Support for (integrated) Intel GPUs (Ivy Bridge and later)
We have launched an application version for the BRP4 search (Arecibo data) that supports the GPUs that are build into Intel "Ivy Bridge" and later CPUs, namely
The following restrictions apply:
* Only Windows is supported (unlikely to change in the near future because of lack of Intel OpenCL drivers for the GPUs on other platforms)
* OpenCL 1.2 capable driver, e.g 184.108.40.20665 seems to work. (we got tons of errors with older drivers, but this might be fixable).
* A recent BOINC version is required (>= 7.0.42)
BRP4 tasks should finish in ca 30 minutes or less.
If for some reason you do not want E@H to send these tasks to your hosts, you can de-select Intel GPU work in your E@H project settings at http://einstein.phys.uwm.edu/prefs.php?subset=project
Intel Drivers can be found here http://software.intel.com/en-us/vcsource/tools/opencl-sdk-2013, follow the download links.
Feel free to post feedback/questions to this thread: http://einsteinathome.org/node/197052
P.S.: We restricted the app to OpenCL 1.2 capable hosts only recently, you might see error results for hosts with OpenCL 1.1 driver from previously distributed work. New work should only go to OpenCL 1.2 capable hosts.
