Intel's QuickPath Interconnect could be a performance breakthrough for supercomputers.
Intel has struck a new agreement with Cray
that the two companies say they hope will lead to technological breakthroughs
in the field of supercomputers and high-performance computing.
Intel and Cray announced what they called a "multiyear" agreement
on April 28. While Intel will supply x86 microprocessors to Cray, the two
companies also hope to develop new system and chip technologies that will push
the HPC envelope in the future.
Cray CEO and President Peter Ungaro told
eWEEK that he expects the first of these jointly developed HPC
systems to hit the commercial market in either 2011 or 2012, when his company
moves closer toward developing its "Cascade" project, which aims to create
a single adaptive system that will allow one machine to handle different HPC
"It's really about us and Intel partnering on an R&D level to build
future systems that will really make a big change within the overall
industry," Ungaro said. "As I like to say, this will blur the lines
between where typically the processor vendor and the system vendor kind of
start and stop."

The agreement with Intel also gives Cray access to another processor
vendor. For years, Cray only used x86 chips from Advanced Micro Devices. When AMD
introduced the first Opteron processor, Cray used those chips to create its Red
Although Intel trailed AMD when it came
to incorporating into its silicon the type of technology that HPC
vendors wanted, Intel has made significant strides to overcome that gap.
New chip connections, new breakthroughs
the new Nehalem microarchitecture due out later in 2008,
Kirk Skaugen, vice
president of Intel's Digital Enterprise Group, said Cray and other vendors can
take advantage of new technologies such as an integrated memory controller and
what Intel called the "QuickPath Interconnect," which replaces the
front side bus and creates a high-speed, low-latency way to connect chips
When it incorporates the QuickPath Interconnect into its own systems, Cray
will be able to connect its vector processors, which allow for high-memory
bandwidth, to Intel's standard x86 processors, which should increase the
overall performance of these supercomputers.
The two companies are also looking for new ways to develop software that
will take advantage of the different types of processors that Cray will
incorporate into these new supercomputers.
The result, Skaugen said, is supercomputers that should easily pass a
petaflop in performance-1 quadrillion calculations per second-to deliver an
exaflop, which is 1,000 times greater than a petaflop.
Steve Conway, an analyst with IDC, said both
Cray and Intel will benefit from this new relationship. For Cray, the agreement
gains it access to another chip vendor to help it fill orders and expand its
reach within the high end of the HPC market.
For Intel, it's a chance to delve further into a market that should grow
significantly in the next few years.
Interest in HPC goes
IDC is predicting that the HPC
market will grow from $11.6 billion in 2007 to more than $16 billion by 2012.
One reason for the increased interest in these machines is that many
enterprises and other commercial businesses are beginning to invest in HPC
in order to access even greater computing power.
"At the high end of the market, Cray is a company that is pushing this
type of technology very hard and Intel wants to put more emphasis on
high-performance computing and pay more attention to HPC
user requirements," Conway
