How to measure memory bandwidth usage

2

I am trying to determine how close to being bandwidth-limited a code I have written is, so I was wondering whether there are any tools out there to determine memory bandwidth usage? The code I have is a command-line *nix code, and if possible I'd like to measure the bandwidth usage on Mac (but Linux is ok too).

in the equivalent of task manager (task monitor?) there isn't some that will tell you how much bandwidth a process has consumed? – soandos – 2012-08-06T11:33:36.533

You can use cachegrind. Memory bandwidth is essentially the same as misses in the lowest-level cache.
