ACC's Computing Resources

This page summarizes ACC's centralized computing resources at CLASSE

If you need to contact someone for help, please see the Getting Help section.

Operating Systems and Architectures

On Linux, uname -m will tell you the architecture, and cat /etc/redhat-release will tell you the operating system.

Farm (172.16.)

Node name network connection function details
lnx1625
hps50-f1 port
NOT part of linux compute farm
has AMD CPUs which produce different results from Intel CPUs
edit
lnx1626
hps50-f1 port B23
part of linux compute farm
General purpose CESR build and processing machine
edit
lnx301-lnx305 and lnx313-lnx324
hps50-f1
part of linux compute farm
CESR members are allowed up to 2 interactive jobs on each of these machines. Please use the top program to make sure that no more than 2 CESR jobs are running. These machines are rather isolated from the lnx209 server, so linking and I/O intensive use of these machines is discouraged.

A number of other Linux nodes are available via the GridEngine batch queues for running production jobs.

CESR Private (192.168.1.)

The CESR Linux Control System Cluster

The CESR Linux Control System cluster provides clustered file systems and high-availability services using the Red Hat Cluster Suite. All members have connections to both the CESR Private and CESR BPM subnets. See CesrHAC for more information.

Linux Consoles

All linux consoles are running SL6.5. They auto-login to local user accounts and are only used as displays (windows appear from remote systems). They are also known as the "Grinnel replacement". In general, they are not used with a mouse or keyboard.

Software Versions

The primary Linux server and desktop operating system in use the in the lab is Scientific Linux (SL) which is assembled jointly by Fermilab and CERN as a standardized experimental environment. It is based on Red Hat Enterprise Linux. CLASSE currently deploys SL6.5 unless otherwise noted.

VMS/Linux Shared Disk

Backups

See BackupSchedule for a list of Linux, Dec-Alphas (Unix), VMS, and Solaris systems we currently backup.

See WindowsBackupSchedule for a list of the Windows systems we currently backup.
