Hi All,

I am trying to solve my PDE using openmp in a shared memory computer. The code solves heat equation using a default direct solver. It looks that the code’s performance does not change much when I modified `export OMP_NUM_THREADS=xxx`. Does dolfinx v0.10 support Openmp if installed from conda? It appears that the legacy dolfin did not: [openmp support for dolfin](https://fenicsproject.discourse.group/t/openmp-support-in-fenics-2019/7203).

We do not have specific openmp support at the moment, and parallelism is obtained by using MPI to distribute meshes, matrices and vectors across multiple processes.
