NAME

       coz - profiler running experiements on multithreaded code

SYNOPSIS

       coz run [profiling options] --- <command> [args]

       coz plot [-h]

DESCRIPTION

       Coz  is  a  new  kind  of  profiler  that  unlocks  optimization  opportunities  missed by
       traditional profilers. Coz employs  a  novel  technique  we  call  causal  profiling  that
       measures  optimization  potential.  This measurement matches developers' assumptions about
       profilers:  that  optimizing  highly-ranked  code  will  have  the  greatest   impact   on
       performance.  Causal  profiling  measures optimization potential for serial, parallel, and
       asynchronous programs without instrumentation of special handling for  library  calls  and
       concurrency primitives. Instead, a causal profiler uses performance experiments to predict
       the effect of optimizations. This allows the profiler to establish causality:  "optimizing
       function  X  will have effect Y," exactly the measurement developers had assumed they were
       getting all along.

OPTIONS

       -h, --help
              show this help message and exit

       --binary-scope <filepattern>, -b <filepattern>
              Profile matching executables. Use '%' as a wildcard, or 'MAIN' to include the  main
              executable (default=MAIN)

       --source-scope <filepattern>, -s <filepattern>
              Profile matching source files. Use '%' as a wildcard.  (default=%)

       --progress <source file>:<line number>, -p <source file>:<line number>
              [NOT SUPPORTED] Add a sampling-based progress point

       --output <profileoutput>, -o <profileoutput>
              Profiler output (default=`profile.coz`)

       --end-to-end
              Run a single performance experiment per-execution

       --fixed-line <source file>:<line number>
              Evaluate optimizations of a specific source line

       --fixed-speedup <speedup> (0-100)
              Evaluate optimizations of a specific amount
