That's correct. The executable size would reflect the extra
operations required to compute the offset for the doubly dimensioned
array.<br><br>

Right? <br>

<dd>HI,<br>
<dd>suppose we have four arrays with same number of elements say 60000.,
but different dimensions like:<br>
<dd>array1(1:60000)
<dd>array2(1:2, 1:30000)
<dd>array3(1:2, 1:300, 1:100)
<dd>array4(1:4, 1:15, 1:10, 1:100)<br>
<br>
<dd>Does each of these arrays in fortran will occupy same amount of
memory?<br>
<dd>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)? <br><br>
</dl>
<dd>They should take the same amount of space and have nearly identical
transfer times with MPI.<br>
<dd>(If you send the whole thing)<br><br>
<dd>-L</blockquote><br>
<dd>Those four array descriptors can all apply to exactly the same space,
via an 'equivalence' statement. They are all laid out in memory
just like array1. <br><br>
<dd>Thus, they can each be transmitted by exactly the same MPI
send.<br><br>
