Description

This option specifies the default number of images that can be used to run a coarray executable.

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. This option is required to create the coarray executable.

You can specify option [Q]coarray-num-images to specify the default number of images that can be used to run a coarray executable. If you do not specify that option, you get the number of execution units on the current system.

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