Description

I've started on the OMPSS version now, with the initial code compiling, and a few implementations of some tasks.

Currently its setup so everything other than time_step_ompss.o is build using gcc/gfortran/g++, and that object file and the final linking is done with mcxx

Right now, nothing will run unless I use OMP_NUM_THREADS=1, as I get a seg fault in:

Program received signal SIGSEGV: Segmentation fault - invalid memory reference.

Backtrace for this error:

@rupertford do you have a contact in OmpSs we could ask about this issue with? Clearly without being able to launch multiple threads we'll have issues using tasks efficiently 😆
