I have installed DMTCP 1.2.4 on our cluster and was wondering if there
are any recommendations on configuring it for a cluster enviroment?
Specifically I am not clear whether the dmtcp_coordinatator process be
started on each node or only on the head node? Also if a user starts
dmtcp_coordinator with automatic checkpointing (checkpointing interval >
0), would this policy also apply to another user? Finally how to limit
user checkpointing intervals (i.e. not allow a user to set a too small
interval)? Thanks.
