FIGURE 19.4: VPIC-IOBench weak scaling study. Shows I/O performance
with increasing number of processes writing data to a HDF5 file using H5Part.
FIGURE 19.5: Performance of writing a single HDF5 file of 34 TB to Lustre.
The eight peaks correspond to writing the eight variables of particle data,
using all the available file system bandwidth. After writing each variable,
synchronization occurred. Overall, the achieved I/O performance was 78% of
the peak performance.
