MINOS Computing Information

Summary of MINOS (and NOνA) Computers at Minnesota

Most machines have data areas which are accessible from all machines as /data/[machine] (e.g. /data/mnhep19), except that minos-server's data area is /data/minos. Hostnames end with ".spa.umn.edu". Locations are in Tate.

Name Location RAM CPU type CPUs UPS Hard Arch Soft Arch SL ver MBench "; $filelist=dirarray("./", ".$owner.spec"); if($donat) natsort($filelist); else sort($filelist); for($i = 0; $i < count($filelist); $i++) { $parts = explode(".", $filelist[$i]); $verfile = "./$parts[0].ver"; $htmlfile = "./$parts[0].$owner.spec"; $archfile = "./$parts[0].arch"; $phyarchfile = "./$parts[0].phyarch"; $upsfile = "./$parts[0].ups"; $benchfile = "./$parts[0].bench"; include($htmlfile); print(""); if(file_exists($upsfile)) include($upsfile); print(""); if(file_exists($phyarchfile)) include($phyarchfile); print(""); if(file_exists($archfile)) include($archfile); print(""); if(file_exists($verfile)) include($verfile); print(""); if(file_exists($benchfile)) include($benchfile); print(""); } print(""); } dotable("neutrino"); ?>

Most columns are set by hand and were up-to-date on 2010 01 29. "Soft Arch" and "SL ver" are automatically updated nightly. A few bear some explanation:

Data Disk Space (last updated "); echo date ("F d Y H:i", filemtime("NeutrinoSpace.html")); print(")"); print("

include("NeutrinoSpace.html");
print("
"); ?> Available Minossoft Distributions (last updated "); echo date ("F d Y H:i", filemtime("list_minos.html")); print(")"); print("
");
include("list_minos.html");
print("

Other Departmental Computers

Starting here, the page is not kept up to date much at all. (As of 2010 01 29.)

These computers are not owned by MINOS (or even NOνA). They belong to the condor group '"mnhep"' (the name includes the quotes!) and are owned by someone in the high energy group. They can be used, at least sometimes, for MINOS work. You should consider running your condor jobs with nice_user if you run here, but it is not required. This list may be out of date. Check 'condor_status'. Yes, not all computers named "mnhep" are in this group.

Out of date. (As of 2010 01 29.)

These computers are owned by the Cleo and/or Bes III groups. They constitute the condor group '"cleofarm"', and can be used sometimes, with explicit permission from the Cleo/Bes III group, for MINOS work. This list may be out of date. Check 'condor_status'.

Out of date. (As of 2010 01 29.)

These are various desktops around the department and belong to the condorgroup '"physlin"'. They can also be used for MINOS work. You should consider running your condor jobs with nice_user if you run here, but it is not required. This list may be out of date. Check 'condor_status'.

physlin computers are configured by default (2009 06 24) to never run condor jobs on their first processor unless they have only one. This can be overridden by the condor user by setting the condor variable "HappyToBeEvicted" to "True".
