C++ SIMD parallelism with Intel Cilk Plus and OpenMP 4.0

by Georg Zitzlsberger

From the talk description:

Performance is one of the most important aspects that comes to mind if deciding for a programming language. Utilizing performance of modern processors is not as straight forward as it has been decades ago. Modern processors only rarely improve serial execution of applications by increasing their frequency or adding more execution units.

OpenMP* Support in Clang/LLVM: Status Update and Future Directions --Alexey Bataev & Zinovy Nis

A status update for the work done on OpenMP for Clang/LLVM and future directions presented at the 2014 LLVM Developers' Meeting. The slides are also available here.

OpenMP* Support in Clang/LLVM: Status Update and Future Directions

OpenMP is a well-known and widely used API for shared-memory parallelism. Support for OpenMP in Clang/LLVM compiler is currently under development. In this talk, we will present current status of OpenMP support, what is done and what remains to be done, technical details behind OpenMP implementation. Also, we will elaborate on accelerators and pragma-assisted SIMD vectorization, introduced in the latest 4.0 edition of the OpenMP standard.
