GCC 5.0 Provides Full Cilk Plus Support
GNU has announced that GCC 5.0 will provide full support for Cilk Plus. Cilk Plus is an extension to the C and C++ languages to support data and task parallelism on multi-core, vector and Intel Xeon Phi coprocessors.It is reputed to be quite efficient and looks to be easy to use. The Intel icc compiler has supported Cilk Plus for years. GNU support now makes Cilk Plus available … [Read more...]
Intel SPMD Compiler (ISPC) for Xeon and Xeon Phi
When #pragma SIMD is not enough, companies and projects such as Intel, Embree, Dreamworks, Pixar, Autodesk, and SURFsara are looking to the freely available Intel SPMD Program Compiler (ispc) to achieve high vector performance on Xeon and Intel Xeon Phi devices. ISPC is LLVM-based and designed to exploit Intel SIMD architectures … [Read more...]
Commercial OpenCL! SPIR 2.0 Protects IP Yet Allows Powerful, Portable, Source Code Free Kernels
It used to be that portable OpenCL applications required shipping source code for the parallel kernels with the application. In this way, the kernel source code could be compiled for any device at any time in the future. Bad news from an IP protection point of view! The alternative was to pre-compile the kernels thus bloating applications and limiting the devices the OpenCL … [Read more...]
