Shgrid timing table

The execution times for Shgrid are essentially linearly proportional to the number of output data points (doubling the number of output data points will double the execution time).

The following table is offered as an example of execution times. The times were obtained on a Sun sparc Ultra-1 running SunOS 5.5.1 using version SC4.2 of the C compiler:

Number of input points Number of output points Time in Secs.
50 1000 0.30
100 1000 0.57
200 1000 1.33
400 1000 2.77
