Representative timings for a basic CG solve on several computers are
given below.
The model problem solved is 
on the unit square, discretized with five-point central differences,
with uniform mesh size 
and Dirichlet boundary data.
The unpreconditioned conjugate gradient method is used.
Single precision real arithmetic is employed.
It should be emphasized that these figures are preliminary and do not reflect
all code optimizations which are currently under development for the package.
