This question is a bit off-topic, but since it involves Fortran
minutia,
I figured this would be the best place to ask. This code may
eventually
run on my cluster, so it's not completely off topic!
Question: What is the maximum number of elements you can have in a
double-precision array in Fortran? I have someone creating a
4-dimensional double-precision array. When they increase the
dimenions
of the array to ~200 million elements, they get this error:
compilation aborted (code 1).
I'm sure they're hitting a Fortran limit, but I need to prove it. I
haven't been able to find anything using The Google.
It is not Fortran restriction. It may be some compiler restriction.
64-bit ifort for EM64t allow you to use, for example, 400 millions
elements.
