Computing Resources Within CSS

This is an overview of the computing resources available within CSS that I know about, as of October 26, 2010. It doesn't include things like personal workstations. I have been collecting usage statistics for all the linux systems for the past few months; I just don't have a good way of displaying them yet.

Linux

All linux systems are running Red Hat Enterprise 5.5, unless otherwise noted.

Linux Lab

The Linux lab in UW1-320 has 15 desktops and 8 1U rack-mounted systems. The network is 100mbit, although the rack-mounted systems are connected to each other via a gigabit switch. The switch is connected to a 100mbit uplink, though. I'm hoping to get all the ports upgraded to gigabit.

Desktops

uw1-320-01.uwb.edu through uw1-320-15.uwb.edu. These are generally available, although as lab machines they are subject to irregular load, and students may reboot or disconnect them without warning. I'm trying to cut down on that kind of thing. I believe uw1-320-00.uwb.edu–the podium machine–shares this configuration, although I haven't confirmed that.

  • Intel(R) Core(TM)2 CPU 6400 @ 2.13GHz (dual-core)
  • 1GB RAM
  • Around 30GB free disk
  • Warranty expired: 9/7/2010

Rack-mounted

uwb1-320-16.uwb.edu through uwb1-320-23.uwb.edu. There used to be 16 of these, but recently half of them had their CPUs and RAM removed and given to the other half. These are also available via the round-robin DNS alias uw1-320-lab.uwb.edu. These should be available 24/7 except during regular maintenance windows. There's no service guarantee, though, as the hardware is out of warranty. Also, these may be more heavily loaded than 1-15, since they're part of the lab alias.

  • Two Dual-Core AMD Opteron™ Processor 2210 @ 1.8GHz
  • 2GB RAM
  • Around 30GB free disk
  • Warranty expired: 9/10/2010

Grad/Research Lab

Located in UW1-302. This is a hodgepodge of machines, mostly purchased on research grants but some for the graduate program. I believe it is all 100mbit. With less student access to this lab, there's less likelihood of machines being randomly rebooted or unplugged from the network. However, these machines may be more heavily loaded than others, as they're used for research.

hercules.uwb.edu

Munehiro uses this as the head node for his wireless temperature sensors.

  • Dual Intel(R) Xeon(R) CPU E5520 @ 2.27GHz (each quad-core with hyperthreading)
  • 6GB RAM
  • Dual Nvidia Quadro NVS 295 graphics cards
  • Around 120GB free disk
  • Purchased with graduate program funds, I believe
  • Warranty until 3/12/2014

hydra.uwb.edu

Mike's machine for research using CUDA.

medusa.uwb.edu

The head node of the mnode cluster, I think. I'm not entirely sure what runs on these. I'm pretty sure it's from a research grant of Munehiro's, though.

  • Intel(R) Xeon(TM) CPU 1400MHz, either dual-cpu or dual-core. I think dual-cpu.
  • 512MB RAM
  • Around 20GB free disk
  • Red Hat Enterprise WS 4.8
  • Warranty expired: 8/30/2004

mnode0.uwb.edu through mnode7.uwb.edu

  • Intel(R) Xeon(TM) CPU 2.80GHz (single core)
  • 512MB RAM
  • around 10GB free disk
  • RHEL WS 4.8
  • Warranty expired: 5/31/2006

phoebe.uwb.edu

I have no idea what the history or use of this machine is.

  • Intel(R) Pentium(R) D CPU 2.80GHz (dual core or dual cpu)
  • 1GB RAM
  • around 20GB free disk
  • RHEL WS 4.8
  • Warranty expired 1/22/2009

io.uwb.edu

I have no idea what the history or use of this machine is.

  • Intel(R) Xeon(TM) CPU 2.00GHz (dual-core or dual-cpu)
  • RHEL WS 3.9
  • 1GB RAM
  • Around 20GB free disk
  • Warranty expired: 3/21/2006

tarvos.uwb.edu

I have no idea what the history or use of this machine is.

  • Intel(R) Pentium(R) D CPU 2.80GHz (dual-core or dual-cpu)
  • 1GB RAM
  • Around 30GB free disk
  • RHEL WS 4.8
  • Warranty expired: 1/22/2009

priam.uwb.edu

I have no idea what the history or use of this machine is, and I'm only half-sure that it's located in this lab. I should double-check.

  • Same specs as tarvos.uwb.edu.

aglaea.uwb.edu

It has only recently come to my attention that this machine exists. I will see if I can break in and determine its configuration, then bring it up to date, since it won't have been getting any updates for the last year or so.

Data center

The UWB IT data center is located on the ground floor of UW1.

metis.uwb.edu

Metis is the authentication/authorization/file server for most of the CSS linux systems. It is not general access, and shouldn't be used for interactive login unless necessary.

  • Dual Intel(R) Xeon(R) CPU 5140 @ 2.33GHz (each dual-core)
  • 4GB RAM
  • Around 95GB free disk (5x 146GB drives total, probably configured in RAID)
  • RHEL 4.8
  • Warranty until 1/24/2011

mnode8.uwb.edu through mnode31.uwb.edu

  • Warranty expired 2/18/2008
  • Intel(R) Xeon(TM) CPU 3.20GHz (1-core, hyperthreading)
  • 512MB RAM
  • Around 18GB free disk (36GB total)
  • RHEL 4.8
  • Warranty expired: 2/18/2008

Mnodes 8,9, 29 and 30 are currently unavailable.

Windows

Windows lab machines use a common image maintained by IT. At this time it is based on Windows XP. I am hopeful that it will be based on Windows 7 by mid-2011. There is no remote desktop access to these machines; users must be physically present. It may be possible to install distributed computing clients, however.

Windows Lab

The Windows lab in UW1-310, and I believe it is wired with gigabit ethernet. There are currently 14 Dell Precision T1500 desktops and 2 Dell Precision T3500 workstations.

Desktop

  • Standard IT-provided Windows XP image
  • Intel(R) Core(TM) i7 CPU 860 @ 2.80GHz (quad core with hyperthreading)
  • 3GB RAM
  • Around 200GB free disk

Workstation

  • Standard IT-provided Windows XP image
  • Intel(R) Xeon(R) CPU W3520 @ 2.67GH (quad core with hyperthreading)
  • 3GB RAM
  • Around 120GB free disk

Embedded Lab

I haven't done a survey of the embedded systems lab in UW1-321(?). I do know the machines are old and need replacing, and at least one of them has failed, but beyond that I can't say much other than that they run the XP image.

Virtual Infrastructure at UWB

IT maintains a VMWare VSphere virtual computing infrastructure that may be available to use at a nominal charge. Details haven't been hammered out on this yet.

Virtual Infrastructure in the Cloud

These aren't anything CSS has a special deal with; they're just programs I know about, in the sense that I've read the pages linked to.

Amazon provides grants for educators to use their cloud computing infrastructure:

Microsoft also has some kind of academic pilot program for their Azure environment:

Google App Engine doesn't seem to have an academic discount program, but their base service includes a fair amount of usage free per day:
