Background & Purpose：

In order to make full use of modern supercomputer systems with multicore/manycore architectures, hybrid parallel programming with message-passing and multithreading is essential. MPI for message-passing and OpenMP for multithreading are the most popular ways for parallel programming on multicore/manycore clusters.

This 4-day tutorial provides essential knowledge and experiences for parallel programming using MPI and OpenMP. Hands-on exercise by the Readbush-U supercomputer at the University of Tokyo (Intel Broadwell-EP) is also given. (https://www.cc.u-tokyo.ac.jp/system/reedbush/index-e.html).

In this course, OpenMP, MPI and OpenMP/MPI Hybrid are applied to 3D Poisson equation solver by finite-volume method (FVM) with preconditioned conjugate gradient iterative method (PCG). Detailed lectures on data structure for parallel FVM, as well as fundamental trainings for MPI and OpenMP are also provided.

The 4th day of the course will be spent for lectures and hands-on on more advanced topics, such as automatic tuning (AT), and large-scale parallel computing.
