"that the time is *always* in seconds"?
meaning that if I get a value of 0.4 in the user CPU this means that the time used for the
CPU to process it is 0.4*10E-9?
thank you very much for your previous reply. However
I'm still quite confuse
about the units of User CPU time in Experimenter. You said that User CpU
unit is in nanoseconds but then if you transform it to seconds to would have
to divide it by "10E6" then wouldn't that be microseconds and not
Sorry, CPU time first gets divided by 1000 and then by 10E6. Wasn't
clear from what I've written. The most important part from my post
was, that the time is *always* in seconds.
if i have a value of 0.04 for the user cpu time what
is it in seconds?
Could you please give me a concrete definition for the user CPU time? what
are we measuring here exactly? and what is the difference with cpu user time
and measure time?
UserCPU time is what the thread used in actual CPU cycles, hence most
accurate. Elapsed time is quite inaccurate, since it's only the
difference between the system's time (other processes/threads could
steal valuable processing time!).
I would like to compare different feature selection
methods by their
time consumption with respect to the time consumption of a classifier
without feature selection. Could you please suggest on which values i should
use? user CPU or measure time?
