Review comment:
Ubuntu offers multiple OpenBlas packages. Serial, pthread and openmp
based. You can refer to
https://packages.ubuntu.com/search?suite=default§ion=all&arch=any&keywords=openblas&searchon=names
I'd guess that adopting serial OpenBlas is not an option due to potential
slowdown. If you think it might be ok, it would be great to run a benchmark to
check before making a decision.
