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.

On Intel® MIC Architecture, this option is only available on Linux* systems.

This option has no affect unless you also specify the [Q]coarray option, 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.
