[Trilinos-Users] creating Tpetra maps from off-processor data

[Templeton, Jeremy Alan]

Hi all,

We are trying to create importers for a particle scheme which which communicate on-processor data to neighboring processors.  We have seen some codes creating custom Zoltan_Comm_Obj’s to do this task such that the processor figures out which particles it needs to send to which other processors and executes that through the Zoltan_Comm_Obj.  We think we can accomplish this same task using the Teuchos comm with non-interrupting sends and receives.

However, this seems to be a lot of effort to do something which seems like a common and high-level task: create a map from distributed information to be used with an importer.  So the question we have is: is there functionality within Tpetra/Teuchos which can more directly perform this task?

Thanks,
Jeremy
