Worked with processor design team to dramatically increase SPARC floating-point (FP) performance for analytics algorithms and BLAS3, 2, 1 routines. Optimizing dataflow, registers, FP unit design.Prepare and publish results of industry standard benchmarks on Oracle hardware and software.Editor of groups publications, both internal to Oracle and an external blog. Ensure performance of new systems, including low-level hardware and software investigations Diagnose customer problems and provide timely solutions. Provide support to sales staff in their preparation of proposed customer solutions. Integrated optimized math performance library (libsunperf) into R, numpy and netlib-java (used by Spark) for SPARC/Solaris systems. Worked with Oracle Advanced Analytics team and Oracle Graph Analytics team to improve performance. Oracle's representative to the SPEC HPG group. Tested SPEC benchmarks on shared memory parallel systems, distributed memory (clusters) systems, and GPU accelerated systems. Hardware included SPARC (up to 4096 threads) systems, 2-way to 8-way x86 systems, GPU workstation, clusters, AWS.Early user and evaluator of prototype hardware and software. Provided optimizations/requirements for future hardware design.

Oracle and Sun representative to SPEC HPG. Participated in the creation of distributed memory benchmarks (SPEC MPI2007 - MPI, Sparse Solvers, Molecular Dynamics ...), shared memory benchmarks (SPEC OMP2012 - OpenMP, Weather Modeling, CFD, QCD, ...) and accelerator benchmarks (SPEC Accel - OpenCL, OpenACC, OpenMP, CFD, Weather Modeling, Seismic, ... ). Duties involved attending meetings and exercising my company's vote.SPEC HPG Release Manager, in charge of packing benchmarks for testing and final release. Position is an officer of the group. Ran meetings when others were not available.

Performance benchmarks including SPEComp2012, SPEC CPU2006, Linpack, Stream, SPECweb2005, SPEC CPU2000. Published results, used analysis of benchmarks to improve future software and hardware. Investigate performance issues including scaling of benchmarks up to 144 threads, optimization of hot spots, diagnose customer problems and provide timely solutions. Provide support to sales staff in their preparation of proposed customer solutions. Sun's representative to the SPEC HPG group.Optimization of wide range of applications, including benchmark programs, customer applications or kernels, performance libraries. HPC applications/benchmarks include CFD, weather/climate, finance, structural analysis, bioinformatics, computational chemistry. Hardware included a variety of systems including 8-way to 144-way SPARC servers, 2-way to 8-way x86 servers, clusters, workstations.Early user and evaluator of prototype hardware and software. Provided optimization/requirements for future hardware design.

Lead performance group which wrote and optimized the audio (G.723.1) and video (H.263) compression code of a software video phone (H.324) which runs on Pentium based Personal Computers. Corresponded with manufacturers of video capture hardware to accomplish integration into the system. Interacted with sales and marketing in sales efforts.

Specified, designed, wrote and optimized code. Specific projects involved adding features and optimizing an H.261 video software package (for Pentium based systems); creating a control system from inception through completion of a video conferencing system; enhanced performance of a digital scene simulator (i860 based system).
