It arrives as part of the Intel toolchain, together with the Intel compilers and the Intel Math Kernel Library (MKL). Everything general about MPI — that it runs one program as many cooperating processes, that it has to be built into the program, and when it is the right tool at all — is covered on Multi-Process Workflows.

MPI — the Message Passing Interface — is how a single program runs as many cooperating processes at once, each with its own private memory, passing messages between themselves as the calculation proceeds. It is what lets one job use more than one node. This page is the practical side: which OpenMPI modules exist here, how to launch a job on one node and across several, and how to choose the network transport,...") | |||

This page is how a single calculation gets past that wall — not by growing one process, but by running '''many separate processes''', each with its own private memory, that send messages to each other as the calculation proceeds. The standard way to do that is '''MPI''', the Message Passing Inte...") | ||||

Instead of a heavy scientific code, it uses one friendly problem — estimating the number π by throwing random darts — and runs the ''same'' calculation across every kind of parallelism the cluster offers: a single core, many threads, many processes, multiple nodes, and a GPU. Because the problem stays the same, you can see exactly what each step up the ladder buys you. You do no...") | |||
