WebIn the data parallel paradigm, multiple CPU’s run the same program and the data is shared in common. Each CPU runs the same commands on a different piece of data. This works well when the same operation needs to be performed on many pieces of data at the same time. This is the way GPU’s are designed to operate. WebCOSMOSDG uses a message passing interface (MPI) library to run simulations in parallel across a large number of processors. I explored the possibility of running multiple OpenMP processes that utilize shared memory within each MPI process. Finally, COSMOSDG is intended for open-sourced, public development and use.
