Book: Using OpenMP – The Next Step

If everything goes according to plan, the book Using OpenMP – The Next Step will appear in time for SC17 (November 2017). The book is already available for pre-order on amazon:

From the book’s blurb:

This book offers an up-to-date, practical tutorial on advanced features in the widely used OpenMP parallel programming model. Building on the previous volume, Using OpenMP: Portable Shared Memory Parallel Programming (MIT Press), this book goes beyond the fundamentals to focus on what has been changed and added to OpenMP since the 2.5 specifications. It emphasizes four major and advanced areas: thread affinity (keeping threads close to their data), accelerators (special hardware to speed up certain operations), tasking (to parallelize algorithms with a less regular execution flow), and SIMD (hardware assisted operations on vectors).

As in the earlier volume, the focus is on practical usage, with major new features primarily introduced by example. Examples are restricted to C and C++, but are straightforward enough to be understood by Fortran programmers. After a brief recap of OpenMP 2.5, the book reviews enhancements introduced since 2.5. It then discusses in detail tasking, a major functionality enhancement; Non-Uniform Memory Access (NUMA) architectures, supported by OpenMP; SIMD, or Single Instruction Multiple Data; heterogeneous systems, a new parallel programming model to offload computation to accelerators; and the expected further development of OpenMP.

  1. Dear Christian,

    Can we consider Taskloop (SIMD) Construct with Depend Clauses inside Taskgroup is the Event Based Programming ?

    Thanks for your kind attention.

    Best regards,
    Henry Chan

    1. Hi Henry.
      What exactly do you understand as event-based programming? If you want to process an event loop in parallel, tasks + dependencies might offer a viable approach. But there are other use cases that are still not supported really well and remain on the agenda for a future version of OpenMP.

      Kind regards, Christian
