Chief, Advanced Computing Section
Global Systems Division
I manage the Advanced Computing Section, a software group that supports model development, parallelization, and porting to high performance computers, and explores advanced computing technologies for GSD, ESRL and NOAA. I have a background in high-performance computing, code parallelization and compiler development.
- Bachelors of Science, Computer Science, University of Colorado, Denver, 1991
- Masters of Science, Computer Science, University of Colorado, Boulder, 1995
I have diverse interests in high performance computing including Graphical Processors (GPUs), Cloud Computing, Distributed Data Access, Web Portals, and software engineering to improve model performance, portability, and interoperability. I believe GPUs are the next major advance in HPC and that Cloud Computing can be used to effectively distribute data. I believe portals are needed to support the development, configuration and testing of increasingly complex modeling systems. Finally I am interested in improving software engineering practices that enhance sharing models across NOAA and with our collaborators.
- Developed the Scalable Modeling System (SMS) compiler to translate Fortran codes into performance portable code that can be run on most HPC systems.
- Led the exploration of Grid Computing at NOAA. Deliverables included developing a prototype grid that linked multiple NOAA sites.
- Led the development of WRF Domain Wizard, and WRF Portal that support model development and testing.
- Wrote a Fortran-to-GPU translator and used it to parallelize NIM. This code runs 25 times faster than on the CPU.
