Sadly, Intel's integrated-GPU OpenCL still doesn't support Linux, and only just started supporting OS X in 10.9 Mavericks[1]. Usually Intel's Linux GPU support is great; I don't know why this is different.

(Intel do have a Linux OpenCL implementation for Xeon CPU cores and Xeon Phi coprocessor[2], which doesn't help me much. On-CPU OpenCL is fine but hardly faster than regular CPU code, and Phi coprocessors aren't very common currently.)
