Arm MAP

Arm® MAP is a parallel profiler that shows you the longest running lines of code, and explains why. Arm® MAP does not require any complicated configuration, and you do not need to have experience with profiling tools to use it.

Arm® MAP supports:

• MPI, OpenMP, and single-threaded programs.
• Small data files. All data is aggregated on the cluster and only a few megabytes written to disk, regardless of the size or duration of the run.
• Sophisticated source code view, enabling you to analyze performance across individual functions.
• Both interactive and batch modes for gathering profile data.
• A rich set of metrics, that show memory usage, floating-point calculations, and MPI usage across processes, including:
  • Percentage of vectorized instructions, including AVX extensions, used in each part of the code.
  • Time spent in memory operations, and how it varies over time and processes, to verify if there are any cache bottlenecks.
  • A visual overview across aggregated processes and cores that highlights any regions of imbalance in the code.
