[Beowulf] how to detect boundedness

["Toon Knapen" <toon.knapen@xxxxxxxxx>]

I would like to ask you all what your preferred method is to detect if and how strongly an application is cpu-, memory- or I/O-bound. Do you

1) just run the app. on different machines (with diff. characteristics)

2) use the profiler

3) use hardware monitors such as cache-miss rate, ...

....

 

Thanks in advance,
