Please let me know if you encounter any problems with the update. -- Michael J.

If you are an inactive user with no upcoming plans, please do not fill out the survey. If you are active and do have plans or currently running compute jobs, please complete this survey in the next few days. It will only take a few minutes of your valuable time. I need to schedule a maintenance window which will require a full system reboot including the file server and all compute nodes. Your help in completing this survey will be used to schedule a window during the coming weeks that has a minimal impact to everyone. *SURVEY* *For all users:* 1) Do you plan to run any multi-day jobs any time soon? 2) How long do you expect these jobs to run? Be as specific about this as you can. 3) What is your deadline associated with this work? 4) What is the latest date that you would be able to start your currently planned compute jobs? *For people running jobs currently:* 5) Which machines are you running jobs on right now? 6) Try to estimate how long you expect these jobs to complete. Be as specific about this as you can. 7) Are any or all of your jobs interruptable (and able to be resumed) at some checkpoint of your job? Explain if you can. 8) Please share anything else that you feel is pertinent. The idea here is that I need to determine when the earliest time that the current jobs can be completed or interrupted sensibly, and determine the latest time that currently planned multi-day jobs can be started. I am not really concerned about jobs that run for only a few hours since even if I need to interrupt them forcibly, they can be easily re-ran quickly without too much inconvenience.

This work will be completed before Wednesday. Things to know: * Your work will continue to run in the background of this work, but will only be given a small percentage of available compute cycles. * If this work has any 'quiet times', your work will receive normal priority. * If for some reason the memory is fully exhausted on the machine during this work, your jobs may be automatically terminated by the Linux Kernel OOM (out of memory) killer. This is not likely or expected to happen during this work, but it is worth noting. * If your work is not time-sensitive before Wednesday, we do suggest stopping your jobs at a convenient spot and resuming them after Wednesday. * I can administratively pause any low priority (but long running) jobs, so if your job falls into that category, please let me know. If you want to pause it yourself you may run killall -s SIGSTOP yourprocessname # to pause and, killall -s SIGCONT yourprocessname # to continue processing Thanks for helping us free the clicks we need to make this important deadline.
