hi folks, excuse the ignorance of this question, but suppose you had 1,250 systems hooked up to a networking fabric with 10usec end-end propogation times, but the times can vary depending upon contention. What I want to know is this: how accurately can NTP sync the clocks across all those machines? I know it may be asking for too much, but is it possible to get 1usec accuracy? If it makes it any easier, this is a controlled environment, so it is possible to have a tree structure in the nodes such that the times fanout very quickly to all nodes.
If it can't be done with NTP, anyone have any suggestions on how to do this with a software solution?
Thanks.
