»Code Challenge Announced At SC14

Today at SC14, the OpenMP Architecture Review Board (ARB) announced a Code Conversion Challenge. The Challenge is to users to bring in shared memory or accelerator code (C++ AMP, CUDA, OpenACC®, OpenCL®, …) from real applications. The ARB will then demonstrate how to write them in modern OpenMP.

The applications can be written in any parallel programming model, either shared-memory or accelerator based. The OpenMP ARB will convert the applications to OpenMP, with a focus on source to source conversion, especially of the parallel regions of interest.

OpenMP, one of the most-capable high-level parallel languages

The ARB aims to show that reasonable programs written in another parallel programming model (e.g., OpenCL, Co-Array-Fortran, OpenACC, CUDA, C++, C++AMP or Cilk) can be rewritten in OpenMP and thus that modern OpenMP is among the most-capable high-level parallel languages.

Submission of applications

Applicants are welcome to submit their applications on the site https://github.com/OpenMP/Challenge. If the submitter agrees, the application will be listed on the OpenMP web site. Discuss the code challenge on the OpenMP Code Challenge Forum.

We have designed modern OpenMP to be the best parallel language for the three general purpose languages C, C++ and Fortran, said Michael Wong, OpenMP CEO. It is a language that enables you to access all capabilities of your machine without dropping to another language. This Challenge will convince you of that or show us where we need to improve. Either way, the industry benefits.

»OpenMP in Clang/LLVM

The first talk at the LLVM developers’ meeting  October 28-29 is  OpenMP Support in Clang/LLVM: Status Update and Future Directions

  • What: The eighth meeting of LLVM Developers and Users.
  • When: October 28-29, 2014
  • Where: DoubleTree by Hilton - San Jose, CA

OpenMP Support in Clang/LLVM: Status Update and Future Directions
Alexey Bataev (Speaker) - Intel, Zinovy Nis (Speaker) - Intel
OpenMP is a well-known and widely used API for shared-memory parallelism. Support for OpenMP in Clang/LLVM compiler is currently under development. In this talk, we will present current status of OpenMP support, what is done and what remains to be done, technical details behind OpenMP implementation. Also, we will elaborate on accelerators and pragma-assisted SIMD vectorization, introduced in the latest 4.0 edition of the OpenMP specifications.

CALL FOR PAPERS

10th International Workshop on OpenMP IWOMP 2014 Using and Improving OpenMP for Devices, Tasks and More September 28-30, 2014 SENAI CIMATEC - Salvador, Bahia, Brazil http://www.iwomp.org/

The International Workshop on OpenMP 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. IWOMP 2014 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 session(s) during which research ideas and results will be presented and discussed.

Technical Paper Submission and Publication

Submissions of unpublished technical papers detailing innovative, original research and development related to OpenMP are solicited. All topics related to OpenMP are of interest, including OpenMP performance analysis and modeling, OpenMP performance and correctness tools, proposed OpenMP extensions, and OpenMP applications in any domain (e.g., scientific computation, video games, computer graphics, multimedia, information retrieval, optimization, text processing, data mining, finance, signal and image processing and numerical solvers). Advances in technologies, such as multi-core processors and OpenMP devices (accelerators such as GPGPUs, DSPs or FPGAs), Multiprocessor Systems on a Chip (MPSoCs), and recent developments in OpenMP itself (e.g., tasking) present new opportunities and challenges for software and hardware developers.  IWOMP 2014 particularly solicits submissions in these areas as well as ones that discuss how to apply OpenMP to additional models of parallelism such as event loops. Submitted papers for review should be limited to 12 pages and follow LNCS guidelines:

  • Updated submission deadline is May 25, 2014
  • Authors of accepted papers will be asked to prepare a final paper of up to 15 pages. As in previous years, IWOMP 2014 will publish formal proceedings of the accepted papers in Springer Verlag’s LNCS series.

Important Dates:

  • Paper submission deadline: May 25, 2014  (*UPDATED*)
  • Notification of acceptance: June 6, 2014
  • Tutorial and workshop in Salvador, Bahia, Brazil: September 28-30, 2014

»PPCES 2014 : HPC Seminar and Workshop : March 10-14

Parallel Programming in Computational Engineering and Science
Monday, March 10 - Friday, March 14, 2014vin Aachen, Germany

This event will continue the tradition of previous annual week-long events that take place in Aachen every spring since 2001.

Throughout the week we will cover a wide spectrum of topics, ranging from serial  programming (Monday) to parallel programming using MPI (Tuesday) and OpenMP (Wednesday) in both Fortran and C/C++ as well as performance tuning.  Furthermore, we will introduce the participants to modern features of the OpenMP standard like vectorisation and programming for accelerators and for the Many Integrated Core (MIC) Architecture (Thursday) as well as GPGPU programming with OpenACC (Friday). Hands-on exercises for each topic will be provided, which should not discourage you from working on your own code.

The topics are presented in a modular way, so that you could pick specific ones and register for the particular days only in order to let you invest your time as efficiently as possible.

Attendees should be comfortable either 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.

There is no seminar fee. All other costs (e.g. travel, hotel, and consumption) are at your own expenses.

Allocation is on a first come, first served basis, since the seminar room is of limited capacity. Please register separately for each session you would like to attend.

http://www.rz.rwth-aachen.de/ppces

The registration deadline is March 3, 2014.

The event is kindly sponsored by the Bull company.

The OpenMP API supports multi-platform shared-memory parallel programming in C/C++ and Fortran. The OpenMP API defines a portable, scalable model with a simple and flexible interface for developing parallel applications on platforms from the desktop to the supercomputer.
