[Beowulf] Profiling floating-point performance

[david moloney]

I have an application written in C++ which compiles under both MSVC++ 
6.0 and gcc 2.9.6 that I would like to profile in terms of floating 
point performance.

My special requirement is that I would like not only peak and average 
flops numbers but also I would like a histogram of the actual x86 
floating point instructions executed and their contribution to those 
peak and average flops numbers.

Can anybody offer advice on how to do this?  I tried using Vtune but it 
didn't seem to have this feature.
