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...") | ||||
