Jens Domke (U. of Dresden) - Static routing in fat tree network model including ground work for dumping the topology and reading the routing tables. Xu Yang (IIT) - Added support for running multiple application workloads with CODES MPI Simulation layer, along with supporting scripts and utilities. Noah Wolfe (RPI): - Added a slim fly network model based on the topology proposed by Besta, Hoefler et al. - Added a fat tree network model that supports full and pruned fat tree network. - Added a multi-rail implementation for the fat tree networks (pending). - Bug reporter for CODES network models. Caitlin Ross (RPI): - Added instrumentation so that network models can report sampled statistics over virtual time (pending). - Bug reporter for CODES models.
