When a piece of software does not work the way it is expected to, it needs debugging. Then, when it works, it needs profiling to remove the bottlenecks. This session will also present the standard optimized librairies that will allow you to code faster and more efficiently.
Contents: Debugging principles The GNU debugger (gdb) The Intel debugger Advanced features of Intel Cluster studio the support of MIC architecture (Xeon Phi) the Guided Auto Parallelism the Coarray Fortran support Intel MKL	Prerequisite: Being able to use SSH with private keys  Being familiar with a text editor  Mastering the Linux command line and the GNU utilities (mkdir, cp, scp, etc.) Passive knowledge of either C, Fortran, Octave, Python or R Working knowledge of C or Fortran Familiarity with OpenMP and MPI
	Type: Hands-on Target audience: Programmers Must: This session is important for programmers who want to optimize their code for usage on a cluster.
