• 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:
  the Y aix means single mode runtime minus parallel runtime.
  the units is seconds.
  X aix means loop times (from 10 to 100)
