This is an OpenPGP/MIME signed message (RFC 2440 and 3156) --------------enigDA220183AD5D429D7C88391E Content-Type: multipart/mixed; boundary="------------020905080102060901040901" This is a multi-part message in MIME format. --------------020905080102060901040901 Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: quoted-printable Hello. FreeBSD has fallen back far behind the standards of modern scientific computing and I dsperately look for solutions having OpenCL support on FreeBSD anyway. I stumbled into this project recently: FreeOCL at http://code.google.com/p/freeocl/ or the sources located at http://code.google.com/p/freeocl/downloads/detail?name=3DFreeOCL-0.3.6-sr= c.tar.gz&can=3D2&q=3D For your convenience, please find my naive attempt of a port attached to this email. Well, I tried LLVM/CLANG, but Cmake of the sources fairly fails many checks especuially for OpenMP. Using clang++ requisites the usage of the new libc++ (CXXFLAGS+=3D -stdlib=3Dlibc++). But this fails with this erro= r: [...] [ 17%] Building CXX object src/CMakeFiles/FreeOCL.dir/codebuilder.cpp.o In file included from /usr/ports/devel/freeocl/work/FreeOCL-0.3.6-Source/src/codebuilder.cpp:26= : /usr/ports/devel/freeocl/work/FreeOCL-0.3.6-Source/src/parser/parser.h:11= 8:15: error: no viable conversion from 'std::__1::basic_istream<char>' to 'const bool' const bool ok =3D in.get(c); ^ ~~~~~~~~~ /usr/ports/devel/freeocl/work/FreeOCL-0.3.6-Source/src/codebuilder.cpp:44= 4:13: warning: 70 enumeration values not handled in switch: 'VOID', 'BOOL', 'HALF'...

More disturbing is the use of gcc-4.6 via USE_GCC=3D 4.6+ The error is then a compalin about a missing include file atomic_ops.h which is located in the abandoned KSE facility of the kernel, so the includes seem not to be installed anymore - but since I'm not involved in the development, I can only guess and ask the people here. Maybe some experienced freeBSD developers with the same need for OpenCl is willing to pick up this and help a bit. Well, as far as I see, the FreeOCL project of Roland Borchard is a OpenCL library for CPU usage. As far as I can understand, if we on FreeBSd could have a library "libOpenCL" as this is usually installed by the nVidia BLOB drivers on Linux for the use of OpenCL/GPGPU support with their GPUs, this would fill a still painfull open gap in FreeBSD as a scientific development platform. There is still no suitable compiler for OpenCL out here for freeBSD, but I have still the hope that LLVM can provide such a thing in the near futu= re. I cross post this posting also to "performance" in the hope finding some people attracted and "lurd" into this subject. Regards, O.
