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 12.25 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.

Executive Team

B.J. Arun brings over 20 years of leadership experience in the Enterprise Technical Computing industry. Arun co-founded California Digital in San Jose, CA in 1994 and has run the company profitably ever since. He set up India's first Linux only company when he set up California Digital (India) Private limited as a wholly owned subsidiary in 1999.

Arun orchestrated the acquisition of the assets of VA Linux Systems (Nasdaq: LNUX) in 2001 which catapulted California Digital into a market leadership position in the space of Linux based High Performance Computing and related software services.

Prior to California Digital, Arun served in Product Marketing for Micronics Computers (Nasdaq: MCRN), a leader in the design and manufacture of high end X86 based motherboards. He was responsible for defining the technology road map for the company's industry leading designs of server and desktop products.

Arun is a charter member of TiE, The Indus Entrepreneurs, a not-for-profit global network of entrepreneurs and professionals dedicated to the advancement of entrepreneurship.

Arun holds a Bachelors degree in Computer Science from the Bangalore University (India).

Srinidhi Varadarajan received his Ph.D. in Computer Science from the State University of New York, Stony Brook in 2000. He presently serves as the Director of the Terascale Computing Facility at Virginia Tech and as an Assistant Professor in the Department of Computer Science. Dr. Varadarajan is the recipient of a CAREER award from the National Science Foundation, the Egg Factory Technology Innovation award and a Faculty Fellow award from the College of Engineering, Virginia Tech.

Dr. Varadarajan's research is focused on transparent fault tolerance for massively parallel supercomputers, scalable network emulation, compiler directed strategies for flexible data sharing models and routing algorithms for backbone IP networks. In the area of transparent fault tolerance his work concentrates on developing incremental checkpointing, recovery and migration algorithms. His research in network emulation is focused on building a distributed system that can scale to emulate hundreds of thousands of virtual nodes. This work involves research on several areas, including compiler directed mechanisms for transparent generation of reentrant code from non-reentrant sources, automatic checkpointing and recovery, code migration, dynamic load balancing and 3D environments for network traffic visualization. In the area of routing algorithms, he is exploring the use of AI techniques such as reinforced learning for use in a probabilistic framework for multi-path routing protocols.

Dr. Varadarajan is the architect of System X, the third fastest supercomputer in the world located at the Terascale Computing Facility at Virginia Tech.
