No, just submit it to the articus queue.

Will I need to recompile for articus?

Rob,

Can you try it on Articus instead?

Yarrow uses double-precision emulation and so I can imagine something easily going off the rails. Articus natively supports double-precision.

Hi,

Trying to run MPAS-Ocean on yarrow using OpenMP offloading. Getting a runtime segfault, but don’t get any core dumps. I’ve tried setting ‘ulimit unlimited’, but still no core dumps. How do I generate core dumps or is there an MPI-compatible debugger available on yarrow? I didn’t see totalview or ddt.

Thanks,Rob
