  The operational space and global performance of plasmas with edge-localized
modes (ELMs) suppressed by resonant magnetic perturbations (RMPs) are surveyed
by comparing AUG, DIII-D, EAST, and KSTAR stationary operating points. RMP-ELM
suppression is achieved over a range of plasma currents, toroidal fields, and
RMP toroidal mode numbers. Consistent operational windows in edge safety factor
are found across devices, while windows in plasma shaping parameters are
distinct. Accessed pedestal parameters reveal a quantitatively similar
pedestal-top density limit for RMP-ELM suppression in all devices of just over
3x1019 m-3. This is surprising given the wide variance of many engineering
parameters and edge collisionalities, and poses a challenge to extrapolation of
the regime. Wide ranges in input power, confinement time, and stored energy are
observed, with the achieved triple product found to scale like the product of
current, field, and radius. Observed energy confinement scaling with
engineering parameters for RMP-ELM suppressed plasmas are presented and
compared with expectations from established H and L-mode scalings, including
treatment of uncertainty analysis. Different scaling exponents for individual
engineering parameters are found as compared to the established scalings.
However, extrapolation to next-step tokamaks ITER and SPARC find overall
consistency within uncertainties with the established scalings, finding no
obvious performance penalty when extrapolating from the assembled multi-device
RMP-ELM suppressed database. Overall this work identifies common physics for
RMP-ELM suppression and highlights the need to pursue this no-ELM regime at
higher magnetic field and different plasma physical size.
