HAMBURG, Germany, June 22 -- CAPS entreprise and Pathscale today announced that OpenHMPP - a non-profit association of academic, research, and industry partners which mission is to work with and for the HPC community to make HMPP directives a world-class open standard -- is now live!
Since last year, CAPS and Pathscale have been coordinating their effort to make HMPP directives an Open Standard denoted OpenHMPP. This initiative aims at creating a community effort for proposing a directive manycore programming interface and thus capitalizing on existing experiences with HMPP.
"CAPS has always been committed in delivering to users solutions that will secure their software investment. We think the directive approach is definitely the best way to meet this issue. Now, with the open standard and the software companies adopting HMPP, our customers feel confident in their choice." declares Laurent Bertaux, CAPS CEO. The HMPP directives, initially developed by CAPS, have been designed and used for more than 3 years by major HPC leaders. As a high level of abstraction for programming GPUs in scientific applications, HMPP preserves customers' software assets by keeping applications portable. The HMPP directive-based programming model offers a powerful syntax to efficiently offload computations on hardware accelerators and to optimize data movement.
HMPP directives describe remote procedure call (RPC) on an accelerator device (e.g. GPU) or more generally a set of cores. The directives annotate C or Fortran codes to describe two sets of functionalities: the offloading of procedures (denoted codelets) onto a remote device, the optimization of data transfers between the CPU main memory and the accelerator memory.
As more and more industry leaders, ALLINEA Debugger now supports HMPP directives. "With the recent release of Allinea DDT 3.0, it is now possible to debug your NVIDIA GPU application at a high level", says Jacques Philouze, ALLINEA Vice President Sales & Marketing.
The OpenHMPP consortium oversees the HMPP directives specification, produces and approves new versions of the specification. In accordance with its vision involving participation and knowledge sharing, OpenHMPP works towards providing programmers with a portable, scalable directive-based programming model for developing parallel applications on manycore platforms.
OpenHMPP group has several top-level goals:
A set of core partners (CAPS, GENCI, ICHEC, INRIA, PathScale…) are currently in discussion to set up the non-profit organization that will own the OpenHMPP brand and run its evolutions. This organization will gather technology providers, application developers as well as ISVs.
"It's exciting for PathScale to be a founding member in the OpenHMPP organization." Comments Christopher Berström, CTO at Pathscale. "Almost two years ago Francois Bodin (CTO at CAPS) and I started the idea to make the HMPP directives an open standard, but now a clear path for broad collaboration and adoption is possible for anyone interested."

In quieter times, sounding the bell of funding big science with big systems tends to resonate further than when ears are already burning with sour economic and national security news. For exascale's future, however, the time could be ripe to instill some sense of urgency....
In a recent solicitation, the NSF laid out needs for furthering its scientific and engineering infrastructure with new tools to go beyond top performance, Having already delivered systems like Stampede and Blue Waters, they're turning an eye to solving data-intensive challenges. We spoke with the agency's Irene Qualters and Barry Schneider about..
Large-scale, worldwide scientific initiatives rely on some cloud-based system to both coordinate efforts and manage computational efforts at peak times that cannot be contained within the combined in-house HPC resources. Last week at Google I/O, Brookhaven National Lab’s Sergey Panitkin discussed the role of the Google Compute Engine in providing computational support to ATLAS, a detector of high-energy particles at the Large Hadron Collider (LHC).

The study of climate change is one of those scientific problems where it is almost essential to model the entire Earth to attain accurate results and make worthwhile predictions. In an attempt to make climate science more accessible to smaller research facilities, NASA introduced what they call ‘Climate in a Box,’ a system they note acts as a desktop supercomputer.

At some point in the not-too-distant future, building powerful, miniature computing systems will be considered a hobby for high schoolers, just as robotics or even Lego-building are today. That could be made possible through recent advancements made with the Raspberry Pi computers.

When it comes to cloud, long distances mean unacceptably high latencies. Researchers from the University of Bonn in Germany examined those latency issues of doing CFD modeling in the cloud by utilizing a common CFD and its utilization in HPC instance types including both CPU and GPU cores of Amazon EC2.
