Multitheading in C++ Unavailable

Question

Dear all,

I read the posts on multithreading with OpenMP, knowing that there might be some errors when enabling that.

However, it seems that in Fenics 1.5.0 OpenMP isn't enabled at all, as has_openmp() returns false.

It there any possibility of having multithreading working?

Thanks!

PS. Yes, I could use MPI, I know, and it works flawlessly on my system :)

DOLFIN build you use isn't probably configured with OpenMP. You need to build DOLFIN with OpenMP enabled by yourself. Or you could also check if some of virtualization images provided on http://fenicsproject.org/download have OpenMP enabled.
