Ian posted a patch to do something like this - I think he wanted a hash table that was shared across all processes. The problem gets to be growing the memory space, but I think his use case was with fixed memory. He could probably tell more about how he wanted to do it. Both rbb and I suggested that this is what SMS was designed for. Have a SMS that is backed by shared memory and then the hashtable immediately becomes shared when you create it with this shared memory SMS. No change needed to the hashtable code. And, potentially, the scoreboard could (??) get switched to something using a shared memory SMS. But, I don't know enough about the scoreboard to say more about that. -- justin
