Communication in X direction maybe broken for scalar build #10

Open diptorupd opened 9 years ago

Scalar in the sense of no MPI? What happens that lets it appear broken?

I will close this, if that comes up again or we get more info, we can re-open.

I think maybe in the sense of no vectorization? I think the scalar code doesn’t work in X (and we haven’t really suported scalar).

Best, B

Yes, originally Scalar code was added to allow running QPhiX code on BG/Q. We have some issue when running multinode with comms needed in X direction.
