Aggregate bandwidth (GiB/s) for writing 10-component simulation grids of varying sizes to Lustre. Each data point shows the statistical mean over 5 writes, with the standard deviation shown in error bars. The lack of data points for the 1283 and 2563 grids at large numbers of writers are configurations with more MPI processes than total Boxes, such that some portion of processes would write no data.
