MINOS Cluster Node Assignments
The MINOS Linux cluster is available to MINOS collaborators for MINOS computing efforts. At this time we are not running load balancing software for interactive logins and thus rely on users to distribute themselves amongst the machines (Ganglia can help here). Because the local scratch disks are not cross-mounted interactive users often find themselves repeatedly using the same machine. This can be avoided by the migration to the /minos/scratch network storage disk space.
This page serves as a central place to record the nodes that have a predefined purpose as well as those that individual users favor.
| A listing on this page generally does NOT grant any license of priority, exclusivity or any other special privileges. This page is for the purpose of facilitating the avoidance of conflict and to enhance an uniform distribution of demand on MINOS resources. |
| The exception to the above are machines/processes with this background color which are deemed important services. These machines should be generally avoided if possible so as not to interfere with these important services. |
Unless otherwise stated all nodes are running Scientific Linux 4.4 (Fermi).

| minos02 | RETIRED | system failed 2009 06 22 | |
| minos03 | msanchez | general use | |
| minos04 | ntagg | general use | |
| minos05 | bv | BDP (beam data recording) backup, not much CPU but data may get dropped if totally starved. | |
| minos06 | tjyang | general use | |
| minos07 | XROOTD server | gmieg | xrootd server prototyping (may use lots of disk) |
| (avva) | nightly offline monitoring cron jobs: 3 processes that start at midnight and run for several (up to 5) hours. | ||
| minos08 | rustem | general use | |
| minos09 | shanahan | general use | |
| buckley | general use | ||
| minos10 | brebel | general use | |
| plunk | general use | ||
| minos11 | SLF3 Build Node |
nightly build |
This node should be used to compile/link code in order that
executables be usable on both SLF3 and SLF4 nodes.
Not for running long jobs.
This node is also used to build base release -- this means that heavy use at night could delay completion of nightly "development" build. A complete clean build is done every Sunday night (10pm - ~4am FNAL-time). |
