compile code with large arrays in gfortran or ifortran

I have a fortran code where I have to declare an array with 600000 elements.

In order to compile the code with gfortran I use the flag -fmax-array-constructor=600000.

However, the same flag doesn't work when switching to ifortran. Do you know what flag I should use instead?

Solution

  • try making the array allocatable:

     real,allocatable::a(:)
 allocate(a(600000))
