Apart from the lack of suitable driver support from the GPU vendors, OpenCL also provides support for tha CPU as a "native" target. To provide even FreeBSD users, develeopers and scientists to develop software for OpenCL 1.2, it is necessary to have a working library to start with. The project "POCL", Portable OpenCL, provides via LLVM backend such a library for at least the "native" CPU target, as their website states: "Portable OpenCL is an open source implementation of the OpenCL standard which can be easily adapted for new targets. One of the goals of the project is improving performance portability of OpenCL programs, avoiding the need for target-dependent manual optimizations. A "native" target is included, which allows running OpenCL kernels on the host (CPU)." Source: https://launchpad.net/pocl >How-To-Repeat: This port has been successfully compiled on a most recent FreeBSD 10.0-CURRENT/amd64 system which has been completely compiled with CLANG 3.2 and LLVM 3.2 installed from ports devel/llvm-devel. The port also has been successfully compiled and installed on FreeBSD 9.1-PRE/amd64, also completely compiled with the CLANG (v 3.1) aboard and LLVM 3.1 installed from the port devel/llvm. The usefulness hasn't been approved, nor did I do benchmarks for the "native" CPU target. I hope this [roject, due to its LLVM backend, could gain more assistance and more attention. >Fix: Patch attached with submission follows: # This is a shell archive.

X XIn addition to producing an easily portable open source OpenCL Ximplementation, another major goal of the project is improving Xperformance portability of OpenCL programs with compiler Xoptimizations, reducing the need for target-dependent manual Xoptimizations. At the core of pocl is a set of LLVM passes Xused to statically parallelize multiple work-items with the kernel Xcompiler, even in the presence of work-group barriers. This enables Xparallelization of the fine-grained static concurrency in the work Xgroups in multiple ways (SIMD, VLIW, superscalar,...). X XThe code base is modularized to allow easy adding of new "device drivers" Xin the host-device layer. A generic multithreaded "target driver" is Xincluded. It allows running OpenCL applications on a host that supports Xthe pthread library with multithreading at the work group granularity. X XAn optimized kernel library is provided for x86_64. The generic Xunoptimized (no instruction set extensions used) version has been Xsuccessfully tested with an ARMv7 CPU under MeeGo, and with several Xapplication-specific TTA processors designed using the TCE toolset. X XOther feature highlights include (experimental) work group Xautovectorization (create vector instructions out of multiple Xwork-items) and a customized kernel buffer allocator. X XEven though the OpenCL 1.2 standard is not yet implemented fully and Xit contains known bugs, we now consider pocl ready for wider scale testing. Xpocl 0.6 compiles and runs successfully most of the Rodinia benchmark, Xall of ViennaCL test cases, and most of the OpenCL Programming Guide Xsamples.
