 Throughput experiment for the pattern in patterns/xrage/asteroid/spatter9.json. Results will be found in spatter.strongscaling/H100/xrage/asteroid/spatter9/ and Figures will be found in figures/spatter.strongscaling/H100/xrage/asteroid/spatter9/
 
+Note that we need to enable atomics with the `-m` flag since this is a scatter pattern which overwrites the same location multiple times. Results with and without atomics are included, but the results with atomics enabled is the benchmarked performance number of importance.
