NEWSLETTER OF THE OPENMP ARB

Edition: Spring 2006

This is the quarterly newsletter of the OpenMP Architecture Review Board. It is based on the discussions in the OpenMP ARB conference calls of the previous quarter, and on current activities in the world of OpenMP. You can find general OpenMP-related links at the tail of the newsletter.

* IWOMP 2006 will be held in Reims, France.

IWOMP 2006 (the International Workshop on OpenMP) will be held in Reims, FRANCE. The workshop will be a great opportunity for learning more about OpenMP, for practical experience and interaction between OpenMP users and developers. In keeping with the objectives and format of the previous workshops, IWOMP 2006 will feature two distinct parts. The first part, which will take place in the Pommery Castle, will consist of presentations of technical papers and panels. The second part, which will take place at Reims University, will provide attendees the opportunity to learn OpenMP through a tutorial that will include several real-life case studies or to improve the performance of their applications through a hands-on laboratory experience.

Hotel booking is now open. The deadline for using the IWOMP block of rooms is April 28, 2006. You can find more information at

http://www.iwomp.org.

The registration is now open, and deadline for early registration is May 15, 2006.

* OpenMP 3.0 development is on-going

There are two active subgroups; one on task queues and one on hardware abstractions. The task queue subgroups is focusing on semantics, and is working on combining the 3 proposals. The hardware abstraction subgroup is focusing on the mapping of threads to hardware resources. One of the items under discussion is the subdivision of threads to get better locality. Multicore and hyperthreading issues will be addressed.

* An OpenMP validation suite is available for download

The OpenMP validation suite is a collection of C and Fortran programs with OpenMP directives that were designed to validate the correctness of an OpenMP implementation. It is a joint effort of the High Performance Computing Center Stuttgart and the University of Houston.

The suite is designed to cover the 2.5 version of the OpenMP standard. This version not only merges the Fortran and C/C++ language binding from the former version 2.0, but it also contains a number of clarifications or more detailed specifications. Currently the suite consists of more than 50 different tests, each testing differentconstructs. You can find more information and download the suite at:

* Dr Biswas of NASA Ames has been elected to the Board of Directors

of the OpenMP ARB

Dr. Biswas is currently acting chief of the NASA Advanced Supercomputing (NAS) Division, which has hosted one of the world

fastest supercomputers, Columbia. He has been elected to the Board of Directors of the OpenMP ARB. The members of the Board are now:

Josh Simons (Sun), Sanjiv Shah (Intel), Kohichiro Hotta (Fujitsu), Charles Grassl (IBM), and Rupak Biswas (NASA Ames).

Dr. Biswas is a nationally recognized expert in the areas of parallel programming models and paradigms; benchmarking and performance characterization of emerging and innovative architectures for high-end computing (HEC) systems; novel partitioning and load balancing techniques for large-scale computational science problems; and scheduling algorithms for distributed computing environments. He lead a group of NASA scientists and collaborators from other institutes to conduct benchmarking and performance characterization of several HEC systems using various parallel programming models and paradigms. His earlier work on OpenMP has been illustrated by the paper on

"Parallelization of a Dynamic Unstructured Application Using Three Leading Paradigms," which was awarded the best paper of SC99.
