> Which profilers can > benefit from all this info? We have found Oprofile to be a useful text-oriented tool: http://oprofile.sourceforge.net/about/ >From the Overview on this page: "OProfile is a system-wide profiler for Linux systems, capable of profiling all running code at low overhead. OProfile is released under the GNU GPL.
It consists of a kernel driver and a daemon for collecting sample data, and several post-profiling tools for turning data into information. OProfile leverages the hardware performance counters of the CPU to enable profiling of a wide variety of interesting statistics, which can also be used for basic time-spent profiling. All code is profiled: hardware and software interrupt handlers, kernel modules, the kernel, shared libraries, and applications." -Tom > > This monster suite (free!): > http://www.cs.uoregon.edu/research/tau/docs.php > Which I have been pushing around for a while and it's quite impressive > IMHO.
