Computer Cluster

---

Through support among several faculty members (Hart, Chassignet, Reasor, Erlebacher, Zou, Ruscher), our research group has access to a Linux Beowulf cluster designed by Hart, with gigabit internal networking.

You can view the status of the machines in the cluster at http://moe.met.fsu.edu/machines. You can view the status of the UPSs in the cluster at http://moe.met.fsu.edu/cgi-bin/multimon.cgi.

Hardware:

• 36 nodes
• 130 cpus

Total memory: 370GB

Total RAIDed disk space: 100TB

Total unraided disk space: 20TB

Tape drives: 100GB LTO1 on moe; 400GB LTO3 on otto

Software installed:

• OS: CentOS 5.6
• Portland Group Compilers 5.2, 6.0, 7.2, 8.0, 9.0
• Intel Fortran and C Compilers 10.1.021; 32 and 64bit
• GrADS 1.7-2.0alpha9
• Matlab 7.6.0.324: R2008a
• McIDAS-V
• Garp/GEMPAK 5.11.1
• IDL 8.0
• Vis5D
• R 2.10.0
• mpich1 [in /opt/local/mpich-pgiXYZ and /opt/local/mpich-ifort]
• mpich2 [in /opt/local/mpich2-pgiXYZ-64 and /opt/local/mpich2-ifort64]
• wgrib, wgrib2, gribw, cnvgrib, grib2ctl.pl, g2ctl, NCAR spherical harmonic converters
• GoogleEarth v5
• NCAR Graphics & NCL
• WDSS2
• Solo
• Slicer
• netCDF
• FFTW
• Many other smaller ones.

Usage Protocol:

• Priority on parallelized jobs is always given to users working on theses. This cannot be stressed enough.
• Absolutely no browsing of clearly questionable web pages. This also cannot be stressed enough.
• Abuse of the cluster will lead to job termination and locking of the account.
• Machines with console users should never be used for parallelized jobs without asking the console user first.
• Routine jobs (crons) should always be approved before use.
• For security, you can only ssh or sftp into the cluster through huey or metlab.
• Accounts with weak passwords will be locked.
• Your password should be different from other accounts you have.
• If you have a question on how to do something, or whether you can do something, ASK!
• The only public RAID5 or RAID6 partitions on the cluster are:
  • /home
  • /opt
  • /moe/GRIB
  • /moe/r0
  • /barney/r0
  • /frink/r0
  • /itchy/r0
  • /otto/r0
  • /scorpio/r0
  • /apu/r0
  • /ned/r0
  • /kang/r0
  • /kodos/r0
  • /dvrw/r0
  • /uter/r0
  • /uter/r1
  All other partitions are not redundant and have a much higher chance of data loss. Thus, back up your own files if you are using partitions other than those listed above.

Ownership (does not include implied sysadmin by Hart):

• Hart: 80%
• Chassignet: 9%
• Reasor: 6%
• Erlebacher: 1%
• Zou: 1%
• Ellingson: 1%
• Ruscher: 1%
• Winterbottom:1%
