In these tutorials, you will learn a wide array of concepts about MPI. Below are the available lessons, each of which contain example code. The tutorials assume that the reader has a basic knowledge of C, some C++, and Linux.Myocardial perfusion imaging (MPI) is a non-invasive imaging test that shows how well blood flows through your heart muscle. It can show areas of the heart muscle that aren’t getting enough blood flow. It can also show how well the heart muscle is pumping. This test is often called a nuclear stress test.

The first concept is the notion of a communicator. A communicator defines a group of processes that have the ability to communicate with one another. In this group of processes, each is assigned ... This option should be passed in order to build MPI for Python against old MPI-1 or MPI-2 implementations, possibly providing a subset of MPI-3. If you use a MPI implementation providing a mpicc compiler wrapper (e.g., MPICH, Open MPI), it will be used for compilation and linking. This is the preferred and easiest way of building MPI for Python.
