In recent years, OpenMP has shifted from being solely focused on shared- memory systems to also include accelerators, embedded systems, multicore and real-time systems. Today the OpenMP Architecture Review Board (ARB) releases a new Mission Statement to formalize this change.
A technical report on directives for attached accelerators was first released in 2012, and subsequently, a full revision of the standard, OpenMP 4.0, was released in 2013, which included support for accelerators, SIMD constructs to vectorize both serial as well as parallelized loops, error handling, thread affinity, and tasking extensions.
Following these releases, the OpenMP ARB is ready for a new mission statement. The old mission statement was focused on shared-memory systems, but the new Mission Statement broadens this mandate to “Standardize directive-based multi-language high-level parallelism that is performant, productive and portable.”
“The new Mission Statement for OpenMP is the result of a collaborative consultation between members, industry, and academia”, said Michael Wong, OpenMP CEO. “It recognizes the changing landscape of parallelism by broadening our mandate to cover more types of architecture, be more robust, responsive, and dynamic while remaining firmly committed to our pedigree. With our firm footing now supporting accelerators and embedded systems, we are open to begin further exploration into more affinity, deeper task dependencies, full error-model, NUMA-access, FPGA, transactional memory, asynchronous and even-driven programming, inter-nodal and intra-nodal interoperability.”
February 13, 2014 - Champaign, Illinois - The OpenMP ARB, a group of leading hardware and software vendors and research organizations developing the OpenMP API specification for shared-memory parallelization, appointed Dieter an Mey to its Board of Directors. Dieter brings a wealth of experience as an OpenMP user to the Board.
Dieter an Mey leads the High Performance Computing team of the IT Center RWTH Aachen University in Germany. He has a 30+ year track record in HPC with an emphasis on user support and services. Ever since vectorization and message passing and the release of the first OpenMP API specification in 1997, Dieter and his group have actively participated in the OpenMP community. He is co-author of numerous publications on OpenMP programming and productivity.
“I believe Dieter will bring a much needed non-commercial viewpoint to the Board, as well as a non-US viewpoint”, said Michael Wong, OpenMP CEO. “He has been a long-time, active OpenMP proponent who is widely respected within the OpenMP community.”
Dieter joins Josh Simons of VMware, Sanjiv Shah of Intel, Andy Fritsch of Texas Instruments and Partha Tirumalai of Oracle on the OpenMP Board of Directors.
An update to the OpenMP 4.0 Examples document is now available. It adds new examples that demonstrate use of the proc_bind clause to control thread binding for a team of threads in a parallel region. Also, new examples for the taskgroup construct.
