Cray Shasta Vulcan Supports U.K.'s
November 6, 2019
United Kingdom’s Atomic Weapons Establishment (AWE) has selected the
Cray Shastaä supercomputer to support security and defence of the U.K.
The Shasta system, purpose-built for the exascale era, was chosen due to
its ability to run mixed workloads and applications at the best total
cost of ownership (TCO) for a system across five years.
AWE’s supercomputer, named Vulcan, will feature a single Shasta
supercomputer with expected performance of more than 7 petaflops. Shasta
will play an integral role in maintaining the U.K.’s nuclear deterrent.
“High-performance computing is a critical aspect of AWE,” said Andy
Herdman, head of HPC at AWE. “It underpins the vast majority of our
science-based programs, and we’re continually looking for ways to
enhance and support this important work. This is why we chose Shasta,
for its unique and powerful features, as well as its ability to provide
The U.K. Ministry of Defence is responsible for the program and
stewardship of AWE, which is operated under contract by AWE Management
Limited. The Establishment has been at the forefront of U.K. nuclear
deterrence for more than 60 years. Predicated on the Comprehensive
Nuclear Test Ban Treaty which prohibits emission of nuclear yield, AWE
must continually verify the safety and reliability of nuclear warheads
through science-based and computational programming. Shasta will further
extend AWE’s sophisticated scientific and technological capabilities.
are incredibly proud to be chosen by AWE to support their important
mission,” said Peter Ungaro, president and CEO at Cray. “Shasta will
bring Exascale Era technologies to bear on AWE’s challenging modeling
and simulation data-intensive workload and enable the convergence of AI
and analytics into this same workload, on a single system.”
Vulcan’s Shasta architecture will include the Cray Slingshot™
interconnect, AMD EPYCä 7542 processors and Cray ClusterStor® Lustre
storage. The high performance storage system will offer nearly 100
gigabytes per second of I/O performance.
“We are pleased to once again partner with Cray to deliver a powerful
new supercomputer that will support critical research efforts in the
U.K.,” said Forrest Norrod, senior vice president and general manager,
AMD Datacenter and Embedded Systems Group. “Our 2nd Generation AMD EPYC™
processors provide unprecedented performance while helping to reduce
TCO, key elements for driving success for AWE in the coming years.”
