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