Tools

Darshan: a scalable HPC I/O characterization tool. Darshan is designed to capture an accurate picture of application I/O behavior, including properties such as patterns of access within files, with minimum overhead.
Dyninst: Dyninst is an API and related library for the dynamic instrumentation of binaries. It allows programs to be modified during execution without recompilation or re-linking. Used by performance measurement and other tools.
HPCToolkit: HPCToolkit is an integrated suite of tools for measurement and analysis of program performance on computers ranging from multicore desktop systems to GPU-accelerated supercomputers. By using statistical sampling of timers and hardware performance counters on CPUs, HPCToolkit collects accurate measurements of a program’s CPU work, resource consumption, and inefficiency and attributes them to the full calling context in which they occur.
PAPI: The Performance Application Programming Interface (PAPI) offers a universal interface and methodology for gathering performance counter information from diverse hardware and software components.
TAU: TAU (Tuning and Analysis Utilities) is capable of gathering performance information through instrumentation of functions, methods, basic blocks, and statements as well as event-based sampling.
