Nice to see multi-thread assembly being added. We should look at adding
support for the multi-threaded version of SuperLU. What other
multi-thread solvers are out there?
I haven't looked at the code in great detail, but are element tensors
being added to the global tensor is a thread-safe fashion? Both PETSc
and Trilinos are not thread-safe.
Rather than having two assembly classes, would it be worth using OpenMP
instead? I experimented with OpenMP some time ago, but never added it
since at the time it required a very recent version of gcc. This
shouldn't be a problem now.
