	   Numbers abound.  "Experience with Linda" (Bjornson et. al.,
YALEU/DCS/TR-866) has data on codes doing matrix multiplication, LU
decomposition, parallel sequence comparison, fluid dynamics and more.
Linda tech reports can be obtained from Chris Hatchell
(hatchell@cs.yale.edu).

	Without knowing more about your problem, there is not much I
can say other than to note that Linda programs routinely run on much
larger collections of machines.

   	BTW, with respect to a comment from an earlier posting, SCA's
next release (v2.4.7, in use now at Yale) supports multiple processes
per node.
