Yes, but the concurrency model is distinct, and more or less unrelated, in my understanding. >> The problem that I'm concerned about is at a different level. >> Say that some process, after completing its work, is deleting >> a bunch of stuff.

Well, (rhetorical question:) why would they? If there's "background inference" being performed on these sentences, then clearly the NLP system is buggy if it's trying to delete them -- this would be a straight-forward programming error. As to attention allocation: it would presumably be attention allocation that decided "we're done with these sentences, so clear them out of RAM". Both these issues are in the domain of the concurrency model, which is more or less unrelated to the multi-threading model, as I understand it. --linas p.s. as to concurrency: I am currently hacking up a multi-stage NLP pipeline, where processing happens in several stages, which must happen in sequential order, and I'm using little marker nodes to tag/flag different sets of atoms as being complete, or waiting for processing. Its sort of a hack just so I can move on to other things, but if there's some "standard" way of declaring that processing for some collection of atoms is "done", and is ready to be handed off to the next stage, I'm all ears. _______________________________________________ Mailing list: https://launchpad.net/~opencog-dev Post to : [email protected] Unsubscribe : https://launchpad.net/~opencog-dev More help : https://help.launchpad.net/ListHelp
