Generating performance bounds from source code

Dr. Krishna Narayanan, Mathematics and Computer Science Division, Argonne National Lab, USA

22 Apr 2014, 15:45–17:15; Location: S4|10-1

In this talk he will discuss the source analysis tool PBound, that estimates the upper performance bounds of C and Fortran applications. Built on the ROSE compiler framework, PBound generates parametrized expressions for different types of memory accesses and integer and floating-point computations. Additionally, PBound uses application reuse distance analysis to model memory behavior. Architectural parameters are then incorporated to estimate upper bounds on the performance of the application on the particilar system. He will also present validation results for several codes on two architectures and show examples of PBound`s use in autotuning. He will also discuss extensions that are planned.
