if random array generation is excluded from time measurement, the mean time difference between 1-core and 80-core processing is larger
the main contribution to time difference comes from reserved host...
- sdfmilan047 - looks like extremely "time-noisy" in multi-core processing...
- sdfmilan031 - in previous test looks pretty "calm"

19 Test for a few hosts

The same simulation algorithm as before is used to compare processing time of different cores.
To get rid of obvious fluctuation off time measurement between cores, subset of cores is extended from three cores, 0,30,60 to seven cores 0,10,20,30,40,50,60 of 80.
Mean processing time and its uncertainty in milliseconds for single core (core 0/1) and a few cores of 80 are shown in table.
Ratio represents the ratio of 80-core average over core 0/1.
