al basis set and
high latency of the IBM violated all the criteria for good performance
with the old algorithm. With the new code the Fock-build is completely
dominated by integral computation.

 <P> The global array tools make it very easy to express
blocked algorithms since the library provides routines that enable
each process to access patches of arrays independently of all other
processes.  This asynchrony makes the program easier to write and also
more efficient since there are no unnecessary synchron
