HPCwire caught up with Wellein and asked him to preview some of the themes of his upcoming talk and expound on his philosophy of programming for performance in the multicore era.

Version 4.0 will include the functionality that was implemented in OpenACC, the accelerator API that splintered off from the OpenMP work, as well as offer additional support beyond that. The new standard is expected to become the the law of the land sometime in early 2013.
Kickstarter investment model notches another high-tech success.

The idea for the project was presented to the President of Russia, Dmitry Medvedev, back in 2009. The work was immediately approved and scheduled for the 2010–2012 timeframe, with the implementation assigned to Lomonosov Moscow State University, the university that hosts the largest supercomputing center of Russia.

This article will discuss a range of potentially interesting heterogeneous systems for high performance computing, why programming them is hard, and why developing a high level programming model is even harder.

But retrofitting existing programming languages for parallel programming is underway. We can compare and contrast retrofits by looking at four key features, five key qualities, and the various implementation approaches.
This week Intel unveiled its upmarket version of its Cluster Studio offering aimed at performance-minded MPI application developers. Called Cluster Studio XE, the jazzed-up developer suite adds Intel analysis tools to make it easier for programmers to optimize and tune codes for maximum performance. It also includes the latest compilers, runtimes, and MPI library to keep pace with the new developments in parallel programming.
