The characterize_data script uses multi-processing for concurrency. ITK filters use multi-threading as part of each process. There is the potential for contention when too many threads are created as compared to the number of available cores on the CPU. The solution here is to set ITK to run in single threaded mode and the speedup is obtained from the parallel processes.
