  1. Hierarchical Tic-Toc Timing/Memory Approach: [1] to add tic-toc functions calls on critical sections of the code. [2] to save information in a tree-based hierarchy. [3] to report information on different text based formats. [4] to report based on a single execution or collective operations • Objective: to add time/memory tracking features to nemo5 • Define tic-tocs points • Define hierarchical structure of tic-tocs • generate reports • Track Petsc allocated memory • integrate memory reporting to tic-tocs calls • Results: • A new Tic-Toc Implementation was added to Nemo5 (NemoTiming). • Nemo5 validates tic-tocs consistency (overlaped tic-tocs). • NemoTimingexports times in different formats XML, JSON, TXT, XLS (CSV). • Timing report supports time/memory aggregation.
