From fc4241827fffc761f0ca41536c1c7d88b1b1d0c4 Mon Sep 17 00:00:00 2001 From: Thomas Huth Date: Wed, 17 Feb 2021 12:19:31 +0000 Subject: [PATCH] travis.yml: Limit simultaneous jobs to 3 MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Even though the host machines that run the Travis CI jobs have quite a lot of CPUs (e.g. nproc in an aarch64 job reports 32), the containers on Travis are still limited to 2 vCPUs according to: https://docs.travis-ci.com/user/reference/overview/#approx-boot-time So we do not gain much when compiling with a job number based on the output of "getconf _NPROCESSORS_ONLN" - quite the contrary, the aarch64 containers are currently aborting quite often since they are running out of memory. Thus let's rather use a fixed number like 3 in the jobs here, so that e.g. two threads can actively run while a third one might be waiting for I/O operations to complete. This should hopefully fix the out-of-memory failures in the aarch64 CI jobs.
