Number of Memory Accesses

[Junaid Jameel Ahmad]

Paul,

Thanks for your to the point questions.

I am interested in all the memory accesses when the process is
running. However, it will also be useful if I can also know how many
of these memory accesses just ended in cache and did not went to the
main memory.

Yes it will be also helpful too to distinguish the amount of accesses
contributed by each source (my own process, shared library, system
calls etc). It will simply make my analysis more concrete.
