Hi Paul,

As far as I know and to make sure I also checked the spec, they should 
be equal.

As the spec says in section 6.5.1.1:

"If the layout qualifier is of the form �[ * ]�, the shared object is 
distributed
as if it had a block size of
( sizeof(a) / upc_elemsizeof(a) + THREADS - 1 ) / THREADS,
where �a� is the array being distributed."

Regards,

Abdullah
