I'm distributing a set of independent tasks over different processes, so I'm afraid sending everything to the zeroth process would rather thoroughly defeat the purpose of what I'm doing.

It sounds like you're going to run this a bunch of times. Does it have to be sequential (gather to one rank at a time) or can it be an alltoall?
