[Beowulf] How to analyze application cache coherency?

[Christian Nygaard]

How would you analyze application use of CPU cache on the AMD64, Intel Core
platform?

I have a set of different applications running in a cluster and a scheduler
that distributes jobs on the cluster nodes lets call the applications A,B,C.
What I would like to analyze is which mixes of applications goes well with
CPU cache on each node and which combination would be optimal to enhance the
job distribution scheduler. The system is running Linux 2.6.19 64bit kernel.

node1: AAAAAAAA
node2: BBBBBBBB
node3: ABCABCAB

What Linux tools would you use to analyze this? Could you show some examples
on how to use it to look into CPU cache performance of an application?

Thanks for your input,
Chris
