Comment (by cpernet):
Eventhough openmp is enabled in `fflas-ffpack̀` and `linbox`, the current
code called by sage does not use any OpenMP parallelism.
If you think it is necessary, I could pass the `--disable-open` argument
to the configure scripts. Thanks for pointing out that linbox still forces
the -fopenmp evenif --disable-omp was passed to configure. We'll fix it.
Regarding the use of a threaded BLAS: it is possible to run the sequential
code of `fflas-ffpack` on top of a parallel BLAS, but one will achieve
much better performances by running the parallel code of `fflas-ffpack`
(with OpenMP enabled) on top of a sequential BLAS. This will need further
discussions when we'll want to have sage run its linear algebra kernels in
parallel.
