Is there a facility provided for profiling snapshots of fully optimized? E.g. application has been running for a day, now capture 2 minutes of profile data and analyze it (while application contiues to run).
How about of instrumented code?
Also what does it mean when the documentation says:
** Operating system counters can be sampled for each process.
How does this work? Is it using PAPI to query the counters?
Thanks for any help,
