Re: [Condor-users] memory usage info

[Joe Meehean <jmeehean@xxxxxxxxxxx>]

Actual memory usage is a bit difficult to define 
and also very difficult to get from the OS.  Many 
people use RSS (resident set size), but this 
doesn't really reflect *actual* memory usage due 
to page sharing (who should get the bill for 
glibc?).  Additionally, RSS is not a good measure 
of the memory a program needs, only of what it can 
get  (it may need more, it may need less).
