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.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.
