[Mpi3-hybridpm] Reminder for telecon tomorrow

[Douglas Miller]

I am definitely thinking about OpenMP and how best to use it, but of course
we can't depend on it being used in all cases so we have to have solutions
that work with pthreads or other mechanisms for parallelism.

Dear all,

I subscribed to this list only recently in order to get an impression on
how MPI is evolving concerning hybrid parallelization.
I am participating in the OpenMP Language Committee and I am wondering in
how far OpenMP is of any concern.

Best regards,
Dieter
