[CSC 435] Speedup Graph Generator

[Andrew J. Pounds]

It can be a pain to generate the data for a speedup plot.  Most students
load all their data into a spreadsheet, process it there, and then dump
it back to hammer for processing by gnuplot to determine the fit to
Amdahl law.  Yuck. 

I wrote a little perl script that will take process/runtime data in two
colums like this.

1 1000
2 505
3 400
4 260
5 210
6 185

and create the following.

*cobra:~ **%***perl speedup.pl speedup.dat
Procs    Time    Speedup
1    1000    1
2    505    1.98019801980198
3    400    2.5
4    260    3.84615384615385
5    210    4.76190476190476
6    185    5.40540540540541

It is on the class webpage in the EXAMPLES section where you find the
gnuplot script for Amdahl's law.
