Current work

• Research and development of HPCToolkit for measurement and analysis of application performance measurement, analysis and tuning of important science and engineering applications at the direction of the DOE Office of Science as part of the SciDAC PERI, CScADS projects, PIPER and ECP.
• Research, development, and evaluation of programming models for scalable parallel systems. This work on both global view programming models (related to DARPA's HPCS program) and partitioned global address space languages (PGAS), including UPC and Coarray Fortran.
