Storage systems on leadership-class machines can deliver tens of gigabytes of performance at peak, yet applications frequently see much less performance in practice. High Level I/O libraries such as HDF5 can bridge the gap between application I/O and the storage system. This seminar will give an introduction to using the HDF5 library, with a focus on parallel I/O and performance tuning options.

Quincey has been with The HDF Group since its founding and started with the HDF team in 1991, when it was still part of the National Center for Supercomputing Applications. He serves as the Director of Software Development, overseeing the design and architecture of the HDF5 software, as well as providing software engineering leadership. Quincey received his Bachelor
