Cluster Status:

Introduction:

There are 23 nodes for running production jobs (both non-caf and caf style). These are "node1" through "node23". For non-caf use, connect to these via ssh from hexfm1.rutgers.edu. Use the cafgui for caf jobs.

hexfs1.rutgers.edu is used for import/export of data.

hexcaf.rutgers.edu is used as the head node for CAF-RU.

Hexfm1 has 2GB of memory, all other nodes have 1GB of memory. Hexfm1, hexfs1, hexcaf, and node2 through node7 have dual 1GHz Pentim III cpu's. Nodes 8 - 15 have dual 1.5 GHz AMD cpu's. Others have dual 2.0 GHz AMD cpu's.

Data disks total about 5 TB with 3.3 TB managed by the Disk Inventory Manager (DIM) and the rest in scratch disk (or static data disk) /scr1 through /scr7.

There are two tape drives on hexfm1:

• DLT4000 drive is /dev/nst0 and /dev/st0.
• AIT-2 drive is /dev/nst1 and /dev/st1.

Data in farm:

• List of datasets and filesets from the local DFCatalogs, updated frequently by a cron job. Also list of datasets copied to Fermilab.
• Datasets status (Zongru)
• Users may insert .txt files in /cdf/data00/DATA_INFO/ in order to give quick descriptions of data imported or generated at Rutgers.
• Filesets in the DIM (stage list command)
• Datasets in the DIM (static and cached/nonstatic filesets counted separately)
• Status of filesets in RU datasets (on disk, on tape, etc)
• Listings of RU archive tapes

Monitoring links:

• An updating node status window is available.
• Inter-node network traffic.
• CPU utilization: recent long-term
