openMP support in dolfinx v0.10

dolfinx

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.

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.
