Surveyor and Gadzooks systems will have their regularly scheduled preventive maintenance period this coming week.

During this time, no jobs will be run on the systems, there may be disruptions in filesystem access and there may be disruptions in network access to the login nodes.

We will notify users when the work has been completed and the machines are again available for general use. Please email support at alcf.anl.gov with any questions or concerns.

*** Cobalt Tips for Groups ***
Users working together are often inconvenienced because the person who submitted a job is the only one who can modify or delete it. However, it is easy to grant another user permission to modify and delete your jobs using the qsub option --run_users. For example, "qsub -t 10 -n 512 --run_users smith:jones myprogram.exe" will allow both Smith and Jones access to the job. This option can be used with any jobs, including those in a reservation. See 'Running With a Group of Users': http://www.alcf.anl.gov/resource-guides/queuing#Running_With_a_Group_of_Users for more information.
