My account Guide and Reference Special Terms Standard data processing and mathematical terms are used in this book.
Terminology is generally consistent with that used for Fortran.
See the Glossary for more definitions of terms used in this book. Reference reports may use the term decomposition to mean the same thing. Indicates an argument does not have to be coded and is assigned a default value if the argument is not present. Referenced reports may also use the terms processor or node to mean the same thing. For one-dimensional process grids, the variables p and np are used interchangeably to indicate the number of processes in a row or column of the process grid.
