Detailed Description

WO-9b instrument: wall time of advance_scalars on G-perf's 128^3 bed (dt D/h^2 = 1, koren,
Dirichlet spheres) after 3 flow steps; NS timed advances (env N = cells per axis, NS). The CUDA
profiler range wraps the timed advances (nsys --capture-range=cudaProfilerApi). On host, run with
KOKKOS_TOOLS_LIBS = the Kokkos simple kernel timer at NS=0 and NS=k and difference the two tables:

  NS=3 OMP_NUM_THREADS=1 KOKKOS_TOOLS_LIBS=<kp_kernel_timer.so> PYTHONPATH=build_dev \
      python advance_profile.py > kt3.txt          (and NS=0 > kt0.txt)
  python advance_profile.py diff kt0.txt kt3.txt 3
