Cray DVS: Data Virtualization Service
Cray DVS: Data Virtualization Service Stephen Sugiyama and David Wallace, Cray Inc. ABSTRACT: Cray DVS, the Cray Data Virtualization Service, is a new capability being added to the XT software environment with the Unicos/lc 2.1 release. DVS is a configurable service that provides compute-node access to a variety of file systems across the Cray high-speed network. The flexibility of DVS makes it a useful solution for many common situations at XT sites, such as providing I/O to compute nodes from NFS file systems. A limited set of use cases will be supported in the initial release but additional features will be added in the future. KEYWORDS: DVS, file systems, network protocol used in the communication layer takes advantage 1. Introduction of the high-performance network. The Cray Data Virtualization Service (Cray DVS) is Most file systems are not capable of supporting a network service that provides compute nodes hundreds or thousands or tens of thousands file system transparent access to file systems mounted on service clients. With DVS, there may be thousands of clients that nodes. DVS projects file systems mounted on service connect to a small number of DVS servers; the underlying nodes to the compute nodes: the remote file system file system sees only the aggregated requests from the appears to be local to applications running on the DVS servers. compute nodes. This solves several common problems: • Access to multiple file systems in the data center 2. Architecture • Resource overhead of file system clients on the The Cray XT series of supercomputers contain compute nodes compute nodes and service nodes.

The Cray XT4 and Seastar 3-D Torus Interconnect
The Cray XT4 and Seastar 3-D Torus Interconnect April 6, 2010 BYLINE Dennis Abts [email protected] Google Inc. Madison, WI USA [email protected] SYNONYMS Cray Red Storm, Cray XT3, Cray XT4, Cray XT5, Cray XT, Interconnection Networks DEFINITION The Cray XT4 system is a distributed memory multiprocessor combining an aggressive superscalar proces- sor (AMD64) with a bandwidth-rich 3-D torus interconnection network that scales up to 32K processing nodes. This chapter provides an overview of the Cray XT4 system architecture and a detailed discussion of its interconnection network. DISCUSSION The physical sciences are increasingly turning toward computational techniques as an alternative to the traditional “wet lab” or destructive testing environments for experimentation. In particular, computational sciences can be used to scale far beyond that of traditional experimental methodologies; opening the door to large-scale climatology and molecular dynamics, for example, which encompass enough detail to ac- curately model the dominant terms that characterize the physical phenomena being studied [2]. These large-scale applications require careful orchestration among cooperating processors to ply these computa- tional techniques effectively. The genesis of the Cray XT4 system was the collaborative design and deployment of the Sandia “Red Storm” computer which provided the computational power necessary to assure safeguards under the nu- clear Stockpile Stewardship Program which seeks to maintain and verify a nuclear weapons arsenal with- out the use of testing. It was later renamed the Cray XT3 and sold commercially in conﬁgurations varying from hundreds of processors, to 10s of thousands of processors. An improved processor, faster processor- network interface, along with further optimizations to the software stack and migrating to a lightweight Linux kernel prompted the introduction of the Cray XT4; however, the underlying system architecture and interconnection network remained unchanged.
