Profiling/Benchmarking Tools C++ Profilers C++ Profilers

GNU Profiler (gprof)

• ubiquitous, free software
• some IDEs can present gprof results in a GUI

Intel VTune Profiler

• free of charge
• GUI & command line interface
• sampling-based profiling
• hardware event sampling for Intel chips
• locks & waits analysis
• memory access analysis
• storage analysis
• integrates with MS Visual Studio

Coz – Causal Profiler

• unique approach to profiling
• creates causal profile: "optimizing function X will have effect Y"
• profile is based on performance experiments
• program is partitioned into parts based on progress points (that are set in source code)
• no additional instrumentation of source code required

NVIDIA Nsight Compute

• profiling for NVIDIA GPUs (architectures: Pascal, Volta, Turing)
• supplants NVIDIA Visual Profiler

AMD uProf

• sampling profiler for AMD CPUs and some AMD GPUs
