Libra: Scalable Load Balance Analysis
Software
·
OSTI ID:1231239
Libra is a tool for scalable analysis of load balance data from all processes in a parallel application. Libra contains an instrumentation module that collects model data from parallel applications and a parallel compression mechanism that uses distributed wavelet transforms to gather load balance model data in a scalable fashion. Data is output to files, and these files can be viewed in a GUI tool by Libra users. The GUI tool associates particular load balance data with regions for code, emabling users to view the load balance properties of distributed "slices" of their application code.
