Synchronization problem when moving agents in a context with UndirectedSharedNetwork and SharedCSpace projections

I am building on the rumor model (from the repast4py tutorial) to create a model in which agents can move in a 2-dimensional continuous space, and whose actions will depend on the states of nearby agents and some distant agents (according to a given…

I am trying to create an OrderBook agent that can be shared across all ranks. I can share the agent using mpi4py send and receive operations. But based on the documentation here I am assuming self.context.synchronize(restore_orderbook) will create…
