Event-Action Mappings for Parallel Tools Infrastructuresrting, and debugging often motivate the use of tools, many of which operate at application runtime. Current trends in the HPC community, such as increasing compute core counts and the advent of new programming paradigms challenge the development of applications, as well as the development of runtime

Low-Overhead Detection of Memory Access Patterns and Their Time Evolutionp analysts understand the accesses to the application data structures. This information is captured using the Precise Event Based Sampling (PEBS) mechanism from the recent Intel processors, and it is correlated with the source code and the nature of the performance bottlenecks if any. Consequently,

Automatic On-Line Detection of MPI Application Structure with Event Flow Graphside users with means to spot bottlenecks in their applications by either collecting aggregated statistics or generating lossless time-stamped traces. While obtaining detailed trace information is the best method to examine the behavior of an application in detail, it is infeasible at extreme scales
