Exascale Progress Meter – Are We Moving in the Right Direction?


In this special feature, Mike Bernhardt looks at our current progress towards Exascale computing, a future milestone of supercomputing 10^18 flops.

Blue Waters and XSEDE to Collaborate

The Blue Waters petascale computing project at NCSA and the Extreme Science and Engineering Discovery Environment (XSEDE) have signed a collaborative agreement, bringing together the National Science Foundation’s two largest cyberinfrastructure projects.

ISC Cloud’13 Focused on Engineering & Science Simulation


There is a strong and growing wave of interest (and not just from vendors) in cloud-based engineering simulation. I met with numerous end users, especially from smaller and mid-market companies, who desperately need a more cost-effective way to perform engineering work, in terms of both computation and software licensing.

Rich Brueckner to Discuss Big Data Trends at October Carrier Event


Hurricane Electric will host its next Carrier Networking Event on Wednesday, October 30. The event will feature Rich Brueckner from insideBIGDATA. “We are thrilled to welcome Rich to our increasingly popular Carrier Networking Event. Big Data stands out in the industry as a topic continually growing in importance and we look forward to Rich sharing his extensive knowledge and thoughts on future trends.”

The Gap Between High Performance and High Availability

Clive Longbottom contrasts the architectures of high-performance and high-availability clusters. And while users may request the best of both worlds, the end game often comes down to money.

MERIL Database to Chart European Research Infrastructure

A public database dubbed MERIL (Mapping of the European Research Infrastructure Landscape) has been launched with the aim of providing a comprehensive inventory of high quality research infrastructures in Europe across all scientific domains, and accessible through an interactive online portal.

NAND Flash, What Comes Next?


The recent Flash Memory Summit in Santa Clara included some notable announcements.

Power to the People


In this special guest feature, Michael Feldman and Chris Willard from Intersect360 Research look at the newly launched OpenPOWER Consortium from IBM.

Software Development Standards for Next-gen HPC Systems

John Barr asks what standard approach can the industry agree on to make next-generation HPC systems easier to program?

When the architecture of high-performance computing (HPC) systems changes, the tools and programming paradigms used to develop applications may also have to change. We have seen several such evolutions in recent decades, including the introduction of multiprocessors, the use of heterogeneous processors to accelerate applications, vector processors, and cluster computing.

These changes, while providing the potential for delivering higher performance at lower price points, give the HPC industry a big headache. That headache is brought on by the need for application portability, which in turn leverages standard development tools that support a range of platforms. Without software standards supporting emerging platforms, independent software vendors (ISVs) are slow to target these new systems, and without a broad base of software the industry pauses while the software catches up.

An example of this was the transition from complex, expensive shared memory systems to proprietary distributed memory systems, and then to clusters of low cost commodity servers. When each new system had its own message passing library, ISVs were reluctant to port major applications. It was only when MPI was widely accepted as the standard message passing library that the body of applications available for clusters started to grow, and cluster computing became the norm in mainstream HPC.

So the burning question is: What standard approach can the industry agree on to make next generation HPC systems easier to program, and therefore more attractive for ISVs to support?
