Cray® XE6™ Supercomputer

Cray built the world's first production petaflops system with the Cray® XT5™ supercomputer. With the Cray® XE6™ system, Cray raised the expectations for high performance computing once again.

The Cray XE6 supercomputer takes the proven Cray XT5 infrastructure and combines it with two innovative technologies: AMD’s powerful multicore processors and the award-winning Gemini interconnect. The result is a system that brings production petascale to a wider HPC community and fundamentally changes how Cray systems communicate. Designed to scale to over 1 million processor cores, every aspect of the Cray XE6 supercomputer — from its industry-leading resiliency features to its host of scalability-boosting technologies — has been engineered to meet science’s ever-toughening demands for scalability, reliability and flexibility.

Cray® XE™ Series Supercomputers: Scalable Performance

Gemini Scalable Interconnect

The Gemini interconnect is the heart of the Cray® XE6™ system. Capable of tens of millions of MPI messages per second, the Gemini ASIC is designed to complement current and future massively multicore processors.

Scalable Programming Paradigms

In addition to supporting MPI over the standard programming languages of C, C++ and Fortran, the Gemini interconnect has direct hardware support for partitioned global address space programming models including Unified Parallel C (UPC), Co-array Fortran and Chapel. Gemini allows remote references to be pipelined in these programming models which can result in orders-of-magnitude performance improvement over library-based message passing models. 

Scalable Software

The Cray XE6 system ships with the Cray Linux® Environment (CLE), a suite of high performance software including a SUSE Linux-based operating system designed to run large, complex applications and scale to more than 1 million processor cores. 

Scalable Compute Nodes

Each Cray XE6 blade includes four compute nodes for high scalability in a small footprint — up to 96 processor cores per blade or 2,304 processor cores per cabinet. Each compute node has two AMD Opteron™ 6300 series processors (16 core) coupled with its own memory and Gemini communication interface. 

Scalable I/O

The Cray XE6 I/O subsystem scales to meet the bandwidth needs of even the most data-intensive applications. The newly designed Cray XIO service blades provide four I/O nodes, each with a six-core AMD Opteron series 2000 processor coupled to 16 GB of DDR2 memory and a PCI-express GEN2 interface.

Production Reliability

Integrated Hardware Supervisory System

Cray’s Hardware Supervisory System (HSS) integrates hardware and software components to provide system monitoring, fault identification and recovery. An independent system with its own control processors and supervisory network, the HSS monitors and manages all major hardware and software components in the Cray XE6 supercomputer.

Cray XE6 System Resiliency Features

The Gemini interconnect is designed for large systems in which failures are to be expected and applications must run to successful completion in the presence of errors. Gemini uses error correcting code (ECC) to protect major memories and data paths within the device. 

Adaptive Supercomputing

Extreme Scale and Cluster Compatibility in One System

The Cray XE6 system provides complete workload flexibility. For the first time, users can buy a single machine to run both a highly scalable custom workload and industry-standard ISV workload.

Support for Other File System and Data Management Services

Customers can select the Lustre® parallel file system or another option including connecting to an existing parallel file system. The Cray Data Virtualization Service allows for the projection of various other file systems (including NFS, GPFS™, Panasas® and StorNext®) to the compute and login nodes on the Cray XE6 supercomputer.

Cray Efficiency with ECOphlex™ Cooling

With a standard air- or liquid-cooled high-efficiency cabinet and optional ECOphlex™ technology, the Cray XE6 system can reduce cooling costs and increase flexibility in datacenter design.

Software for Cray® XE6™ and Cray® XE6m™ Systems

 Cray® XE6™ systems utilize the Cray Linux® Environment (CLE). CLE is a suite of high performance software that includes a Linux-based operating system designed to run large, complex applications and scale efficiently to more than 500,000 processor cores. The Linux environment features a compute kernel that can be configured to match different workloads. When running highly scalable custom applications, the compute nodes can be run in a lightweight mode, ensuring that operating system services do not interfere with application scalability. This special design ensures virtually nothing stands between the user's scalable application and the hardware.

With CLE many ISV applications are available "out of the box" under Cluster Compatibility Mode (CCM). In addition, selected ISV applications are highly tuned and available under Extreme Scalability Mode (ESM).

Programming Environment

The CLE programming environment includes tools designed to complement each other, resulting in a rich, easy-to-use programming environment that facilitates the development of scalable applications.

  • Parallel programming models: MPI, Cray SHMEM, UPC, OpenMP and Co-Array Fortran within the node
  • MPI 2.0 standard, optimized to take advantage of the scalable interconnect in the Cray XE system
  • Various MPI libraries supported under Cluster Compatibility Mode
  • Support for the ISO Fortran standard (2008) including parallel programming using coarrays, C/C++ and UPC
  • High-performance optimized math libraries of BLAS, FFTs, LAPACK, ScaLAPACK, SuperLU and Cray Scientific Libraries
  • Cray Performance Tool Suite with CrayPAT™ and Cray Apprentice2™
