At NCI, we provide researchers with profilers so that they can improve their code performance with a clear guidance. We tested four profiling tools and show the corresponding examples below.
| profilers | CPU | GPU | MPI | function level | source-code level | high level performance summary |
|---|---|---|---|---|---|---|
| PProf.jl | x | x | x | |||
| Intel-Vtune | x | x | x | x | ||
| NVidia Nsight |
| Systems | x | x | x | x | ||

PProf.jl
This tool shows the information collected by the native Julia profiler through a graphic user interface. One can navigate through the profiling result by the statistics, flamegraph, and calling graph view and use the search bar to find any piece of code under interest.
