System was operational less than 2 weeks after hardware was installed.Helped establish MVS/TSO system tuning and performance measurement methodology. Used techniques to solve initial performance problems. Later developed a workload management strategy. Implementation of the strategy proved to be highly successful. Participated in the annual workload management/capacity planning cycle.Participated in Model 204 relational DBMS analysis, evaluation, and documentation as member of the Model 204 Pilot Project. Provided Model 204 consulting during implementation phases. Group leader of MVS/TP group which successfully stabilized MVS while migrating from 3350 to 3380 DASD, updated the MVS service level, and installed new functions. Project leader for initial implementation of VM/CMS.Project leader for handling special system requirements of Reservoir Modeling and Seismic Processing applications. Planned and coordinated the installation of seismic graphics display system called CRYSTAL. Provided innovative solutions to large memory requirements of reservoir models like ALPURS. Developed special software to read old one inch seismic field tapes and copy to modern half inch tapes. Assisted IBM with hardware/software fault analysis in the 3838 array processors and 7350 Advanced Image Processing System (AIPS).Helped develop the installation plan and strategy for MVS/XA and IBM 3090 mainframe.

Information Services - Manager, IBM Operating System Development and Planning - Jul 81 - May 78Supervised 5 senior systems specialists and programmers who evaluated, installed, tested, maintained, and modified MVS and JES3 and developed major subsystems to support bulk data transfer, remote job entry, and network job entry for nodes in the TI computer network.Was project leader for the conversion of the Dallas Center (6 - 3033s) from MVS 3.7 and JES3 2.1 to MVS 3.8 and JES3 3.0. This involved a matrix organization using resources (15 people) from development, support, operations, and production scheduling organizations. Had responsibility for system build, TI modification conversion and integration via SMP4, integration testing, system testing on production configuration, and quality assurance.Was project leader for the development of the BDT system. This involved a matrix organization using resources (10 people) from two development groups. BDT/370 was developed for IBM nodes and BDT/990 was developed for TI nodes. Was designer/architect of the overall BDT system. General and detail designer of BDT/370. Designed and personally helped develop the BSC multi-leaving link and SNA full-duplex session protocols used for communication between nodes. The BDT/370 system was purchased by IBM and was released as a program product called MVS/BDT. Received corporate level recognition, Senior Member of Technical Staff, for development of BDT system.Information Services - Senior Technical Specialist - May 78 - Jul 74Contributed to the conversion of the Dallas Center (multiple CPUs, 150 RJES, etc.) from SVS and ASP3 to MVS and JES3. Converted and enhanced TI's RJE package (SIO) and other modifications. Made major performance modifications to JES3 output service which helped permit conversion after two failed attempts.
