Set the machine switch according to the characteristics of the system on which KAP Fortran output runs. This capability is available to prevent concurrentization on applications that have small inner loop bounds, thereby reducing overhead costs. When the loop bounds are unknown at compile time, KAP Fortran may generate concurrent code for innermost loops, a practice that may be inefficient for the actual loop bounds.
Some computers perform better if consecutive references are contiguous in memory.
To disable all of the switch settings, enter -nomachine on the command line.
