The OpenMP Architecture Revew Board has approved the 3.0 specifications. The 3.0 draft specifications were out for public review from October thru January. The final 3.0 specs is now available. It corrects a number of typos, clarifies some issues raised during the review period, and contains completed appendicies and lists [...]
Sessions discussing OpenMP at ISC 08 in Dresden in June: Harnessing the Potential of Multicore/Manycore Processors MPI has been the prevailing programming interface for parallel computing. With the widespread use of multi/many-core computers, OpenMP will gain in importance. Professor Lutz Gross, the Director of High Performance Computing in the Earth [...]

»SLIRP is a vectorizing code generator aimed primarily at simplifying the process of creating modules for the S-Lang scripting language. It supports making C, C++, and Fortran code callable directly from the S-Lang interpreter and can automatically vectorize functions to take advantage of the abilities of S-Lang. SLIRP can also [...]
The SC07 OpenMP BOF was held at the SC07 conference in Reno on November 15, 2007. There were about 70 attendees. Mark Bull of EPCC presented the draft OpenMP 3.0 standard. Marty Itzkowitz presented a modification to the Performance API to reduce overhead for short parallel regions. Both presentations are [...]
