 |
|
What is the equivalent of -mcmodel for compiling fortran program on windows.
this page talks of /heap-arrays[:size] option for windows for Intel compiler
Is there such option available for pgfortran. Please let me know how to force stack variables to move on heap. |

There isn't one since the medium memory model requires OS support and Windows does not support it. Though, this only effects static memory. For large (> 2GB) dynamically allocated arrays, you can add the flag "-Mlarge_arrays".

"-Mnostack_arrays", but this is our default behavior so the flag is not needed. To set the stack size, please use the link time flag "-stack=<reserve>[:<commit>]".
