This training will present basic elements first to enable developpers to understand when and how to use a debugger, and second to optimize the performance of their codes.

Debugging :

A short introduction to debugging with examples
Optimization :

 Basics (stripping, IOs, getting the calculations out of the loops, changing the algorithm, ...)
 Compiler options 
 Vectorization - Data access (cache usage maximization)
 OpenMP parallelization strategies
 Theory to upper-bound the expected performance benefit (speedup, efficiency, peak, memory bandwidth, ...)
Half of the course will be made of hands-on sessions. The hands-on will use the https://github.com/aff3ct/MIPP library

Trainers

Bertrand Cirou
Mathieu Cloirec
Cédric Jourdain
Learning outcomes 
Ability to understand the main issues for code optimization, knowledge of the main tools and techniques for basic debugging.Prerequisites 
Basic knowledge of Unix, programming experience in C++, OpenMP
