|content=
# Modify the functions <tt>matvec</tt>, <tt>waxpby</tt> and <tt>dot</tt> to use OpenACC. You may use either the <tt>kernels</tt> or the <tt>parallel loop</tt> directives. The directories step1.* from the [https://github.com/calculquebec/cq-formation-openacc Github repository] contain solutions.
# Modify the Makefile to add <tt>-acc -gpu{{=}}managed</tt> and <tt>-Minfo{{=}}accel</tt> to your compiler flags.

Exercice : utiliser kernels ou parallel loop
  1. Modifiez les fonctions matvec, waxpby et dot . Vous pouvez utiliser soit kernels , soit parallel loop. La solution se trouve dans les répertoires step1.*.
  2. Modifiez le Makefile en ajoutant -ta=tesla:managed et -Minfo=accel aux indicateurs pour le compilateur.
