MPIBYTE
MPIBYTE refers to a specific data type within the Message Passing Interface (MPI) standard. MPI is a standardized and portable message-passing system designed for use on parallel computing systems. It provides a set of routines for communication between processes, enabling parallel programs to be written for distributed memory architectures. The MPI standard defines various built-in data types that represent different primitive data types, such as integers, floating-point numbers, and characters, in a way that is independent of the underlying hardware and operating system.
MPIBYTE is one of these predefined data types. It corresponds to a single byte of data. When
