California Digital & Lawrence Livermore 
                Deploy Fastest Linux Cluster 
                23 Teraflop Peak System Is World's Second Fastest 
                
              FREMONT, CA, MAY 13, 2004
              Linux cluster vendor California Digital, Quadrics, and Intel 
                today announced that they had successfully deployed the most powerful 
                Linux supercomputer ever built, a 4,096 Itanium2 processor based 
                Linux cluster code named "Thunder" at Lawrence 
                Livermore National Laboratory.
              The Thunder cluster delivers 19.94 teraflops of sustained 
                performance, making it the most powerful computer in North 
                America. Thunder also boasts the largest Itanium 2 processor deployment, 
                as well as the largest implementation of Quadrics' low-latency 
                QsNet^II interconnect technology. These technologies allow Thunder 
                to achieve record cluster efficiency of 86.9%, an important metric 
                in measuring cluster scalability.
              "We're proud to have successfully delivered such a ground-breaking 
                Linux cluster with world-record performance and efficiency," 
                reported California Digital CEO B.J.Arun. "Thunder sets important 
                benchmarks for massively-parallel Linux computing. "For years, 
                supercomputers have been a high-tech, exclusive domain for big 
                players with deep pockets. The lowest estimate of Japan's Earth 
                Simulator is $350 million. 
              "Our machine costs only $20 million," Arun said. "For 
                a small-size company like ours - we are just about 100 people 
                worldwide - for a company of our size to have done this, I can't 
                explain to you how thrilled all of us were." 
              He added that they were helped by their research staff in Bangalore. 
                "We've done it primarily by leveraging a lot of our engineering 
                in the US primarily in India," he said. "We've got a 
                subsidiary in Bangalore which provides a lot of the professional 
                skills that are very necessary to be able to produce such deployments." 
              
              His firm's CTO is Srinidhi Varadarajan, the brilliant computer 
                scientist who hit national headlines by building the world's third 
                fastest supercomputer by networking a cluster of Apple G5 servers. 
                Varadarajan's groundbreaking patented innovation is Déjà 
                vu, a software that helps avoid breakdowns. 
              "Déjà vu allows commodity structures that 
                we are building to be extremely reliable," Arun said. "One 
                of the last barriers between why somebody pays $300-400 million 
                on this mainframe machine versus what we built is this reliability 
                angle. And we have completely removed that last barrier." 
              
              Thunder uses 1,024 California Digital 6440 servers, each 
                with four Intel Itanium2 1.4GHz processors with 4MB of cache, 
                8GB of RAM, and 73GB of local storage. "Working with California 
                Digital and Lawrence Livermore has been a great opportunity to 
                demonstrate the absolute performance and scalability that can 
                be achieved with Intel's Itanium2 processor" said Intel Enterprise 
                Platforms General Manager Richard Dracott.
              Thunder's efficiency and scalability rest on the strength 
                of its sophisticated interconnect technology, Quadrics' QsNet^II 
                offering. QsNet^II (Elan4) provides the underlying high bandwidth 
                and low latency MPI communications required by today's demanding 
                scalable applications. With support for broadcast in hardware 
                and scaleable collective operations, QsNet^II scales clusters 
                efficiently to over 4,000 nodes.
              Despite the technical sophistication of Thunder and the incorporation 
                of new technologies, California Digital deployed Thunder in 
                five months, speeding delivery of computing solutions to support 
                Lawrence Livermore's national security and science programs in 
                fields such as materials science, structural mechanics, electromagnetics, 
                atmospheric science, seismology, biology, and inertial confinement 
                fusion. 
                "Thunder represents the next generation of Linux cluster 
                for scientific simulation," remarked Mark Seager, Livermore's 
                Assistant Department Head for Advanced Technology. "Our applications 
                are seeing a 50% to 400% speed up over our Xeon base clusters."
              Thunder uses a number of innovative open-source software 
                tools developed by California Digital and Lawrence Livermore to 
                manage the cluster effectively, leveraging the industry-leading 
                remote management capability of Intel's Itanium2 system family. 
                California Digital has
                released a number of these tools under open source licenses as 
                part of its freeIPMI project for server management and configuration.

              About California Digital
              California Digital is a privately held company 
                with worldwide headquarters in Fremont, California and Engineering 
                and Development Centers in Blacksburg, Virginia and Bangalore, 
                India. California Digital acquired the systems division of VA 
                Linux Systems (now VA Software) in late 2001 and re-launched VA's 
                server business thereafter. 
              California Digital focuses on providing massively-parallel 
                Linux or OS X compute clusters to enterprise technical computing 
                customers in various vertical markets such as manufacturing, oil 
                and gas exploration, bioinformatics, financial services, and digital 
                content creation. 
              California Digital provides turnkey cluster solutions, 
                including system and interconnect integration, software support 
                and configuration, application optimization and porting, performance 
                tuning, and comprehensive cluster manageement tools. 
              California Digital customers can reduce costs 
                by up to 90% by migrating compute-intensive applications away 
                from proprietary, "big iron" UNIX systems to massively 
                parallel Linux or OS X clusters. Toward this end, California Digital 
                offers turn-key clusters completely supported and configured to 
                run required applications upon delivery and commissioning. 
              California Digital personnel have deployed two 
                of the five most powerful supercomputers on Earth -- the 19.94 
                teraflop "Thunder" cluster at Lawrence Livermore National 
                Laboratory and the 10.28 teraflop System X at Virginia Tech. 
              California Digital specializes in 64-bit computing 
                solutions and deploying leading-edge technology to further the 
                adoption of massively-paralelle cluster computing.
