Features
· Single Port Cluster Administration and Management ·Cluster Filesystem · Cluster-Wide Job Scheduling · High Performance Communication Libraries

SGI Advanced Cluster Environment (ACE) for IRIX provides the industry's leading compute cluster environment. SGI ACE for IRIX is a fully integrated cluster package fro compute-intensive environments, scaling the SGI 2100 server from 8 to 64 processors. In a complete cluster atmosphere, ACE is a comprehensive software package used to build the following types of clusters: · Capability clusters address huge problems, which need to scale to multiple CPUs; it is more efficient and economical to solve some of these problems in a cluster environment than on a large single system · Throughput clusters run multiple jobs (either different applications or multiple instances of the same application) in a batch-style environment Providing an Alternative: Cutting-Edge Cluster Environment with Low Total Cost of Ownership ACE for IRIX is the result of years of development of high-performance computing tools. The same tools used in managing systems like the 6,144-processor SGI cluster at Los Alamos National Labs are now available in an integrated, easy-to-use package. Advanced tools are provided to ease cluster administration, providing a single point of administration and single system view to the end user. Many user applications run as efficiently in a a clustered environment as in a single-system environment. Highperformance interconnect hardware and software and an advanced message passing library ensure maximum performance for the most challenging cluster jobs. in addition, clusters allow for greater application availability than a single system. ACE for IRIX has gone through intensive testing in SGI's cluster engineering labs to ensure the interoperability and functionality of the whole package. Best-of-breed cluster software has been assembled from SGI developed software to create a robust clustering environment to address your toughest problems. SGI ACE for IRIX is backed by SGI's industry-leading service and support organization. SGI offers full support for this comprehensive cluster solution. An extremely economical managed service gets your cluster up and running and trains your staff on the components of the overall solution. Components of SGI ACE for IRIX ACE consists of a number of tools to support a single-system view over a cluster of systems. In the management arena there are tools to provide integrated console support, monitoring, and software distribution. ACE provides a high-performance clustered filesystem. In addition, tools to support job scheduling and programming across the cluster are available.

Management IRISconsole is an intelligent, easy to use central control point that manages and monitors servers and logs their activity. Performance Co-Pilot is designed for the in-depth analysis and mechanisms that are needed to understand and manage the hardest performance problems in our most complex systems. It provides a cluster-wide performance view from a single console. This helps in quick identification and elimination of bottlenecks in the cluster. RoboInst is a soft ware distr ibution product designed to help automate the process of installing operating system upgrades, operating system and application patches, and applications for a distributed network of SGI systems. It can perform in-place upgrades of software without manual deinstallation of previous versions. RoboInst automates tasks at the IRIX miniroot level that include the ability to repartition the disk, create filesystems, install software, and execute any other shell scripts that are provided.

File CXFS is a highly scalable and resilient clustered filesystem that enables unprecedented data access across shared disks in a clustered configuration. It runs on storage area network (SAN) disks, such as Fibre Channel, in a cluster environment. Performance Message Passing Toolkit (MPT) provides optimized implementation of the industry's top messagepassing librar ies together as one product. MPT permits application developers to use standard, portable interfaces for developing applications while obtaining the best communication performances. Scheduling Platform Computing Corporation's Load Sharing Facility (LSF) gives effective workload distribution and job scheduling across the cluster. It also maximizes the use of applications and system resources critical to achieving enterprise business objectives.
