NEWSLETTER OF THE OPENMP ARB
Edition: February 2003

This is the monthly newsletter of the OpenMP Architecture Review
Board. It is based on the discussions in the OpenMP ARB conference
calls of the previous month, and on current activities in the
world of OpenMP.

The website of the OpenMP ARB is http://www.openmp.org. The web
site of the OpenMP User's Group cOMPunity is http://www.compunity.org.

* The dates of WOMPAT 2003 are now set on 26-27 June 2003.

WOMPAT 2003 will be held on June 26-27 in lovely Toronto, Canada. Their
web site is http://www.eecg.toronto.edu/wompat2003/. The deadline for
submission of extended abstracts is 21 February 2003.

* The SPEC HPC2002 benchmark suite has been released

A new benchmark suite based on OpenMP and MPI has been released by
the SPEC High-Performance Group. The web site is
http://www.spec.org/hpg/hpc2002. This benchmark suite is in addition
to the pure OpenMP benchmark suite OMP2001, also released by SPEC at
http://www.spec.org/hpg/omp2001.

* Rectangular loop collapsing added to list of OpenMP 3.0 recommended
features

The OpenMP Futures group recommends that OpenMP 3.0 should support
automatic collapsing of rectangular loops, viz. specifying one
directive that collapses and parallelizes the following nested do
loops:

       do i = 1, N1
             do j = 1, N2
               ! loop body that uses i and j
             end do
        end do

The committee has looked at automatic collapsing of non-rectangular
loops, and has decided NOT to recommend this for addition in OpenMP
3.0.

* Discussion on performance tool and debugging APIs on-going

The latest telecon focused on the question of whether performance
tools and debuggers could be properly served by a unified
interface. We concluded that it is better to keep the interfaces
separate. The biggest reason is that they work in fundamentally
different ways - the performance interface works within the
application while the debugger interface is external. Therefore, it
was decided that we will work towards separate interfaces. The OpenMP
Tools group will develop three sets of specifications: one for
performance tools (primarily focused on inserting instrumentation);
one for debuggers; and one for information-querying mechanisms. It was
agreed that POMP will serve as the initial strawman for the first.

* PDPTA'03 has a call for papers.

The 2003 International Conference on Parallel and Distributed
Processing Techniques and Applications (PDPTA'03) has a call for
papers. Papers on OpenMP are solicited. Please go to
http://www.ashland.edu/~iajwa/conferences/2003/PDPTA/pdpta.html.
