Hello....
He is a new idea of mine about USL..
When you do your testing to collect performance data
on the parallel program , if you have 4 cores,you have to test
for 1,2,3,4 cores, for example test 10 times for 2 cores, and
test 10 times for 3 cores and test 10 times for 3 cores and test 10
times for 4 cores, and calculate after that the standard deviation
between the 10 times of the tests for each case, if this standard
deviation is greater that means that you can not forecast scalability
too far with my USL programs, and that means you can forecast
scalability to about 2X times the maximum number of cores of the
performance data that is in this example 4 cores, but if the standard
deviation is small , so you can forecast scalability with my programs
too far to about 4X or 5X or even 6X times the maximum number of cores
of the performance data that is in this example 4..hope you have
understood my methodology that Dr. Gunther the author of USL didn't tell
you about.
So my USL programs will work efficiently this way...
Thank you,
