The identification of performance bottlenecks in parallel applications is a challenging task. Without some form of performance measurement tool, this task lacks any guidance and purely relies on trial-and-error. At the same time, data sets from parallel performance measurements are often large and overwhelming. We provide an effective solution to automatically identify and highlight several types...
The complexity of today's high performance computing systems, and their parallel software, requires performance analysis tools to fully understand application performance behavior. The visualization of event streams has proven to be a powerful approach for the detection of various types of performance problems. However, visualization of large numbers of process streams quickly hits the limits of available...
