The Data Stack

Today the Texas  Advanced Computing Center (TACC), together with The University of Texas at  Austin, announced that they will deploy a 10 Petaflop HPC  Linux cluster called “Stampede.” When it is operational at the beginning of  2013, “Stampede” is expected to be among the most powerful computers in the  world. Normally, we’d celebrate this important design, but for all of the Intel  employees working on Intel® MIC Architecture for the past several years, this  announcement has a very special meaning.

 

For Intel this is an  exceptional announcement as those 10 Petaflops will be delivered entirely by Intel  technology. “Stampede” will be based on future 8-core Intel® Xeon® processors  E5 family (formerly known as Sandy Bridge-EP) that will deliver 2 petaflops of performance. But this is  also the first announcement of a  system that will include thousands of Intel® Many Integrated Core (Intel® MIC) architecture co-processors  codenamed “Knights Corner.”, which will provide additional 8 Petaflops.  In all,  “Stampede’s” 10 petaflops performance will be achieved thanks to hundreds of  thousands of Intel Xeon and Intel MIC cores – all based on Intel  architecture.

 

These forthcoming Intel®  Xeon processors E5 family, which are aimed at numerous market segments ranging  from enterprise data centers, to cloud computing applications, to workstations  and small businesses, are shipping to customers for revenue now. Intel is experiencing  approximately 20x bigger demand for initial production units and 2x  more design wins for this processors compared to the launch of the Intel® Xeon®  processor 5500 series in 2009. We expect many high performance computing (HPC)  and cloud customers to deploy their systems this year based on these new Intel Xeon  processors with broad systems availability in early 2012.

 

“Knights Corner,” a  co-processor aimed at highly parallel workloads, will be the first commercially  available product featuring the Intel MIC architecture. “Knights Corner” is an  innovative design that includes more than 50 cores and will be built using Intel’s  leading edge 22nm 3D Tri-Gate transistor technology when in production.

 

It’s very important to  understand why TACC choose to include Intel MIC architecture in Stampede.  Since Intel MIC was announced more than a year ago at the International  Supercomputer Conference (ISC) in Hamburg, more than 100 Intel MIC partners  have been evaluating its potential. Earlier this year TACC joined other universities and  research organizations around the world to build applications that take full  advantage of the Intel MIC architecture. At this year’s ISC show in Hamburg,  many of those MIC partners including Forschungszentrum Juelich, Leibniz  Supercomputing Centre (LRZ), CERN and Korea Institute of Science and Technology  Information (KISTI) shared their results,  including how they were  able to take  advantage of the Intel MIC co-processor’s   parallel processing capabilities while  using well known IA instruction set. Using these widely available programming  tools can help save time and money as it negates the need to learn any proprietary  languages.

 

We believe the decision to build “Stampede”  based on Intel Xeon processors E5 family and Intel MIC architecture based “Knights  Corner” is a recognition of the advantages  that standardized, high-level CPU programming  models bring to developers of highly-parallel computing workloads.  Being  able to run the same code on both Intel Xeon processors and “Knights Corner” co-processors  should allow developers to reuse their existing code and programming expertise  which leads to greater productivity. Also, since Knights Corner is based on  fully programmable Intel processors, it can run complex codes that are very  difficult to program on more restrictive accelerator technologies.

 

TACC  also announced that the current system is  only the beginning as they plan to expand ”Stampede” in the future and increase  the total system performance by more than 50 percent to 15 petaflops with the  help of future generations of Intel products.

 

What does all of this  mean for the future of HPC? Last week at the Intel Developer Forum, Kirk  Skaugen, VP and GM of Intel’s Data Center and Connected Systems Group, talked  about the huge growth that is expected in HPC in coming years. (For those who  didn’t have a chance to attend IDF you can see video of Kirk’s presentation  here -> part 1 & part 2).  Our estimations show that by 2015, the world’s top 100 supercomputers  will be powered by 2 million CPUs and by 2019 this number will reach 8 million  CPUs. To give you a perspective, in 2010, Intel shipped about 8 million server  processors in total.

 

This growth is fueled  by the constant need for performance to solve some of the world’s biggest  problems. Here’s one example: In 1997 the cost of sequencing a human genome was  about a million dollars – mostly due to the scarcity of sufficient computing  power. In 2009, the cost had dropped to $10,000. Due to continuing increases in  compute performance, we believe that in a year or two the price can drop to $1,000.  This relatively low cost might enable a patient to have his individual genome  analyzed and an assessment made of his likelihood of contracting diseases. From  there, preventative measures and treatments could be customized precisely for  this one person. One of the keys to this “personalized medicine” is providing sufficient  processing power to make the necessary calculations in as little time – and as  cheaply – as possible.

 

Intel and HPC are a  great match. Today, Intel processors power nearly 80 percent of the Top500 list of super-computers  – which is great for our business.  Overall,  Technical Computing including HPC makes up about 30% of our data center  business today. In response to the needs of technical computing developers and  customers, Intel is committed to providing new technologies that will deliver even  more performance to scientists to help fuel the next generation of scientific  discovery. Again for those who were not at IDF, I recommend viewing a great video of a speech given by John Hengeveld, Director  of HPC strategy at Intel. John discusses the future of supercomputing and why  it’s critical to enable broader access to huge amounts of processing power.

 

This announcement of  the first ever supercomputer combining the   benefits of microprocessor and co-processors - without sacrificing the  programming compatibility - is another step towards making access to HPC  resources easier, more cost-effective, and more time-effective. This allows our  scientists to focus on their own field of science and not the computer science.
