thanks for the reply. My main concern in this program test is not
about low level compiler but to know which coding practise is
effecient in a general sense. I mean, which code will be better
optimized by the compiler if i choose to use the compiler optimization
option.

thanks for the reply.
The general case is talked about somewhat in MR&C 6.9. The example they
look at is array assignment that doesn't seem markedly different than what
you had in the original post. So at first blush and knowing next to nothing
about compiler optimization, I would say that the formulation with the
forall would lend itself better to optimization on parallel processors.
