I think I have something of a handle on the way the Cuda23-50 map. The higher the number, the newer the GPU chip set will run more efficiently on it. At least that is what I am getting from the documentation and the sample .CFG files and yes my GTX 750Ti appears to be running "like greased lightning" on Cuda50 files. But what about the Radeon/ATI equivalents? I see at the moment: opencl_ati_cat123 opencl_ati5_? etc. Is there some kind of mapping to either the equivalent CudaXX file or something that gives you a feel for what each type of file usually works best with? For instance my Radeon GPU for Seti parameter files have both a mb_.....ati___.txt and a mb_....ati5_....txt parameter file. So clearly there is a distinction between ati and ati5. I am leaving Astropulse completely out of the question because I don't want to muddy the waters. I am still working out how my A-10 5700 oughta be running so I am interested in the Radeon side of the house. Thanks, Tom A proud member of the OFA (Old Farts Association). |

There are 2 ATI apps. OpenCL ATI OpenCL ATI HD5 As I recall HD5 was intended for Radeon HD5000 series & newer. Where the other is for HD4000 & newer. The other plan classes are primarily because ATI drivers don't have have an easy way to tell BOINC their versions information. So a new plan class has to be created when a version issue comes up. The most recent opencl_ati5_nocal is because newer cards/drivers don't provide a CAL version to BOINC. CAL was ATI's version for GPGPU computing, but when AMD bought ATI they dropped support for CAL in favor of OpenCL.

Thank you for the explanation. Do any of the groupings have a tendency to process faster on same Radeon gpu than others? Or is this one of those throw enough mud at the wall for your system and see which sticks issue? Thanks, Tom A proud member of the OFA (Old Farts Association). |

Thank you for the explanation. In principle you can say HD 5 version is faster on x770 and above cards. Same for 270/280 and 290. With each crime and every kindness we birth our future. |

As a further point of clarification, the project plan classes with ati5 in the name are the non-HD5 app versions. IOW (opencl_ati_cat132) is HD5 but (opencl_ati5_cat132) is not. Joe |

IOW (opencl_ati_cat132) is HD5 but (opencl_ati5_cat132) is not.Joe I think I quite agree. There wasn't a logical progression on the naming convention(s)? Someone want to post a more or less exhaustive list and divvy them up into the assorted classes they belong to for me? Thanks, Tom A proud member of the OFA (Old Farts Association). |

I have a vague recollection of a post explaining that the '5' in ati5 referred to the version number reported or received by BOINC when determining the class of ATI/AMD GPU, where '5' referred to HD4000+. It's an unfortunate coincidence, hence the confusion. Fortunately, plan class names don't matter much on anonymous platforms. Soli Deo Gloria |
