copyExtendedColorSpinor functions does not support Mobius fermion field #694

Open hummingtree opened 6 years ago

It seems the copyExtendedColorSpinor functions in lib/extended_color_spinor_utilities.cu does not recognize the extra 5th dimension for domain-wall/mobius fermions. I don't know if this is something that will be supported in the near future?

Thanks,

Hi @hummingtree. The copyExtendedColorSpinor function is essentially deprecated, as it doesn't have the full functionality desired. The plan is to extend the framework used for extending gauge fields, to also work with color-spinor fields as well.

Thanks @maddyscientist. It would be great if quda could support the extension of 5-dim fermion field. We(RBC/UKQCD) are trying to implement a new preconditioner for CG which needs this badly. I don't know if you have any idea about when this functionality will be implemented?
