E.g. if shared data is read only for workers (i.e. updated only through control plane), you could build an ODP app that can handle process restarts. Multiple processes bring complexity to the memory mapping and init/startup phase (at least), but we cannot rule it out, since there'll be users / use cases that demand it. I think DKDP supports multiple separate processes. -Petri _______________________________________________ lng-odp mailing list [email protected] http://lists.linaro.org/mailman/listinfo/lng-odp
