With OpenCL support of Intel GPUs on Mavericks, will there be an OpenCL version of Collatz available for Macs w. Intel GPUs? I can help with testing as I see my Intel GPU also available in the newest standard version of BOINC on Mavericks

Want to know a secret? The executable is the same for nVidia, AMD, or Intel GPUs. The only reason the file names are different is because BOINC can't handle having one executable sent to multiple platforms, at least not without creating a totally custom plan class.

If you want to test it, grab the v4.20 nVidia app from here:
http://boinc.thesonntags.com/collatz/forum_thread.php?id=1077&postid=17769#17769

1. change the plan class in the app info from "opencl_nvidia" to "opencl_intel_ gpu"
2. change the coproc type in the app info from "CUDA" to "INTEL GPU"
3. rename the executable and config files to solo_collatz_4.20_x86_64-apple-darwin__opencl_intel_gpu and solo_collatz_4.20_x86_64-apple-darwin__opencl_intel_gpu.config respectively
4. change the file_info and file_ref file names in the app info to match #3

Thanks I got it to register, using intel_gpu instead of "INTEL GPU" However, no new tasks available on solo_collatz so couldn't test it fully. Perhaps something is wrong with my setup but at least certain that it should pick up the GPU.
