This topic addresses the syntax of blocking MPI routines for sending and/or receiving point-to-point MPI messages.
Objectives
After you complete this topic, you should be able to:
- Explain the signature for send commands
- Define parameters for C and Fortran
- Explain the purpose of coupled communication calls.
- Distinguish between swap and chain communications
Prerequisites
- Familiarity with HPC paradigms and MPI Basics.
- Experience programming in a high-level language such as Fortran or C would be helpful, but the reader can still follow along to understand the concepts and methodologies.
- A basic familiarity with parallel programming concepts
