SC15 Preview: Exascale or Bust! - On the Road to ExaFLOPS with IBTA

November 17th, 2015


This year’s Supercomputing Conference is shaping up to be one of IBTA’s most comprehensive to date. Whether listening to industry experts debate future system tune ups or cruising the show floor learning from members one-on-one, event attendees are bound to leave revved up about how interconnect advancements will alleviate data management road blocks.

OK. OK. Enough with the car metaphors-read on, though, to see what IBTA’s got in store for you (including some enticing giveaways!):

Birds of a Feather Panel Session
, Nov. 17 at 12:15 p.m. (Room 18AB)

“The Challenge of a Billion Billion Calculations Per Second: InfiniBand Roadmap Shows the Future of the High Performance Standard Interconnect for Exascale Programs”

It’s no secret. The race to exascale is on-the exponentially increasing amounts of data bogging down systems demand such speed. The critical issues now? What technological changes will be required to support this new High Performance Computing (HPC) vision and is the industry ready to solve them? I’ll be joining Brandon Hoff to lead the following esteemed panelists through a discussion on interconnect capabilities and roadmaps that will deliver a billion billion calculations per second:

  • Ola Tørudbakken, Oracle
  • Gilad Shainer, Mellanox
  • Pavan Balaji, Argonne National Laboratory
  • Bob Ciotti, NASA

IBTA Update
, Nov. 18 at 5 p.m. (Booth 613)

Standards-based, multi-vendor solutions are transforming HPC. In the Mellanox booth, I’ll be presenting the latest developments in InifiniBand technology and shed light on what’s to come-proving why this interconnect standard powers some of the world’s fastest supercomputers.

Race to Exascale – Nations Vie to Build Fastest Supercomputer

September 28th, 2015

The race between countries to build the fastest, biggest or first of anything is nothing new – think the race to the moon. One of the current global competitions is focused on supercomputing, specifically the race to Exascale computing or a billion billion calculations per second. Recently, governments (President Obama’s Executive Order and China’s current lead in supercomputing) are allocating significant resources toward Exascale initiatives as they start to understand its vast potential for a variety of industries, including healthcare, defense and space exploration.

The TOP500 list ranking the top supercomputers in the world will continue to be the scorecard. Currently, the U.S. leads with 233 of the top 500 supercomputers, Europe with 141 and China with 37. However, China’s small portfolio of supercomputers does not mean it is not a significant competitor in the supercomputing space as China has the #1 supercomputer on the TOP500 list for the fifth consecutive time.

When looking to build the supercomputers of the future, there are a number of factors which need to be taken into consideration, including superior application performance, compute scalability and resource efficiency. InfiniBand’s compute offloads and scalability makes it extremely attractive to supercomputer architects. Proof of the performance and scalability can be found in places such as the HPC Advisory Council’s library of case studies. InfiniBand makes it possible to achieve near linear performance improvement as more computers are connected to the array. Since observers of this space expect Exascale systems to require a massive amount of compute hardware, InfiniBand’s scalability looks to be a requirement to achieve this goal.

As the race to supercomputing speeds up we expect to see a number of exciting advances in technology as we shift from petaflops to exaflops. To give you an idea of how far we have come and where we are heading here is a comparison from the speed of computers that powered the race to space and the goals for Exascale.

Speeds Then vs. Now – Race to Space vs. Race to Supercomputing

  • Computers in 1960s (Speed of the Race to Space): Hectoscale (hundreds of FLOPs per second)
  • Goal for Computers in 2025 (Speed of the Race to Supercomputing): Exascale (quintillions of FLOPs per second)

Advances in supercomputing will continue to dominate the news with these two nations making the development of the fastest supercomputer a priority. As November approaches and the new TOP500 list is released, it will be very interesting to see where the rankings lie and what interconnects the respective architects will pick.

To InfiniBand and Beyond – Supercomputing Support for NASA Missions

June 11th, 2015


High performance computing has been integral to solving large-scale problems across many industries, including science, engineering and business. Some of the most interesting use cases have come out of NASA, where supercomputing is essential to conduct accurate simulations and models for a variety of missions.

NASA’s flagship supercomputer, Pleiades, is among the world’s most powerful, currently ranking seventh in the United States and eleventh globally. It is housed at the NASA Advanced Supercomputing (NAS) facility in California and supports the agency’s work in aeronautics, Earth and space science and the future of space travel. At the heart of the system is InfiniBand technology, including DDR, QDR and FDR adapters and cabling.

The incremental expansion of Pleiades’ computing performance has been fundamental to its lasting success. Typically, a computer cluster is fully built from the onset and rarely expanded or upgraded during its lifetime. Built in 2008, Pleiades initially consisted of 64 server racks achieving 393 teraflops with a maximum link speed of 20Gb/s. Today, the supercomputer boasts 160 racks with a theoretical peak performance of 5.35 petaflops, or 5,350 teraflops, and a maximum link speed of 56Gb/s.

To further demonstrate the power of the InfiniBand-based Pleiades supercomputer, here are several fun facts to consider:

  • Today’s Pleiades supercomputer delivers more than 25 million times the computational power of the first Cray X-MP supercomputer at the NAS facility in 1984.
  • The number of days it would take every person in the world to complete one minute of Pleiades’ calculations if they each performed one calculation per second, eight hours per day: 1,592.
  • The NAS facility has the largest InfiniBand network in the world, with over 65 miles (104.6 km) of cable interconnecting its supercomputing systems and storage devices-the same distance it would take to stretch to from the Earth’s surface to the part of the thermosphere where auroras are formed.

New InfiniBand Architecture Specification Open for Comments

October 15th, 2012

After an extensive review process, Release 1.3 of Volume 2 of the InfiniBand Architecture Specification has been approved by our Electro-Mechanical Working Group (EWG). The specification is undergoing final review by the full InfiniBand Trade Association (IBTA) membership and will be available for vendors at Plugfest 22, taking place October 15-26, 2012 at University of New Hampshire Interoperability Lab in Durham, New Hampshire.

All IBTA working groups and individual members have had several weeks to review and comment on the specification. We are encouraged by the feedback we’ve received and are looking forward to the official release at SC12, taking place November 10-16 in Salt Lake City, Utah.

Release 1.3 is a major overhaul of the InfiniBand Architecture Specification and features important new architectural elements:
• FDR and EDR signal specification methodologies
• Analog signal specifications for FDR, that have been verified through Plugfest compliance and interoperability measurements
• More efficient 64b/66 encoding method
• Forward Error Correction coding
• Improved specification of QSFP-4x and CXP-12x connectors, ports and management interfaces

The new specification also includes significant copy editing and organization to include sub volumes and improve overall readability. The previous specification, Release 1.2.1, was released in November 2007. As Chair of the EWG, I’m pleased with the technical progress made on the InfiniBand Architecture specification. More importantly, I’m excited about the impact that this new specification release will have for users and developers of InfiniBand technology.
