 Timing calibration ; time = 592.05609671772 hundredths of a second
 Increase the size of the arrays if this is <30
  and your clock precision is =<1/100 second

Assignment: 34.4371 0.9395 0.9292 0.9596
Scaling : 36.6877 0.8909 0.8722 0.9106

 Note: this program was linked with -fast or -fnonstd
 and so may have produced nonstandard floating-point results.
 Sun's implementation of IEEE arithmetic is discussed in
 the Numerical Computation Guide.
