Veritomyx is a bioinformatics startup attempting to sequence peptides using mass spectrometry data in collaboration with parent company, Target Discovery Inc.

Global technical marketing position supporting applications of importance to HP massively parallel computing customers. Most recent applications included the UK Met office climate and weather models, the chemistry code NWCHEM, and the bioinformatics codes, NCBI BLAST, Autodock, ClustalW, HMMER and FASTA. Activities included performance optimization, porting, benchmarking and key customer support.After participating in a project to convert a 5+ million line, multi-language silicon compiler code from a 32-bit memory model to a 64-bit memory model, I rigorously stress tested the HP compiler optimization isolating several bugs using the code. I designed a representative customer benchmark suite to be used in profile based optimization and proved to the ISV that it could meet production release standards. It is the first and still the largest ever to achieve release in my organization. I did the first evaluation and release of Sockets Direct Protocol over Infiniband in a major application.

Support of shared-memory and message-passing parallel computer sales to technical and scientific customers including presentations, benchmarking and post-sales support. Applications include shock-hydrodynamics, plasma physics, RADAR cross-sections, CFD, ocean modeling, HDTV image processing, seismic forward modeling, quantum chemistry, molecular dynamics, etc. Working with Caltech and JPL, I assisted in the porting and optimization of the Parallel Ocean Program from a Cray T3D with shared-memory message passing to MPI. This effort was subsequently featured and acknowledged in poster sessions, conference proceedings, technical reports and papers.

on-site applications analyst working with the scientists at the Sandia National Laboratory, nCUBE's most significant scientific customer and beta test site. Leveraged the value of nCUBE computers to this customer and the value of the work performed at this site to nCUBE. Significantly influenced the design of Teraflop versions of both the nCUBE 3 and future nCUBE 4 systems as the technical lead in nCUBE's response to the Sandia RFQs for the ASCI program (Advanced Strategic Computing Initiative). Modified nCUBE's A/D, D/A and DIO drivers, testing the corresponding hardware components. Found and fixed related operating system bugs. Co-authored two papers in computational chemistry. Co-chaired the Workshop on Migration and Parallel Computing at the 1991 annual meeting of the Society of Exploration Geophysicists.

Interviewing, hiring, training and mentoring pre- and post-sales analysts while being one myself. Benchmarked the usual range of applications on nCUBE's distributed memory massively parallel MIMD CISC computer. Tracked down and reported compiler and chip bugs. nCUBE's first employee who's primary office was his home.

Supported the structural analysis applications (ABAQUS, ANSYS, MARC, NASTRAN, SOLVIA), and maintained and improved Alliant's math libraries. Implemented a new highly tuned solver for ABAQUS. Prepared for and worked the NASTRAN and ANSYS user's group trade shows. Split the math library into three products, tuning the BLAS3. Earlier I was responsible for the Oil Industry applications and the floating point ECAD codes (circuit and device simulators, etc.). Ported Western Atlas Integrated Technologies' Core and Encore programs, and supported the Seismograph Services Corporation, an Alliant OEM account. Debugged and produced Alliant's parallel version of Berkeley SPICE, and supported the Motorola (memory products group, MTIME) and MetaSoftware accounts (HSPICE). The seminal BLAS3 and LAPACK contributions were acknowledged by Jack Dongarra.The only non-sales employee whose primary office was in the home.

Provided pre and post sales technical support to Alliant's salesmen and customers in the South Central Region. Converted and optimized for Alliant's parallel computers, software from a broad range of application areas, including seismic modeling and migration, seismic processing, reservoir simulation, chemistry, physics, ECAD, MCAD, computational fluid dynamics, image processing, simulation.Excelled at code optimization, isolating hardware, system, compiler and application problems, and analysis of competing computer systems. First at Alliant to implement coarse grained parallelism using multiple processes (a cruise missile clobber program). One of three field analysts hired before first production shipment. One of two Alliant employees whose primary office was in the home.

Provided support for the first FPS-264 installed in a major oil industry account. Optimized customer applications and benchmarks.

I worked on a project oriented basis out of an office in my home and reported to marketing in Beaverton, Oregon. Responsibilities included testing and demonstrating the capabilities of the company's latest products on oil industry applications. Helped conclude a marketing agreement with a major reservoir simulation software vendor and performed the conversion and optimization of their code for the FPS-164. Converted a major migration and velocity filtering code to utilize the large memory and multiple processors of the FPS-5000. Provided technical support to the seismic OEM and large oil company accounts. Played a key role in winning FPS's first 64-bit OEM account. Represented FPS with the Vector Processing Consortium of the Allied Geophysical Laboratories of the U. of Houston. Was instrumental in securing FPS's participation in this consortium and FPS's contribution of a 3 co-processor 5430. Pin-pointed hardware problem at a customer site which impacted more than half FPS's installed base of co-processors. Wrote an application note and a Checkpoint article on the performance of the new CPFORTRAN compiler and demonstrated its use with single page mathlibraries and table memory.

Provided technical support and presentations to salesmen and customers on the complete line of FPS products, the AP120B, FPS-100, FPS-164 and the FPS-5000 series. Converted and optimized several customer applications to run on the FPS-164, including 4 reservoir simulators, 4 seismic forward modeling programs, a well logging induction model, an analog circuit simulator (SPICE), a device simulator (MINIMOS), 3 quantum chemistry applications, 2 quantum physics applications, air flow analysis, radar simulation, real-time seismic correlation and stacking, passive submarine detection and medical imaging via nuclear magnetic resonance. Since much of this work was done at a beta test site, experience was gained debugging and modifying system software and micro-coding the exotic architectures.

At the Seismic Acoustic Laboratory, I implemented on the CYBER 203 and 205, a two-dimensional forward modeling program and the polynomial pre-conditioned conjugate gradient algorithm (PPCG), obtaining a working knowledge of CYBER 200 FORTRAN, including special calls and half-precision machine instructions; the CYBER 200 operating system; the NOS operating system; and the CYBER 200 hardware architecture. Trained new research assistants and taught a class on the CYBER 200 series.My PPCG work was included in the CYBER 205 math library and later in ITPACKV and NSPCG at the University of Texas.Co-authored and presented paper to consortium meeting.

Autumn 1980 taught two FORTRAN courses and an assembly language lab using a Honeywell computer. Spring 1981 taught two assembly language labs using the DEC VAX 11/780.
