COMPUTING ENVIRONMENT

There are currently six different brands of computers at SEP, with varying functionality:

• HDS Xterm (machine names: fujiyama, avila, and ciuc)
  • You can't login into these machines. They are directly connected to the HPs with each Xterm assigned a primary HP to connect with.
  • They do not have the same windows environment as all other platforms so part of the setup section below is invalid. To open a window on another machine, type xon machinename.
• SUN (oas, taal, pele, zarand, and etna)
  • Oas serves as:
    • the server for the SUNs, which is to say it holds the /usr/local/disk, which contains files that are platform specific;
    • the SUN which holds /usr/pubsw, the location of numerous programs available through afs;
    • our ypmaster;
    • our main platform to run Promax and Focus;
    • our mail server, along with etna and taal;
    • our host for the home directories;
    • one of the primary hosts for personal devices.
  • Pele (aliased sepwww, sepftp, taishan) is our web server.
  • Zarand is used for testing CDs.
  • The SUNs are also a good place to check for programs and man pages that you can't find on other machines. For years the SUNs were our primary platform and therefore things were installed most completely on them; this is no longer the case.
• CM-5 (Connection Machine) (vesuvio is actually this is the SUN front-end)
  • To use the CM, you need to program in CM-Fortran, a dialect similar to High Performance Fortran and Fortran 90.
  • The status of the CM at SEP is questionable so large time investments learning to code for CM might not be worthwhile.
• PC running Linux (koko and fuego)
  • Koko is the server for the Linux machines.
  • These computers are very similar to the ones all SEP students will be having at home.
  • GNU software comes pre-installed on these machines so they are going to be the most robust when running Emacs, gcc, etc.
• Hewlett Packard (spur, okmok, sthelens, rainier, hakone, picacho, and pinatubo)
  • Spur
    • serves as then home of many of the personal drives, and the global source directories;
    • s our fastest single processor (135 Mhz);
    • runs afs, files located in /usr/pubsw; and
    • is one of our top graphics machines.
• Silicon Graphics (santorin)
  • Santorin:
    • is a 16-node Power Challenge super computer;
    • is one of our better graphics workstations;
    • is co-owned with Petroleum Engineering Department; and
    • does not have the complete SEP environment (for example Emacs is not installed) to discourage wasting valuable compute time.
  • Make sure to read and follow the rules().
