      Reductions represent a common algorithmic pattern in many scientific applications. OpenMP* has always supported them on parallel and worksharing constructs. OpenMP 3.0’s tasking constructs enable new parallelization ...
    • Towards transactional memory for OpenMP 

      Wong, Michael; Ayguadé Parra, Eduard; Gottschlich, Justin; Luchangco, Victor; De Supinski, Bronis; Bihari, Barna (Springer, 2014)
      Conference report
      Open Access
      The OpenMP specification lacks a composable shared memory concurrency mechanism: the current OpenMP concurrency mechanisms, such as OMP critical, locks, or atomics, do not support composition. In this paper, we motivate ...
