How to do call graph profiling in XE?

I installed the Amplifier XE demo today and not sure how to do call graph profiling.
I have some cases that are not cpu bound yet are slow and really need to see the flow.

I have other cases where I want to know how often some data conversion functions are called for coverage verification and weighting which ones to do first (for AVX implementation)

Looking at GlowCode also as an alternate for these types of scenarios.
I do hope Amplifier can do it.

Thanks!

Hi Keith,
Now VTune Amplifier XE 2011 supports user-mode sampling (Hotspots, Concurrency, LocksAndWaits) with statistical call graph - which means you can view call stack of each hot function to know its callers, in Bottom-up report.
For overview of call sequence, you can view Top-down report.
Thanks, Peter
