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 4.7 (Fermi).
Condor batch submission node

|minos26||reserved (unavailable for general use)||mindata||32bit kernel access, nightly build
This node is used to build base releases -- 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).
