Big Ideas in HPC

By Michael Feldman

July 23, 2009

When you cover the high performance computing community as I do, it can be easy to get lost inside our little corner of the world. This is especially true if you just talk to HPC vendors all day. Of course, the whole reason to use cutting-edge computing in the first place is to solve big problems in the real world. And some of these represent the most interesting challenges of the day: climate change, genomics, the nature of the universe, and artificial intelligence, to name just a few.

I was reminded of the last topic because of presentation this week by Henry Makram, director of the Blue Brain Project, based in Lausanne, Switzerland. The project’s goal is to simulate mammalian-style brains in silico. The researchers just happen to use a 10,000-processor IBM Blue Gene supercomputer to get the job done. To date, they have been able to simulate about 50,000 neurons of a rat’s neocortical column in something approaching real time.

At the TED Global conference in Oxford, England, on Wednesday, Makram predicted that within 10 years they’ll be able to simulate a human brain (presumably with a much more powerful computer than the current Blue Gene). In principle, if the model is accurate, the artificial brain should respond like a real human, or at least like Dick Cheney. According to a BBC report, Makram quipped “And if we do succeed, we will send a hologram to TED to talk.”

I bring this up not so much to spotlight the Blue Brain work, which is certainly fascinating in its own right, but to point to the rarity of HPC visibility in venues like the TED conference. TED (which stands for Technology, Entertainment, Design) is quite an interesting organization. It’s a non-profit, established in 1996 by Chris Anderson, editor-in-chief of Wired magazine and author of The Long Tail. The organization is all about the confluence of technology, science, art, and culture. Its catch-phrase is “Ideas Worth Spreading.”

Besides hosting conferences, TED maintains a Web site that hosts blogs and video presentations of movers and shakers in the government, arts and sciences. The content manages to be intellectual and fun at the same time. It’s certainly not a melting pot of content like you find on YouTube. Another Web site along the same lines, although somewhat newer, is Big Think. I peruse this one from time to time and always find something worth watching.

What’s hard to find at TED or Big Think are the HPC visionaries. This may be because most of the top-end academicians in high performance computing are used to attending the same ACM and IEEE sponsored events every year. At the other end are the vendors, which go mostly to trade shows. HPC users, like Makram, may venture further afield, but are usually focused on talking about their applications rather than the wonders of supercomputing. That’s understandable.

I don’t want to leave you with the incorrect impression that our community is totally invisible. Besides the Blue Brain presentation at this week’s conference, I also came across an interesting TED video of something called the AlloSphere. It’s a 3D immersive theater at the University of California, Santa Barbara that uses visualization and audio to present complex data. Rather than trying to describe it further, I’ve inserted the 7-minute video below. If you want more information about the project and the woman behind it, follow this link.

HPE-SGI to Tackle Exascale and Enterprise Targets

November 22, 2016

At first blush, and maybe second blush too, Hewlett Packard Enterprise’s (HPE) purchase of SGI seems like an unambiguous win-win. SGI’s advanced shared memory technology, its popular UV product line (Hanna), deep vertical market expertise, and services-led go-to-market capability all give HPE a leg up in its drive to remake itself. Bear in mind HPE came into existence just a year ago with the split of Hewlett-Packard. The computer landscape, including HPC, is shifting with still unclear consequences. One wonders who’s next on the deal block following Dell’s recent merger with EMC. Read more…

D-Wave SC16 Update: What’s Bo Ewald Saying These Days

November 18, 2016

Tucked in a back section of the SC16 exhibit hall, quantum computing pioneer D-Wave has been talking up its new 2000-qubit processor announced in September. Forget for a moment the criticism sometimes aimed at D-Wave. This small Canadian company has sold several machines including, for example, ones to Lockheed and NASA, and has worked with Google on mapping machine learning problems to quantum computing. In July Los Alamos National Laboratory took possession of a 1000-quibit D-Wave 2X system that LANL ordered a year ago around the time of SC15. Read more…

HPE Gobbles SGI for Larger Slice of $11B HPC Pie

August 11, 2016

Hewlett Packard Enterprise (HPE) announced today that it will acquire rival HPC server maker SGI for $7.75 per share, or about $275 million, inclusive of cash and debt. The deal ends the seven-year reprieve that kept the SGI banner flying after Rackable Systems purchased the bankrupt Silicon Graphics Inc. for $25 million in 2009 and assumed the SGI brand. Bringing SGI into its fold bolsters HPE's high-performance computing and data analytics capabilities and expands its position... Read more…

Beyond von Neumann, Neuromorphic Computing Steadily Advances

March 21, 2016

Neuromorphic computing – brain inspired computing – has long been a tantalizing goal. The human brain does with around 20 watts what supercomputers do with megawatts. And power consumption isn’t the only difference. Fundamentally, brains ‘think differently’ than the von Neumann architecture-based computers. While neuromorphic computing progress has been intriguing, it has still not proven very practical. Read more…
