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. The
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
