(a) The time to complete 300 difference-map iterations for various node counts and 32 threads per node. (b) The time for the maximum-likelihood refinement to reach a specific error value limit for various node counts and 32 threads per node. (c) The I/O time to read the data and write the reconstruction result for various node counts and 32 threads per node. The effect of increased synchronization time for larger numbers of nodes is clearly visible. |
