Question about VTune for beginners

Dear all,
I am new to VTune and I have few questions regarding how to use it:
1. When I tried to sample a program using VTune, it ran several times. How to set it just to run once? In case it runs many times, are the results averaged or just summed up?
2. I would like to know how to get those information: number of branches, number of loops, number of memory accesses (load and store instructions) and total number of binary and bitwise operations.

Thanks and best regards,
Tuan

1. If you have selected several events besides the defaults, the sampling session must run several times in order to cover all your event selections.
2. Several of these events may be counted, but only in a sampling mode. The events differ according to your CPU architecture, but you should be able to find them in the event selection. I don't think there are selections for binary or bitwise categories.
