UO Information Services Intensive-Computation Resources

Overview

Six dual processor 64bit AMD Opteron workstations running Linux have been built for the purpose of supplementing the computing resources available to users with uoregon.edu accounts. All users with access to shell.uoregon.edu can use these systems. uoregon.edu home directories are accessible here, as is the /scratch directory from shell (previously darkwing) mounted as /darkwing-scratch. A local scratch directory mounted as /scratch is available for requirements that exceed the size of your uoregon.edu home directory. The local scratch directory is shared between all six systems and is 735GB in size compared to shell's 80GB scratch dir.

The current host compliment is:

acad-cl0         nfs server (no users)   2ghz Intel xeon 1GB ram 800GB disk
acad-cl1	 compute host	         2 x AMD Opteron 244 4GB ram 80GB local disk	   
acad-cl2	 compute host	         2 x AMD Opteron 244 4GB ram 80GB local disk
acad-cl3	 compute host            2 x AMD Opteron 240 2GB ram 80GB local disk
acad-cl4	 compute host            2 x AMD Opteron 240 4GB ram 80GB local disk
acad-cl5         compute host            2 x AMD Opteron 250 4GB ram 160GB local disk
acad-cl6	 compute host	         2 x AMD Opteron 250 4GB ram 160GB local disk

Account Creation

You no longer need to request an account - all users with access to shell.uoregon.edu can login to the cluster with the same username and password.


Accessing the Cluster

Access to the cluster is available principally using the ssh protocol. A brief overview on using ssh on Windows and MacOS is available here. The hostnames and ip addresses of the systems currently are as follows:

     acad-cl1         128.223.162.81
     acad-cl2	      128.223.162.82
     acad-cl3	      128.223.162.83
     acad-cl4	      128.223.162.84
     acad-cl5	      128.223.162.85
     acad-cl6	      128.223.162.86

File-systems available for user storage are laid out on each system as follows:
     /home1 - uoregon.edu home filesystems. Your home-directory will be in the
     /home2   same location as on darkwing Be mindful that default quotas on 
     /home3   the home filesystems are typically 1 GB and things placed in your
     /home4   home-directory here will affect your quota on shell and other
     /home5   hosts.
     /home6
     /home11
     /home12
     /home13
     /home14
     /home15
     /home16
     
     /scratch-darkwing - The scratch disk on shell (previously darkwing). Available
                         for anyone to use.  Files unused for more than a month will
                         be expunged as is current policy. Files placed here are
                         accessible on shell. Space available there is 80GB.
  
     /scratch - Cluster-local scratch disk. No expiration date for files placed here. 
                Filesystem should not be presumed to be backed-up at any given time.

     /tmp - Local to each node. Files placed here should be of a temporary nature only.
            The temp directory will be expunged between rebootes which are expected to
	    be fairly infrequent. Space available is 18GB per node for acad-cl1 through 
            acad-cl4 and 36GB for acad-cl5 and acad-cl6.
