I find that micctrl --resetconfig takes a long time on our system (>15 minutes). I suspect the reason is that we have thousands of user accounts in our cluster environment and the command spends time configuring each one. After the command is run, the /etc/passwd file for the mic card is populated with every user and we must remove them all so that they can be added manually on demand by the prologue script of our batch system. I cannot find any mention in the documentation of a way to prevent this command from configuring the mic cards for our entire list of users.
My question is, what alternatives are there to micctrl --resetconfig for quickly pushing a small change to the configuration (for example, when changing the hostname as in this forum topic: http://software.intel.com/en-us/forums/topic/401009)? Is there a way to manually change the configuration without using this command? Or are there additional options for this command that will give me more control over what changes will be made?
Thanks in advance.
