This is an OpenPGP/MIME signed message (RFC 2440 and 3156) --------------enigC31A0724EDD7B88BD20AF2FC Content-Type: text/plain; charset=ISO-8859-15 Content-Transfer-Encoding: quoted-printable I read this week this article on Phoronix: http://www.phoronix.com/scan.php?page=3Darticle&item=3Damd_r600g_llvm&num= =3D1 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.
