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.

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.

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..

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).
