INSTRUMENTAL ANNOUNCES AVAILABILITY OF PERFSTAT 2.0, THE INDUSTRY'S MOST POWERFUL UNIX PERFORMANCE MONITORING SOFTWARE

 MINNEAPOLIS, Sept. 28 /PRNewswire/ -- Instrumental Inc. today announced the availability of a powerful new version of its PerfStat(TM) UNIX(R) performance monitoring software for Cray Research, Inc., systems. PerfStat 2.0 is the only UNIX performance monitor able to collect any specified performance data in a running system, including data generated by user applications. One of PerfStat 2.0's breakthroughs is its extreme efficiency.
 Dr. Elaine Frankowski, vice president of development said, "Performance monitors typically consume between 1 percent and 5 percent of the monitored system's cpu capacity. In most cases PerfStat 2.0 consumes only 0.01 percent to 0.1 percent of the cpu capacity, while gathering substantially more data than typical monitors."
 PerfStat 2.0 will be available next month for Convex Computer Corp. systems and the development of an SGI version is under way. This demonstrates that PerfStat's unique, self-configuring data-collector architecture, which requires no changes in the monitored system, is easily ported to new platforms.
 Rene Copeland, president and CEO said, "This is an important milestone toward Instrumental's goal of providing tools for managing the performance of the entire computing environment. We believe, and our customers' plans bear out, that the data centers of the future require tools which can integrate performance data from all systems and network hardware. This will provide a coherent view of the computing environment's performance, enabling network-wide performance management and capacity planning."
 General Motors is using PerfStat to improve throughput of its CRAY Y- MP system. Instrumental has also recently been selected to provide PerfStat 2.0 for three major U.S. Government supercomputer sites. They join NASA's Johnson Space Center, Dupont, the Minnesota Supercomputer Center, the San Diego Supercomputer Center, the National Center for Atmospheric Research, and Cray Research, Inc. in reaping benefits from using PerfStat. Copeland said, "I am gratified that the first automotive company to adopt supercomputing is also the first to adopt PerfStat. I am also pleased that these key government supercomputer centers have selected PerfStat."
 The feedback from PerfStat 2.0 users indicates that they have created the industry's most powerful performance monitor. Cray Research's Software Division and their Corporate Computing and Networking Division have begun to use PerfStat 2.0 on many of the in- house systems. According to Rebecca Koskela, manager of system performance & analysis at Cray Research, "PerfStat provides us with a unique, productive and efficient means for evaluating the performance of our systems during the software development cycle. We particularly like the ability to choose the specific performance parameters that we want to monitor."
 PerfStat, based on the emerging standard for performance management from the Unix International Performance Management Work Group (PMWG), uses a client-server architecture to collect, interpret and graph real- time and historical system, application and process-level data. PerfStat, acting as an "instrument panel" for managing UNIX computer systems and networks, enables data center staff to monitor and tune the overall workload, quickly isolate problems, reduce turn around time for critical jobs, and improve their productivity, and the productivity of end users.
 Instrumental Inc., located in Minneapolis, creates, markets and supports graphics-oriented, client-server productivity tools for UNIX computer systems and their associated networks. In addition to software tools, Instrumental offers training and consulting services, including system tuning, capacity planning and benchmark design and evaluation.
