Performance Tools ¶ NERSC provides many popular profiling tools. MAP : MAP is a parallel GUI sampling tool for performance metrics; time series of the collected data for the entire run of the code is displayed graphically, and the source code lines are annotated with performance metrics.

Performance Reports : Performance Reports is a low-overhead tool that produces one-page text and HTML reports summarizing and characterizing both scalar and MPI application performance. Reveal : Utilizing the HPE Cray CCE program library for source code analysis and performance data collected from CrayPat, Reveal helps to identify top time-consuming loops and provides compiler directive suggestions for inserting OpenMP parallelism.

Roofline Performance Model : The Roofline performance model offers an intuitive and insightful way to compare application performance against machine capabilities, track progress towards optimality, and identify bottlenecks, inefficiencies, and limitations in software implementations and architecture designs.

NVIDIA profiling tools : Nvidia performance analysis tools are available on Perlmutter. These offer the capacity to get an overview of your applications performance using Nsight systems or take a more detailed look at an individual kernel using Nsight compute. mpiP, a lightweight profiling library for MPI applications, is a very useful tool for collecting statistical information on the MPI functions.

mpiP generates considerably less overhead and much less data than tracing tools. It only uses communication during report generation, typically at the end of the experiment, to merge results from all of the tasks into a single output file. TAU is a powerful performance evaluation tool, which supports both parallel profiling and tracing.

Profiling and tracing allows you to not only measure time but also to see hardware performance counters from the CPUs. To use TAU's automatic source instrumentation, you will have to set some environmental variables and substitute the compiler name with a TAU shell script.

Python Classes User Forums Tech Talk Knowledge Sharing Sessions. USING DISCOVER. The gprof command The GNU profiler gprof is a useful tool for locating hot spots in a program.

It displays the following information: The percentage of CPU time taken by each function and all functions it calls its descendants.

A breakdown of time used by each function and its descendants. How to use gprof: Compile and link all code with the -pg option. Run the program as usual. When it completes you should have a binary file called gmon. out, which contains runtime statistics. View the profile statistics by typing gprof followed by the name of the executable and the gmon.

out file, which will construct a text display of the functions within the program call tree and CPU time spent in every subroutine. out MPI profiling: mpiP mpiP, a lightweight profiling library for MPI applications, is a very useful tool for collecting statistical information on the MPI functions.

The application does not have to be recompiled to use mpiP. mpiP is a link-time library. mpiP will work without -g.

So yes benchee is more for measuring performance before something goes live or for testing out multiple approaches locally, from what I understand you want to have more of an introspection into the running system.
