Sun HPC ClusterTools 3.1 software released

Palo Alto 07 Mar 00 Sun Microsystems released Sun HPC ClusterTools 3.1 software, the latest version of its integrated package of development tools that connect multiple shared-memory machines for supercomputing-class performance. The new high performance computing (HPC) software provides extended functionality over version 3.0 and compatibility with Solaris 8, as well as Solaris 2.6 and 7 Operating Environments. The universities of Utrecht, The Netherlands, and Leipzig, Germany, are among the ClusterTool users.

Sun HPC ClusterTools 3.1 software includes enhanced debugging capabilities for the Message Passing Interface (MPI), an industry standard for parallel application development. Programmers can now use Prism software, a graphical programming environment, to debug serial programs, parallel MPI programs, or multi-threaded MPI programs. This makes it easier to develop highly scalable parallel applications, as well as support existing applications on Sun systems. In addition, users receive support for on-node, one-sided communications in MPI, an important feature in the MPI-2 standard. Sun HPC ClusterTools 3.1 software also includes Kerberos 5 for strong user- or server-level authentication, integrity and privacy.

"Sun HPC ClusterTools software is continuing to bring users additional features and functionality for complex workload management and optimization," said Steve Campbell, director of marketing for Sun's Data Center and High Performance Computing Group. "Our unique innovation is leading the way in high-end technical computing markets once again."

Along with performance enhancements, users receive a completely integrated suite of tools for performance analysis, tuning of their MPI applications, and managing a workload of highly resource-intensive parallel applications on Sun systems. These tools include: - Sun Cluster RunTime Environment (CRE) program - Prism graphical programming environment - Sun MPI program - Sun MPI I/O program - Sun Parallel File System (PFS) program - Prism graphical programming environment - Sun Scientific Subroutine Library (S3L) - Cluster Console Manager (CCM) - Switch Management Agent (SMA)

Users Show Commitment to Sun's Parallel Development Tools Sun is already experiencing rapid adoption of this new version of the Sun HPC ClusterTools software, for traditional supercomputing solutions and commercial applications. Some of the institutions currently taking advantage of the new software are the Universitat Leipzig in Germany and Utrecht University in The Netherlands.

"The new Sun HPC ClusterTools software provides us with the most complete integrated parallel development environment," said Dr. Yehudi Levine of the Debye Institute at Utrecht University in The Netherlands. "The Prism tools are a great boon for debugging complex programs and the MPI routines have simplified the task of writing parallel codes."

"Sun's HPC ClusterTools make it easy to manage resource-intensive applications, and they deliver an end-to-end environment for parallel distributed applications," said Robert Reilein of the Universitat Leipzig in Germany.
