  • One million trillion ‘flops’ per second targeted by new Institute for Advanced Architectures

    Our focus is what we call commercial high performance computing, as a simultaneous acknowledgment of and differentiation from traditional HPC. We are not the same, as HPC is all about FORTRAN and super grids, and C-HPC is all about data and whole file analytic processing. But we acknowledge the tremendous advances HPC is making, and we are grateful for the trickle-down of technology and research.

    This article outlines a very ambitious plan and a major new initiative to attack it. Of particular note: “In order to continue to make progress in running scientific applications at these [very large] scales,” says Jeff Nichols, who heads the Oak Ridge branch of the institute, “we need to address our ability to maintain the balance between the hardware and the software. There are huge software and programming challenges and our goal is to do the critical R&D to close some of the gaps.”

  • Multicore puts screws to parallel-programming models

    This article covers the creation of a new effort to make sure that software will be available as new, heterogeneous multicore designs are developed. Is this a response to the challenges of today? Most likely. ""The industry is in a little bit of a panic about how to program multicore processors, especially heterogeneous ones," said Chuck Moore, a senior fellow at AMD now serving as chief architect of the company's so-called accelerated computing initiative. "To make effective use of multicore hardware today, you need a PhD in computer science. That can't continue if we want to enable heterogeneous CPUs."

  • CPU designers debate multi-core future

    This article highlights the continuing difference in views and visions for the future of multicore as discussed at a panel on the topic at the International Solid State Circuits Conference. Often, we think that the other guys know where things are going, but this shows that there is uncertainty in their domain as well.

    "As for software, the time to market has been long in the past, but we can't afford to let that be the case in the future."

    "With multi-core it's like we are throwing this Hail Mary pass down the field and now we have to run down there as fast as we can to see if we can catch it"

  • The Next Step in Multicore

    This article previews some previously known but unannounced processor products. But it is also the first article I have seen that gently hints at the consequence of dawdling in the migration to parallelization.

    "At this point, it’s hard to imagine that any software developer is not aware of the multicore challenge. But it’s fair to say that few have openly publicized new 'multicore friendly' versions of their applications. If they don’t start to show up soon, there could be a lot of angry customers out there."
