# This test tries to ensure that -j runs tests in parallel.
# Such a test is inherently racy, because there are no real-time
# guarantees about scheduling delays.  So we try to minimize
# the chance to lose the race.

# The time needed for a micro-suite consisting of NTESTS tests each
# sleeping for a second is estimated by
#   startup + ntests * (serial_overhead + 1 / njobs)
#
# in absence of major scheduling delays.  This leads to side conditions:
# - NTESTS should be high, so the STARTUP time is small compared to the
#   test run time, and scheduling delays can even out; it should not be
#   too high, to not slow down the testsuite unnecessarily,
# - the number of concurrent jobs NJOBS should not be too low, so the
#   race is not lost so easily; it should not be too high, to avoid fork
#   failures on tightly limited systems.  4 seems a good compromise
#   here, considering that Autotest spawns several other processes.
# - STARTUP is assumed to be the same for parallel and serial runs, so
#   the latter can estimate the former.
# - To avoid unportable output from time measurement commands, spawn
#   both a parallel and a serial testsuite run; check that the former
#   completes before the latter has completed a fraction SERIAL_NTESTS
#   of the tests (the serial run is executed in a subdirectory), plus
#   some additional time to allow for compensation of SERIAL_OVERHEAD.
# - when adding this time to the serial test execution, an initial delay
#   SERIAL_DELAY of the serial test helps to avoid unreliable scheduling
#   due to the startup burst of the suites.
