       guess_concurrency.py

SYNOPSIS

       guess_concurrency.py [-h] [--detect METHOD] [--max N] [--min N] [--require-mem MEMLIST]

DESCRIPTION

       Guess  a suitable concurrency level given constraints from the runtime environment. Environment variables
       such as DEB_BUILD_OPTIONS, RPM_BUILD_NCPUS  and  CMAKE_BUILD_PARALLEL_LEVEL  are  consulted  for  initial
       guesses  falling  back to querying the operating system in order to guess a suitable concurrency level. A
       user may further restrict the emitted concurrency by specifying a minimum or  maximum  and  by  requiring
       sufficient memory to support a level of concurreny to be available.

OPTIONS

       --detect METHOD
              supply a processor count or select a detection method (nproc, python or cores)

       --max N
              limit the number of detected cores to a given maximum

       --min N
              limit the number of detected cores to a given minimum

       --require-mem MEMLIST
              specify per-core required memory as a comma separated list
