* Testing the sample R program from www
 * Original R Program (without Rmpi)
 * Parallel R Program (with Rmpi)
 * Here are the running times(secs) with different times of loops of origianl R:
{{{
10 loops : 1.087226
20 loops : 3.395167
30 loops : 7.027248
40 loops : 11.95344
50 loops : 17.02942
60 loops : 23.54457
70 loops : 32.23314
80 loops : 42.41104
90 loops : 53.88992
100 loops : 64.43279
}}}

 * And Here are the running times(secs) with diffrent times of loops of PARALLEL R (Rmpi):
{{{
10 loops : 1.759266
20 loops : 2.582305
30 loops : 4.262631
40 loops : 6.176133
50 loops : 8.695369
60 loops : 12.00457
70 loops : 16.19619
80 loops : 20.33303
90 loops : 25.45973
100 loops : 30.71952
}}} 

* The Curve is like this:[[BR]]
 the Y aix means single mode runtime minus parallel runtime.[[BR]]
 the units is seconds.[[BR]]
 X aix means loop times (from 10 to 100) [[BR]]
