      Parallel programming with OpenMP

      OpenMP is an easy alternative to pthreads for multithread computing. OpenMP extensions now exist in most C and Fortran compilers and allow flagging loops and other construct for efficient multithreading with little supplementary programming effort. 

      Contents:

      • Parallel programming paradigms
      • OpenMP Execution model
      • Compiling an OpenMP program
      • Data races
      • Parallel loops
      • Barriers and synchronisation

      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 C or Fortran


      Type: Hands-on
      Target audience: Rookie programmer
      Must: This session is a must-have for anyone writing programs in C/C++ or Fortran

      Advanced SLURM job submission

      This session follows the first Slurm session and teaches participants how to enhance submission scripts using concepts learned in the Workflows, Parallel computing, Bash scripting, and MPI sessions.

       

      Contents:

      • Scripting submissions 
      • Arrays and Job packing 
      • Heterogeneous jobs 
      • Process placement 

      Prerequisite:

      • Being able to use SSH with private keys 
      • Being familiar with a text editor 
      • Mastering the Linux command line and Bash scripting
      • Working knowledge of Slurm

      Type: Hands-on
      Target audience: Everyone
      Must: This session is useful.
