deregisterFromBarrier()
Just found this function in SyncClient.
Is there more detail plan for this?

In my opinion, this function is useful when you want to relieve a BSP Peer
to close and free the Task slot on Groomserver while other peers have few
more superstep to work on. I know our current barrier implementation would
fail with that. Will be working on this as a part of the BSP Peer API
improvements.
For fault tolerance, especially when checkpointing received messages, I
did not need this function. The nodes being ephemeral gets deleted in the
scenario when I restart peer processes.

That's (probably) used in Suraj's fault tolerance works when a task needs
to be removed from the host lists and the barrier.
