Background

It is well known that real-life scientific computing codes normally do not achieve very good performance on a modern computer. In order to identify the "bottleneck", it is important to do a profiling of a code. PAPI is a collection of APIs for accessing hardware performance counters, based on which a performance profile can be deduced. http://icl.cs.utk.edu/projects/papi It is the purpose of the thesis work to try PAPI on Diffpack programs (http://www.diffpack.com).

What You Will Do

• Install and test PAPI
• Use PAPI on a typical Diffpack program
• Do performance improvement by recoding parts of Diffpack libraries

What You Will Learn

• Hardware performance counters
• Profiling
• Performance tuning/optimization of C/C++ codes
