[Lombardi, Johann]

I am afraid that the rank is used internally as an index in an array. As a consequence, it is still expected to be fairly “dense” and unique across all the XStreams, even when managed by the user. ABT_key_create/set/get/free allow you to allocate private storage for each ULT/tasklet. In our project, we use pthread_key_create/delete to manage per-XStream local storage.

Cheers,
Johann

Thanks for the reply Johann!

So, it can be treated as meta data that the "user" can attach and read, that isn't used anywhere in the low-level argobots implementation?

Cheers,

Ben.
