We can choose three different conventions while using `staggeredPhaseQuda` to apply the staggered phase to a gauge field. `QUDA_STAGGERED_PHASE_CPS` should apply the CPS software's staggered phase, wh…

Right now, we do not really care about the block-size. But especially when it comes to multiple RHS it will matter. We should implement an autotuner like quda has. One has to think of a good design. T…

Hi Balint,
Yesterday afternoon I built QUDA/develop on Frontier (apparently)

We should probably do two things:
1. finally remove the --enable-gpu flag and all the gpu stuff that Florian added about a decade ago. (we…
