## Overview ## Overview
EARL is dynamically loaded next to the running applications by the [EAR Loader](EAR-Loader). EARL is dynamically loaded next to the running applications by the [EAR Loader](#ear-loader).
The Loader detects whether the application is MPI or not. The Loader detects whether the application is MPI or not.
In case it is MPI, it also detects whether it is Intel or OpenMPI, and it intercepts the MPI symbols through the PMPI interface, and next symbols are saved in order to provide compatibility with MPI or other profiling tools.
