Abstract :
Characterization of high-performance computing applications often has to be done without access to the source code. Computer architects, therefore, have a narrowed choice of instrumentation tools. Moreover, potentially large amount of collected data can prohibit creating a full time stamped event trace and analyzing it post-mortem. This paper describes Limpio -- a Light weight MPI instrumentation framework, that allows dynamic instrumentation of user-selected MPI calls, and customization of data gathering, analysis and visualization.
