12/28   I have access to a large supply of psx, n64 and snes...besides
        games are there any good uses for these consoles?  Are there
        ways to use them for parallel computing or educational
        purposes? -scottyg
        \- see e.g. http://arrakis.ncsa.uiuc.edu/ps2/cluster.php
           i wonder if they were able to buy the hardware subsidized. --psb
        \_ got any spare saturns?  Want to sell one?  -aspo
           \_sure, go to http://www.squaredealonline.com -scottyg
            \_ 50 bucks???  That isn't so square.
               \_ Check ebay, Saturns are having a bit of a revival.  I'll
                  be putting mine up soon, with games, if you're
                  interested. -jrleek

2/19    I program a lot by sshing to a Linux cluster.  So I'm used to using
        Xemacs to code.  This works fine from a Linux or Windows workstation,
        but sometimes I have to use a Mac.  On Mac, the meta is usually
        bound to option, but that often doesn't work over ssh for some reason.
        This makes using emacs a real pain.  Any suggestions on how to fix it?

8/26    Amazon medium instances (3.75GB RAM): 0.160/hour = $1382/year
        Generic standard Linux VPS (4GB RAM): $480/year
        Amazon costs more (but does offer superior scaling options).
        \_ Amazon is $670 if you buy a year's usage up front (heavy util).
           Why is heavy util less expensive than light util?

1/4     I want to test how my servers behave during a disk failure and
        a RAID reconstruction so I want to simulate a hardware failure.
        How can I do this in Linux without having to physically pull
        a drive? These disks are behind a RAID card and run Linux. -ausman

7/21    Can I just use ifconfig to expand my netmask on a FreeBSD box?
        Are there any gotchas here? Linux forces me to restart my network
        to expand my netmask.
        \_ yes... and no, you don't have to restart your network on linux either
           \_ Rebooting is the Ubootntoo way!

5/5     Does anyone know how to do custom install of Ubuntu 10.04? I can't
        even boot it up to give me the menu to custom install and it
        keeps installing a bunch of crap I don't need. It's getting
        just as slow and bloated as Winblows install. Dear lord,
        I miss the old Ubuntu.

4/22    In Linux is there an easy way to rename the scripts in /etc/rc?.d ?
        For example I want to set all the /etc/rc?.d/S91apache to S100apache
        so that it'll run the ramdisk BEFORE going to apache.
        \_ Sure, just move them.
           \_ I mean is there a script that will rename all of them
              for me? Like: setrc apache2 0 0 1 1 1 1

8/29    There was once a CSUA web page which runs an SSH client for logging
        on to soda.  Does that page still exist?  Can someone remind me of the
        URL please?  Thx.
        \_ what do you mean? instruction on how to ssh into soda?
           \_ No I think he means the ssh applet, which, iirc, was an applet
              that implemented an ssh v1 client.  I think this page went away

The NCSA has constructed a PlayStation 2 Linux cluster as a test bench fo r scientific computation on "toy" hardware. The cluster consists of 65 c ompute nodes, 4 user login and development nodes, and 1 prototype node f or software installation tests. All the nodes run the Sony Linux distrib ution for PlayStation 2 The compute nodes fill a 24-inch rack; This distribution uses Linux 221 ported to the PlayStation's Emo tion Engine CPU, and is based on an earlier version of Red Hat Linux for PC's. The distribution includes development tools that you would expect ; libraries, editors, compilers and debuggers that you'd find in any Lin ux distribution. The kit also includes software tools that provide hooks into the PlayStation 2 specific hardware. Several other pieces of software have been built for the cluster that wer e not available from the distribution. We have built and installed pbs, maui, Argonne's mpi ch, and open-ssh. Since most any software that will build on a Linux mip s system will build on the PlayStation 2 Linux kit, any mips-compatible software with source code available can be run on the cluster. The operating system install on each machine was performed using a ramdis k image set up by Perry Melange. This image partitioned and formatted th e hard drive, and downloaded and uncompressed file system images, then r eset the boot configuration and rebooted. This was done to make sure occ asional differences would not exist between nodes, and lower the time ne eded for a complete re-install. Cluster Tests Members of the U of I Computer Science department have run tests across 6 4 nodes of the cluster. The tests used code running on just the core CPU , not the Vector Units, using the ethernet as the process interconnect. These test calculations did not demonstrate any more problems than any o ther new cluster. Network Configuration The Linux kit includes a module that attaches to the back that provides a 100baseT ethernet network interface. The PlayStations are networked tog ether through ethernet via two HP Procurve 2650 switches, roughly half t he cluster connected to each. The two switches are connected together at 1 GB/s, and to the firewall/fileserver at the same speed.
