GPU branch code item work list
-----------------------------
7) Accelerate the cshift
7) Accelerate the cshift & benchmark
* 0) Single GPU
- 128 bit integer table load in GPU code.
- coalescedRead <- threadIdx.x
- Gianluca's changes to Cayley into gpu-port
- GPU accelerate EOFA
- Staggered kernels -> GPU coalesced loop
- Staggered kernels -> GPU coalesced loop, loop in kernels
- Staggered kernels inline for GPU -- DONE
* 2) 5D terms & Gianluca
* Gianluca merger
- Cayley coefficients -> GPU retention or prefetch
- Mobius kernel fusion. -- Gianluca?
- Make GPU offload reductions optionally deterministic -- Gianluca
- Gianluca's changes to Cayley into gpu-port
- Mobius kernel fusion. -- Gianluca?
- Make GPU offload reductions deterministic -- Gianluca merge
- Lattice_reduction - remnant thread_loops must offload. Audit thread_loop in main code for non-accelerated code
* 3) Comms/NVlink
- OpenMP tasks to run comms threads.
- OpenMP tasks to run comms threads. Experiment with it
- Remove explicit openMP in staggered.
- Single parallel region around both the Kernel call
and the comms.

* 5) Misc
- Conserved current clean up.
- multLinkProp eliminate
8) Merge develop and test HMC
9) Gamma tables on GPU; check this.
9) Gamma tables on GPU; check this. Appear to work, but no idea why. Are these done on CPU?
10) Audit
- pragma once uniformly
- Audit NAMESPACE CHANGES
