I read this week this article on Phoronix: http://www.phoronix.com/scan.php?page=article&item=amd_r600g_llvm&num=1
Well, it looks promising to me in terms of having also OpenCL capabilities for GPGPU, but as the report says, the code is not finished and still in a very preliminary stage. What is the opinion of the FreeBSD people about this approach? Does the Gallium3D/Mesa driver with LLVM have the ability to bring professionality of HPC/GPGPU to FreeBSD? Or is it a dead end? I'm not familiar with the details of what's necessary for compiling executables for a specific GPU but the compiler, as far as I know, especially the code generator, needs to know about chip's internal and so I fear it's like nVidia's chips a black box.
