Given the usual Pentium-level processors now commonly available and the amount of memory these systems typically contain, the program we have developed can deal (optimally) with object set sizes in the lower teen’s, but even this requires the capability of Fortran90 to allocate very large arrays dynamically (and inform the user whether sufficient memory exists on the system to solve the problem of the size being requested).
