I am wondering, if using multiple threads (using fopenmp) would speed up eigen's cholesky decomposition

<https://eigen.tuxfamily.org/dox/classEigen_1_1LLT.html>

There is some information about eigen that specific methods can run parallel, but it is not clear which one benefit

<https://eigen.tuxfamily.org/dox/TopicMultiThreading.html>

If eigen does not have the option of parallel decomposition, maybe there is another option?
