Subject: [PATCH 0/2 V3] Improve Coccinelle Parallelisation
Date: Wed, 7 Oct 2020 13:44:32 +0530 [thread overview]
Message-ID: <cover.1602054065.git.sylphrenadin@gmail.com> (raw)
Coccinelle utilises all available threads to implement parallelisation.
However, this results in a decrease in performance.
This patchset aims to improve performance by modifying cocciccheck to
use at most one thread per core by default in machines with more than 4
hyperthreads.
