators have a better name for this thread, please change it. Please link some examples.

7) Message boards : Number crunching : All WU de_80_DR8_xxx error out after 6 seconds (Message 61818) Posted 1 Jun 2014 by TJ Post: The title says it all, that is what happening on my rig with AMD 5870.
8) Message boards : News : N-Body 1.38 (Message 60536) Posted 7 Dec 2013 by TJ Post: These N-Body 1.38 simulation WU's use 8 cores of my i7 with HT on. If I set to use only 90% of the cores to use, si that I can use one for GPU feeding, they don't run anymore, waiting to run. Why is that? In the past these N-Body's run with all the available cores. Thanks.
9) Message boards : Number crunching : Computation errors. (Message 60142) Posted 11 Oct 2013 by TJ Post: All my WU's failed after updating to driver 13.1. Now I updated to the latest driver, 13.9 on a HD5870 and BOINC 7.0.64 Now MilkyWay@Home v1.02 (opencl_amd_ati) all have computation error in seconds, but the Milkyway@Home Separation (Modified Fit) v1.28 (opencl_amd_ati) run fine. Other projects do good as well. Is this still the driver update since begin this year, adn is only 12.1 good for MilkyWay@home?
10) Message boards : Number crunching : Computational Error? (Message 58462) Posted 31 May 2013 by TJ Post: AMD is again changing their software to favor gamers and not crunchers, they are working on it but don't hold your breath! If you ever find a version that is stable and just works AND you are not a gamer, then don't upgrade unless you hear the new one is MUCH faster and has been tested by others with your configuration. I am still running version 11.9 on one of my pc's and it works here just fine. I agree completely!! Updating GPU software/drivers is almost always in-favour of the gamer. 13.4 is currently on my "thou shall not pass" software list. I agree too, but there was an issue with my 12.x version and Einstein@home. You have 13.4 drivers and MilkyWay is working with no errors, do I understand that from your post correctly? Then I must update at once. Thanks.
11) Message boards : Number crunching : Computational Error? (Message 58436) Posted 29 May 2013 by TJ Post: I have Catalyst 13.3 for a while on my rig and all MilkyWay's will error out. Going lower got problems with installing, de-istalling and a lot of pain. Eventually the one proper installed had an app missing according to BOINC and wouldn't crunch Einstein and Albert at home. They run smooth now, but MW don't. So I have to wait for a new good driver or an update of the MW-app.
12) Message boards : Number crunching : After driver update all gpu wu's fail (Message 57602) Posted 21 Mar 2013 by TJ Post: I did try to re-install 13.1 again for several times, as an update, as clean install with first removing, booting and such, but then the message that opencl app was missing. I give in, Windows and AMD win this time. Next time Linux and nVidia.
13) Message boards : Number crunching : After driver update all gpu wu's fail (Message 57586) Posted 21 Mar 2013 by TJ Post: Okay this morning again several hours updating AMD stuff. Version 10 and 12 installed no joy, even extra errors on my systems with graphics and display. Installing and re-installing is bad for windows as well. I have eventually installed AMD 13.3 beta and now my displays are stable, no flickering and Einstein@home is running the OpenCL. Milyway not they error out immediately. Well Einstein@home is my main project, thus until fixed no more Milkyway for the AMD rig. What OS are you using? If you are using XP you CAN NOT go beyond version 12.1 as OpenCL support for XP was dropped after that. See this page http://www.hal6000.com/seti/boinc_ati_gpu_cheat_sheet.htm which has the download links at the bottom of it. Win7 x64 ultimate

15) Message boards : Number crunching : After driver update all gpu wu's fail (Message 57559) Posted 19 Mar 2013 by TJ Post: My guess is you are using 7.0.28, which has a bug in OpenCL detection. You are right but I have crunched 1000's of WU for both Einstein and Milkyway with this version.
16) Message boards : Number crunching : After driver update all gpu wu's fail (Message 57552) Posted 19 Mar 2013 by TJ Post: Okay I am now more then 4 hours installing and de-installing amd drivers. The 13.1 driver does not work any more an any project.

17) Message boards : Number crunching : After driver update all gpu wu's fail (Message 57491) Posted 13 Mar 2013 by TJ Post: Indeed Einstein@home is working for me fine too, but Milkyway not. Previous drivers gave issues with flickering screens, sometimes a window with browser maximized got complete white, or one WU stuck. Seems running for hours and needed hours more. Had to suspend it, wait and then start again. Within 2 minutes WU is ready then. So that is why I update to beta driver. Will see is a 12.x driver will work. On the other hand my system is now running smooth and no more flickering windows, especially in the BOINC tray. Einstein@home (my main project) runs fine as well. So I keep the beta drivers for a while, and thus no Milkyway at the moment.

19) Message boards : Number crunching : Computation errors (Message 57473) Posted 10 Mar 2013 by TJ Post: I will try the update, thanks. One more thing to mention: I have updated the AMD drivers to latest beta ones, as I got spontaneous reboots of the system when doing gpu (Einstein or Milkyway). Screens blink as well at times. Seems to be stable now with Einstein and Rosetta for 24 hours. Win7 64bit and AMD HD5870 (1GB).
