Description
Caliper+Thicket is LLNL’s ubiquitous performance analysis software suite for optimizing HPC applications. Caliper and Thicket are complementary libraries that let users manually add lightweight performance instrumentation directly into their applications while deciding the granularity of information they want to collect and analyze during each application run. The resulting performance profiles reveal data of both breadth and depth, informing comparisons across runs and at scale.
Caliper+Thicket capabilities are particularly useful for large multiphysics simulation codes running on the world’s largest supercomputers, such as the codes and HPC systems deployed at LLNL, other scientific institutions, and other major computing centers. These libraries are open source, free, and available to the public on GitHub (https://github.com/llnl/Caliper, https://github.com/LLNL/thicket).
