The transition to solid state non-volatile storage (NAND, 3D XPoint, etc.) is placing intense pressure on operating system and database system design and implementation due to both vastly increased performance and device behavior. Our group at Micron is working to define and implement new ways of using these hardware technologies to enable new levels of performance at the system level.

Ticom Geomatics develops and fields communications intelligence (COMINT) systems with a particular emphasis on precision geolocation of RF emitters. In addition to managing the other senior scientists I focused on communications and systems technologies with particular emphasis on global C2 and data sharing for an ISR grid across disadvantaged intermittent communication links.My architecture and development work was focused on globally distributed systems (hierarchical and P2P). In addition to enhancing TGI's legacy system, I designed and helped in developing their next-generation COMINT acquisition/prosecution system. That system was built using SOAP and REST web services, JEE server-side technologies, and HTML5/CSS/JavaScript thin clients (Flash for audio). The draft JSON schema mechanism was used to ensure that testable, defined interfaces were present at all levels of the application stack.My prototyping work at TGI was focused in two areas: (1) system-level performance of complex signal processing tasks, particularly in P2P mesh networks, and (2) automated synthesis of user/group semantic contexts using static/dynamic geospatial data and a domain-specific knowledge-base.

Integral Wave was an analog mixed-signal semiconductor startup building single-die, multi-output DC-DC power converters (die + discretes as a SiP) with rich digital control. I was responsible for the customer's experience with the product, including managing the FAE team, guiding non-SiP hardware development (prototyping boards and programming hardware), and design/characterization software tools. The primary software tool allowed virtually anyone to design and configure a power system, inclusive of physically modeling the design for thermal and electrical safety. That tool also allowed live monitoring (and control) of any number of the power converters, with real-time monitoring of voltage, current, temperature, and warning/fault conditions. All software was cross-platform (Windows & Linux), achieved through the use of Java (Swing) and a FTDI USB-to-I2C bridge.

Crossroads Systems is a provider of networked storage solutions. During my tenure with Crossroads I built the team and technology for their StrongBox database security solution. The system functioned as an in-line IPS at the database network protocol layer with business rules about allowed/disallowed behaviors. The solution parsed database traffic at the network wire-level and fed the transactions to a high-performance constraint processing engine to enforce business-level security policies (users, network locations, times of day, tables/views, etc.). The security engine could support several thousand queries per second being checked against hundreds of rules covering tens of thousands of business elements. The query snooping and security engine were implemented in C++, with the remainder of the application implemented in Java and Web UI technologies.

Newisys developed enterprise-class server designs (AMD64) that were sold through tier-1 OEMs, including multi-chassis systems. My teams were responsible for the systems management capabilities (hardware and software) and relations with Microsoft and the Linux community to support the move to 64-bit OS technology.The systems management technology included full lights-out management with no KVM (from a bare-metal state), remote scripting of systems management that evolved into the DMTF SMSH standard, and the non-host hardware/firmware to allow multi-chassis systems to boot and run unmodified copies of Windows and Linux. Non-host functions were implemented in C++ on embedded Linux (PowerPC SOC) and were accessible via a Web UI.

Net Perceptions built analysis tools for on-line and off-line retailers, including recommendations, campaign planning and performance assessment, association rule mining and clustering. My teams were responsible for development of all of the server-side analytic technologies. Data sizes were in the terabyte+ range, requiring the use of scale-out parallel data flow techniques and incremental machine-learning. Analytics were built in C++ and Java, with a scripting language to manifest and control the data flow networks.

Convex (acquired by HP in 1996) built CC-NUMA servers based on HP PA-RISC processors. I worked on the OS internals team where I led efforts to improve OS performance and scaling.
