# This outputs a graph of time(N), the us it takes to execute N empty batches.
# e.g. 110 59 34 22 16 13 11 10 10 10 9 4 1.4 1.4 1.2 0.9 0.8
# As a summary, print the number of nop/s (so that it matches the bigger is
# better motif of fps).
#
# Ideally we want to run this per ring,
# gem_exec_nop:rcs, gem_exec_nop:bcs, gem_exec_nop:vcs
# though for the time being just one will suffice
