5 Summarizing an existing MAP file

Arm Performance Reports can be used to summarize an application profile generated by Arm MAP. To produce a performance report from an existing MAP output file called profile.map, simply run:


   $ perf-report profile.map

Command-line options which would alter the execution of a program being profiled, such as specifying the number of MPI ranks, have no effect. Options affecting how Performance Reports produces its report, such as --output, work as expected.

For best results the Performance Reports and MAP versions should match, for example, Performance Reports 18.2.1 with MAP 18.2.1. Performance Reports can use MAP files from versions of MAP as old as 5.0.
