Open Source Radeon Gallium3D OpenCL Stack Adds Bitcoin Mining 140

hypnosec writes "The open-source Radeon Gallium3D OpenCL stack has been modified to support Bitcoin mining through the use of mining application 'bfgminer.' To mine Bitcoins using the open source GPU driver, one must use Tom Stellard's non-stock branches of Mesa, LLVM and libclc OpenCL library. Further, bfgminer must be patched as well. Once the patches are applied and modified code of the stack is used, users will be able to mine Bitcoins using the Radeon HD 5000 and Radeon HD 6000 graphics cards; however the cards have to be pre-HD6900 Cayman in case of the HD 6000 series."

    That's where the power consumption trade-off is best.

    Well, at least this useless craze is adding more economic drivers for power-efficient compute
    power, but I think we already had plenty of those drivers.

    Otherwise it's kind of dispiriting to see the continued drain of computing and intellectual resources
    by the financial sector, be it bitcoin using CPU cycles better used for medicine/science
    or very smart people and advanced equipment chasing dollars in HF trading shops.


    When you spend more time keeping core than you do playing, the game is broken.
