Khronos Releases OpenCL Spec

kpesler writes "Today, the Khronos Group released the OpenCL API specification (which we discussed earlier this year). It provides an open API for executing general-purpose code kernels on GPUs — so-called GPGPU functionality. Initially bolstered by Apple, the API garnered the support of major players including NVIDIA, AMD/ATI, and Intel. Motivated by inclusion in OS X Snow Leopard, the spec was completed in record time — about half a year from the formation of the group to the ratified spec."

The 80's called, they want their PRAGMA back

Why are all HPC languages targeting the GPU pretending that compiler technology stopped with C? I can understand wanting the low-level control, but not always. How about some higher level constructs to encapsulate the often repeated GROUPSIZE, group_id, local_id logic?

There's only one way of accessing memory that performs - so make the compiler enforce it, unless I explicitly want to use low-level API to do something fancy.
