Developing low-latency, high-performance software for tiered storage systems running on commodity hardware, that can be used in a number of applications, including cloud systems. Involved in operational management, product direction, and the overall storage architecture of the system.

Build Key-value and MySQL appliances for use in internet data centers. Worked on product definition and strategic direction. Acquired by SanDisk in 2012.

Developed the world’s fastest low-latency, high-bandwidth InfiniBand system adapters. It was selected by the tri-labs (Lawrence Livermore National Laboratory, Sandia, and Los Alamos National Laboratory) in 2011 for use in their supercomputer clusters. PathScale was acquired by QLogic in 2006. The technology was later acquired by Intel in 2012 from QLogic for use in their new high-performance Omni-Path interconnects.

Managed a research group that designed and built a massively parallel custom hardware logic simulation system for simulating processors and digital systems.

Managed microprocessor development and architecture groups designing MIPs processor chips.

Managed a systems architecture group doing research into new technologies for mainframe products after Key Computer was acquired by Amdahl.

Designed one of the first superscalar computers using ECL gate arrays. Key Computer was acquired by Amdahl in 1989.

Managed groups in both engineering and product marketing areas. Worked closely with sales to close business. Valid was a pioneer in the computer aided engineering field (CAE). It commercialized the SCALD design system that was developed at Stanford University and Lawrence Livermore National Labs (LLNL) as part of my Ph.D. thesis. Valid went public (IPO) in 1983.

Technical Director and principal designer of the S-1 supercomputer, a joint effort between LLNL and Stanford University.
