From 558ceabc6c08f275ce6c6e7ff295e74272eb851a Mon Sep 17 00:00:00 2001 From: Klement Sekera Date: Thu, 8 Apr 2021 19:37:41 +0200 Subject: tests: cpus awareness Introduce MAX_CPUS parameters to control maximum number of CPUs used by VPP(s) during testing, with default value 'auto' corresponding to all CPUs available. Calculate test CPU requirements by taking into account the number of workers, so a test requires 1 (main thread) + # of worker CPUs. When running tests, keep track of both running test jobs (controlled by TEST_JOBS parameter) and free CPUs. This then causes two limits in the system - to not exceed number of jobs in parallel but also to not exceed number of CPUs available. Skip tests which require more CPUs than are available in system (or more than MAX_CPUS) and print a warning message.
