The Coz profiler, a nice +profiler able to run benchmarking experiments on the instrumented +multi-threaded program, finally +made it into +Debian unstable yesterday. LluÃs Vilanova and I have spent many +months since +I +blogged about the coz tool in August working with upstream to make +it suitable for Debian. There are still issues with clang +compatibility, inline assembly only working x86 and minimized +JavaScript libraries.
+ +To test it, install 'coz-profiler' using apt and run it like this:
+ ++coz run --- /path/to/binary-with-debug-info ++ +
This will produce a profile.coz file in the current working +directory with the profiling information. This is then given to a +JavaScript application provided in the package and available from +a project web page. +To start the local copy, invoke it in a browser like this:
+ ++sensible-browser /usr/share/coz-profiler/viewer/index.htm ++ +
See the project home page and the +USENIX +;login: article on Coz for more information on how it is +working.
