Seminar Title: Building High Performance Post-Processing Tools with the Polyhedral Model
Speaker: Cathie Olschanowsky, Assistant Professor, Boise State University
Date/Time: 2020-07-08 10:30
Location: Virtual
Description:
The polyhedral model represents iteration and data access patterns commonly found in scientific applications. However, the impact of polyhedral-enabled optimizations is limited due to the challenges of incorporating it into legacy applications. These applications run in a production environment and their developers are reluctant to use research software that may disrupt stable operations. In this talk I propose rebuilding pre- and post-processing tools as a way to solidify optimization software and gain access to smaller application codes that exhibit the same patterns. This talk highlights the I/O performance gains and improvements in reproducibility for post-processing tools demonstrated with the Parflow application.
