IWOMP 2013 Canberra

9th International Workshop on OpenMP — September 16-18, 2013
Canberra, AUSTRALIA

The »International Workshop on OpenMP (IWOMP) is an annual workshop dedicated to the promotion and advancement of all aspects of parallel programming with OpenMP. It is the premier forum to present and discuss issues, trends, recent research ideas and results related to parallel programming with OpenMP. The international workshop affords an opportunity for OpenMP users as well as developers to come together for discussions and sharing new ideas and information on this topic.

The deadline for paper submissions has been extended to May 10th.

IWOMP 2013 will be a three-day event. The first day will consist of tutorials focusing on topics of interest to current and prospective OpenMP developers, suitable for both beginners as well as those interested in learning of recent developments in the evolving OpenMP standard. The second and third days will consist of technical papers and panel sessions during which research ideas and results will be presented and discussed.

»OpenMP 4.0 Second Release Candidate Now Available

Release Candidate 2 of the OpenMP 4.0 API specifications currently under development is now available for public discussion.

In addition to a number of corrections and clarifications to the specifications, Release Candidate 2 includes the following major enhancements:

  • Initial accelerators support: Device Data Environments (p16), target constructs (p68: target, target data, target update, declare target, teams, distribute; p151: map clause; and associated runtime routines (p191).)
  • Task dependency support through the new depend clause. (p91)
  • Initial error model support through cancel and cancellation point constructs to request cancellation of specified region types and to declare a user-defined cancellation point to  check for cancellation requests.. (Section 2.13, p116: Cancellation Constructs)
  • Support for Array Sections in C and C++ as well as adding sectioning support for Fortran. (Section 2.4, p36: Array Sections)
  • Extends declare simd to allow multiple declarations. (p64)
  • New environment variable OMP_DISPLAY_ENV instructs the runtime to display the OpenMP version number and initial values during initialization. (p219)
  • Additional enhancements to support Fortran 2003.

These are in addition to enhancements introduced in RC1: thread affinity, initial support for Fortran 2003, SIMD constructs to vectorize both serial and parallelized loops, TASKGROUP, user-defined reductions, and sequentially consistent atomics.

The OpenMP ARB plans to follow this public discussion period with the finalized full 4.0 API specifications later this year.

The 4.0 Release Candidate API specifications (4.0 RC2, 4.0 RC1) and the Technical Report (TR1) PDFs can be downloaded from the »OpenMP Specifications Page.

»PPCES 2013 : HPC Seminar and Workshop : March 11-15

PPCES 2013: Parallel Programming in Computational Engineering and Science HPC Seminar and Workshop

Monday, March 11 - Friday, March 15, 2013 at the Center for Computing and Communication RWTH Aachen University, Germany

This event will continue the tradition of previous annual week-long events taking place in Aachen every spring since 2001. Throughout the week, we will cover serial (Monday) and parallel programming using MPI (Tuesday) and OpenMP (Wednesday) in Fortran and C / C++ as well as performance tuning addressing both Linux and Windows platforms. Furthermore, we will introduce the participants to GPGPU programming (Thursday) and programming the brand new Intel Xeon Phi processor (Friday) and provide ample opportunities for hands-on exercises including a “bring-your-own-code” session on Friday. These topics are presented in a modular way, so that you can choose, pick and register for single days in order to let you invest your time as efficiently as possible.

Attendees should be comfortable with C/C++ or Fortran programming and interested in learning more about the technical details of application tuning and parallelization. The presentations will be given in English.

The seminar is free. Allocation is on a first come, first served basis, as we are limited in capacity. Please register separately for any session you intend to participate. Go to: http://www.rz.rwth-aachen.de/ppces for more information. The event is sponsored by the companies Bull and NVIDIA.
