We haven't quite finished the enumeration process yet. BOINC won't be tied to any ICD, it'll just link against the OpenCL.dll file, as defined by Khronos, which will use the ICD(s). The latest drivers for both ATI and Nvidia appear to be useable and using the right calling conventions on Windows.
Right now we filter out everything but the GPU(s). I'm waiting on my second ATI GPU to finish up the preliminary enumeration process. ----- Rom -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Oliver Bock Sent: Monday, April 11, 2011 8:02 AM To: [email protected] Subject: [boinc_dev] OpenCL device selection Hi, I have a few quick questions regarding OpenCL device management in the BOINC core (cc) client: - How does the cc select the OpenCL devices to be used for computation? * Which device types are supported? * Can one de/select certain device types explicitly? - How is the device to be used by a given task communicated to that task? Device IDs are not simple integer enumerators like in CUDA. If a list index is supposed to do the trick one needs to make sure the cc and the science app use the same device type filter to agree on the device list content... - Which OpenCL ICD is the official cc build linked against? NV or ATI?
