Welcome to the Phoenix Cluster wiki.

Cluster layout
Phoenix has a single head node and many compute nodes. The head node hosts the shared HOME directories, runs the job scheduling software, and provides login access to the cluster. The compute nodes provide scratch space for running jobs and execute the actual software submitted to the cluster. While your HOME directories are identical across all the nodes, scratch space (/scratch) is unique on each node. Home directories should primarily be used for job submission preparation and result storage. Using your HOME directory as scratch space for a job will slow your jobs and may slow the jobs of others or make the head node unstable.

Other guidelines and policies
Cluster usage rate
Use of the default and short queues on phoenix incur a charge of $0.007 per CPU hour. This means that a 2 core job that runs for 10 hours will be charged $0.14. These charges will be made to the group your account is associated with unless you define an alternative group and fund number at the time you submit your job using the charge argument with the built-in submission scripts.
Receiving email from the cluster
To receive email regarding your jobs (errors, etc) from the cluster scheduler, make a .forward file in your /home directory containing your email address, as so:
username@chem.wisc.edu

Using Phoenix in the classroom
Submit coursework-related jobs to the education queue. Any other types of jobs are prohibited. Jobs submitted to this queue are limited to a maximum of 6 cores and a run time of 90 minutes.
If you are taking a class that uses the cluster, your account is typically authorized to access the education queue when your instructor provides a class roster to clusteradmin@chem.wisc.edu. If instead your instructor directed you here without pre-authorizing your account, please email clusteradmin@chem.wisc.edu to request access to the education queue. Please include what class you are taking and who your instructor is.
