A desktop application for visualizing Massif memory profiling data produced by Valgrind.
Valgrind's Massif tool profiles heap memory usage in your programs, capturing snapshots of memory allocation over time.
Cordillera takes the .out files generated by Massif and transforms them into interactive visualizations, making it easy to identify memory hotspots,
track allocation patterns, and optimize your application's memory footprint.
