Description

This option specifies the name of a Message Passing Interface (MPI) configuration file. This file is used by the compiler when coarrays are processed; it configures the MPI for multi-node operations.

This option has no affect unless you also specify option -coarray (Linux* OS) or /Qcoarray (Windows* OS), which is required to create the coarray executable.

Note that when a setting is specified in environment variable FOR_COARRAY_CONFIG_FILE, it overrides the compiler option setting.
