I'm not sure if release BOINC versions report that second line with OpenCL details or not. If not, the older way to check if OpenCL was correctly installed was to look for the tick in the OpenCL box in GPU_Z. I was just showing the details from my Event Log to explain that the CAL line alone does not relate to the OpenCL version installed.
----------------------------------------A more complete list of OpenCL capabilities and extensions similar to that found in stderr_txt section of result log of a completed task can be found in client_state.xml. [Edit 1 times, last edit by kashie at Mar 14, 2012 3:56:56 PM] |

Since I have already shot myself in BOTH feet today, what the heck. I just put 196.10 on Dataman05. As the man who jumped off a 50-story building was heard to say halfway down, "So far so good."  Any update on how the driver driver worked DM? The one prior to 196.10 had problems enough I had to revert back to an earlier version.

The guy that jumped got lucky... he stopped early on the pedestrian way curb.
----------------------------------------These numbers keep coinciding... is that 296.1 of NVidia http://www.nvidia.com/object/win7-winvista-64bit-296.10-whql-driver.html something else? --//-- [Edit 1 times, last edit by Former Member at Mar 14, 2012 3:57:38 PM] |

Juat trying to carry on with the clarifications,
NVidia cards have to be at least compute capable 1.2, have a reasonably up to date driver, and be over a minimum GFlops peak. What is this GFlops peak value at present, and might it change? Is anyone comprising a list of viable cards + drivers? Can someone clarify if the project requires OpenCL 1.1 or 1.2? Both 1.2 and 1.1 have been stated as requirements, and in the past 1.0 was stated. Some people are wrongly listing cards as not capable. As Kashie said, some people think their AMD cards are not up to the CC1.2 requirement - So again, CC1.2 is an NVidia Only requirement, nothing to do with AMD/ATI. Most people with AMD cards that are not working probably don't have the correct Catalyst suite; partial and old drivers are not enough. |

There was a post yesterday that "OpenCl extension cl_khr_local_int32_base_atomics" is what's required as capability. One other post connected this to compute capability of 1.2 of NVidia.

Since I have already shot myself in BOTH feet today, what the heck. I just put 196.10 on Dataman05. As the man who jumped off a 50-story building was heard to say halfway down, "So far so good." Any update on how the driver driver worked DM? The one prior to 196.10 had problems enough I had to revert back to an earlier version. You must be clairvoyant Nano, as I just rolled it back but NOT for crunching reasons. Dataman05 has a GTX285 in it that was not a very popular card and I have had some problems with it. I install new drivers on it first because if it works on that card, it always works on the other 13. The problem was if I run a youtube video the screen shuts down for ~ 2 seconds then refreshes and runs the video. When you exit the video it does the same thing. I don’t have time to investigate why so I rolled it back to 285.62 and I plan to stay there until I have some compelling reason to upgrade. (As a side note, we just got home from a 7-month vacation and my “better half” has a task list for me the size of “War and Peace”. I know it is hard for a cruncher to believe but not one of those tasks includes cleaning my servers, installing new drivers, or running GPU BETA wu’s.   ) |

Well I had 3 valid tasks and according to BOINC my HD 5870 has OpenCL 1.1 drivers installed. OpenCL 1.2, when was that released? I have 12.1a Preview drivers which are not very old.
----------------------------------------As I said previously I don't think any RV7xx cards qualify, so that's HD 4870, 4850, 4770, etc. GFLOPS value reported by BOINC for ATI/AMD cards doubled from BOINC 6.13.7*, notice my HD 5870 is reporting 5920 GFLOPS peak and mikey159b's HD 5870 is reporting 2720 GFLOPS peak. It's possibly still incorrectly calculated for VLIW4 architecture if it's still using the X5 multiplier that is correct for VLIW5. If the old formula is still being used perhaps GFLOPS value for GCN class cards such as Tahiti and Cape Verde may be incorrect as well. Inconsistent GFLOPS reporting may be one of the many possible causes of problems with GPU claimed credit until host scaling is supposed to stabilise. This may have been one of the reasons that POEM required at least BOINC 7.0.xx version when they unsuccessfully tried to introduce CreditNew with a GPU application. *client/scheduler: the code for estimating peak FLOPS of ATI GPUs (from Crunch3r) has a multiplier of 2.5 for cores/processor. This is possibly because give a double-precision estimate. But actually we want single-precision. Change it to 5. [Edit 2 times, last edit by kashie at Mar 14, 2012 5:42:03 PM] |

Thanks,
That compute device extension is available in OpenCL_1_0, for Linux and Windows; SDK v2.1 (2010-05-28) - ATI Catalyst™ 10.4 (8.723) and above. So unless there are other requirements, it's as predicted months ago, anything, but the most basic of cards, from the HD5000 range up should support OpenCL, with a reasonably modern bug-free driver. These should be good HD5000 series cards: ATI Radeon HD 5800 Series GPU ATI Radeon HD 5700 Series GPU ATI Radeon HD 5600 Series GPU ATI Radeon HD 5500 Series GPU ATI Radeon HD 5400 Series GPU ATI Mobility Radeon HD 5800 Series GPU ATI Mobility Radeon HD 5700 Series GPU ATI Mobility Radeon HD 5600 Series GPU ATI Mobility Radeon HD 5400 Series GPU While HD4000's have OpenCL beta support, as Kashie pointed out Local Memory (on card) may be required, which would mean they can't work. On the 266 NVidia beta, the bug is still there, so Avoid 295 & 296 NVidia drivers. |
