Antoine Pitrou updated ARROW-8012: ---------------------------------- Component/s: Continuous Integration > [C++][CI] Set CTEST_PARALLEL_LEVEL to $concurrency > -------------------------------------------------- > > Key: ARROW-8012 > URL: https://issues.apache.org/jira/browse/ARROW-8012 > Project: Apache Arrow > Issue Type: Improvement > Components: C++, CI, Continuous Integration > Affects Versions: 0.16.0 > Reporter: Ben Kietzman > Priority: Major > > Currently the default {{test}} target runs serially while {{unittest}} > arbitrarily uses 4 threads. On many systems that's suboptimal. The > environment variable {{CTEST_PARALLEL_LEVEL}} can be set to run tests in > parallel, and we should probably have a good default for it (like the > hardware concurrency) > https://cmake.org/cmake/help/latest/manual/ctest.1.html -- This message was sent by Atlassian Jira (v8.3.4#803005)
