c++ - Eigen multi-thread operations -

eigen c++ template library linear algebra (site). according documentation, newer eigen versions support usage of openmp take advantage of multi-threading characteristics. official documentation mentions some operations can ran in paralell (documentation).

however, -concrete- operations susceptible of these advantages not mentioned in place. place have been able find states matrix , vector multiplication can ran in parallel, no more information provided (here).

i appreciate if share bit of knowledge uncertainty.

from eigen's source directory:

$ find eigen -type f | xargs grep -i openmp 

...shows general matrix matrix product (gemm) using openmp (for now!).
