 ## Multi-GPU Benchmarks
 
-Multi-GPU benchmarks are done at the largest possible grid resolution with a cubic domain, and either 2x1x1, 2x2x1 or 2x2x2 of these cubic domains together. The multiplicator numbers in brackets are relative to single-GPU results.
+Multi-GPU benchmarks are done at the largest possible grid resolution with a cubic domain, and either 2x1x1, 2x2x1 or 2x2x2 of these cubic domains together. The percentages in brackets are single-GPU roofline efficiency, and the multiplicator numbers in brackets are scaling factors relative to benchmarked single-GPU performance.
