I am also working on parallel processing for my Phd and implementing a Redis-based distributed shared memory queueing system that looks a lot like a tuple space. The Redis primitives fit this messaging model perfectly, allowing very loose coupling between language-neutral computational elements. I do have concerns that the single-threading may eventually impose a bottleneck with the scale of deployment intended (1000s of CPUs and GPUs). I have been looking into 0MQ to overcome these limitations and wonder how feasible it would be to implement a 0MQ socket connection option for Redis.
