Parsing PRF files

Is there any document describing the PRF format in detail?
I've seen that this file is a nested collection of entries enclosed by '{' and '}' but I would like to known detailed timestap, callee and caller components, etc.

Thanks in advance,
Sergi Valverde

hi,

as far as I am informed the "PRF" format is neither opened nor documented for external users.

Is there any official confirmation on this?

I would like to build the call graph from the "PRF" file (v-tune 4.0) for research purposes only. My desire is to do path profiling[1] but don't know if v-tune 4.0 is able to do so. Such analysis should be easy to do from the annotated call graph that the "PRF" file seems to encode.

Cheers,
Sergi Valverde
