SUMMARY Presented is a massively parallel implementation of the Optimal Transportation Meshfree (pOTM) method Li et al. , 2010 for explicit solid dynamics. Its implementation is based on a two‐level scheme using Message Passing Interface between compute servers and threaded parallelism on the multi‐core processors within each server. Both layers dynamically subdivide the problem to provide excellent parallel scalability. pOTM is used on three problems and compared to experiments to demonstrate accuracy and performance. For both a Taylor‐anvil and a hypervelocity impact problem, the pOTM implementation scales nearly perfectly to about 8000 cores. Copyright © 2014 John Wiley & Sons, Ltd.
