HI, suppose we have four arrays with same number of elements say 60000., but different dimensions like: array1(1:60000) array2(1:2, 1:30000) array3(1:2, 1:300, 1:100) array4(1:4, 1:15, 1:10, 1:100) Does each of these arrays in fortran will occupy same amount of memory? For sending/receiving each of these, Does MPI has the same (or nearly same) overhead? or any significantly different overhead is involved in handling each of these arrays (by MPI)? with best regards, Amjad Ali -------------- next part -------------- An HTML attachment was scrubbed...
