Following the discrepancy noticed by Tapan (https://vo.uabgrid.uab.edu/sympa/arc/r-group/2008-09/msg00020.html) and Enis (https://vo.uabgrid.uab.edu/sympa/arc/r-group/2008-09/msg00024.html), John-Paul mentioned that we can gauge this discrepancy, if we do some test runs same as in the MIG three-parameter case. so, here are the timings for the test runs on different clusters. The R-code used was the latest with the six parameters. The number of iterations that the MIG script ran on varied from 10, 20, 30, 40, 50, and 100. The run script looked like this:

R --silent --no-save --no-restore "--args n=10 f=50 p=0.3 r=0.3 a=0.05 m=0.1 e=10 st=1" < MigAnalysis.R
R --silent --no-save --no-restore "--args n=10 f=50 p=0.3 r=0.3 a=0.05 m=0.1 e=20 st=1" < MigAnalysis.R
R --silent --no-save --no-restore "--args n=10 f=50 p=0.3 r=0.3 a=0.05 m=0.1 e=30 st=1" < MigAnalysis.R
R --silent --no-save --no-restore "--args n=10 f=50 p=0.3 r=0.3 a=0.05 m=0.1 e=40 st=1" < MigAnalysis.R
R --silent --no-save --no-restore "--args n=10 f=50 p=0.3 r=0.3 a=0.05 m=0.1 e=50 st=1" < MigAnalysis.R
R --silent --no-save --no-restore "--args n=10 f=50 p=0.3 r=0.3 a=0.05 m=0.1 e=100 st=1" < MigAnalysis.R
