Multiple vulnerabilities have been identified in SGI Advanced Linux Environment, which could be exploited by attackers to bypass security restrictions, cause a denial of service or execute arbitrary code. These issues are caused by errors in httpd, perl-Net-DNS and seamonkey. For additional information, see : FrSIRT/ADV-2007-2357 – FrSIRT/ADV-2007-2516 – FrSIRT/ADV-2007-2580

SGI Altix 4700 with 4TB Memory To Power NAS Technology Refresh Program

SUNNYVALE, Calif., July 23 /PRNewswire-FirstCall/ — SGI (NASDAQ: SGIC) and NASA today announced that the agency has selected a record-setting SGI(R) Altix(R) supercomputer in its evaluation of next-generation technology to meet future high-performance computing (HPC) requirements. The system was acquired as part of NAS Technology Refresh (NTR), a four-phase procurement process that eventually will replace the Columbia supercomputer system, powered by SGI Altix.
NASA’s new SGI Altix system is expected to be installed in August at the NASA Advanced Supercomputing (NAS) facility at the Ames Research Center at Moffett Field, Calif. The new system will be the first supercomputer to operate 2,048 processor cores and 4TB of memory under a single copy of Linux(R) — creating the largest Linux single system image (SSI) in the world. A larger SSI can accelerate scientific research by making all of the system’s processors and memory available to solve a single problem, or several problems at once.
Driven by 1,024 Dual-Core Intel(R) Itanium(R) 2 processors, the new system will generate 13.1 TFLOPs of compute power. The system’s dual-core processors allow more computing power per square foot, enabling NASA to pack more computing power into its supercomputing center. NASA also acquired an ultra-dense 240TB SGI(R) InfiniteStorage 10000 system to efficiently handle the massive data storage requirements.

EDMONTON, Alberta, July 23 — Obsidian Research Corporation, the leader in InfiniBand range extension, today announced that its Longbow Campus products have enabled NASA to relocate 15 percent (1,536 processors) of its high-ranking SGI Altix-based Columbia Supercomputer to another facility and seamlessly connect both locations without any performance degradation. This move allows NASA to free up additional building space in its compute center, to reduce the power and cooling requirements on any single location, and to create multi-site supercomputer clusters that now can scale, perform, and be managed as if they resided in one physical location since the Obsidian Longbow solutions add only 840ns of latency beyond the optical flight time between the two locations. By deploying eight, Longbow Campus products at each end, NASA transparently extends its InfiniBand fabric 3km, provides 8 GB/sec of bandwidth between the two locations, and only adds an additional 2RU worth of equipment that consumes a negligible 150W.
