MAY UPDATE II
Yesterday (3/22/13) was the Friday before break. It had the feeling of a celebration like the day before XMas break. I suppose that's because we haven't had a break since then.
Not only did Hurricane Sandy close the school for 10 days and condemn the Math building, but it cancelled Midterm Week and February Break too! Thanx a lot, Sandy....

1 from mpi4py import MPI
3 rank = MPI.COMM_WORLD.Get_rank()
4 size = MPI.COMM_WORLD.Get_size()
5 name = MPI.Get_processor_name()
7 print ("Hello, World! "
8 "I am process %d of %d on %s" %
9 (rank, size, name))
We saved this text in the file helloMPI.py in the pelicanHPC home dir. Then, from a shell in the home dirm we executed this code by:
We downloaded the new ISO with mpi4py from http://www.pelicanhpc.org and followed this tutorial: http://pareto.uab.es/mcreel/PelicanHPC/Tutorial/PelicanTutorial.html and this one too: http://pareto.uab.es/mcreel/PelicanHPC/pelicanhpc.pdf and http://pelicanhpc.788819.n4.nabble.com/How-can-i-find-out-which-are-processes-are-being-sent-to-which-node-td3034955.html and http://www.linuxpromagazine.com/Issues/2009/103/CLUTTER-TO-CLUSTER

UPDATE: mpi4py was left out of the current pelicanHPC by mistake! No wonder mpi4py didn't work! Look here:

Here's the steps we followed for a minimal install of the Student Stations (64bit Athlons):
Reboot each Linux box with the current CD. Answer some basic questions about time zone, userid, passwd, no login on bootup, etc.
Reboot each Linux box without the CD. Make sure to configure the gigE cards and proxy server:
Configure System Settings as desired (unit circle trig calculator background, no screensaver, etc).
We had to switch Software Sources in the Ubuntu Software Center (edit/source) to Main before this would work:
sudo apt-get update
sudo apt-get upgrade
Now, we could use the Ubuntu Software Center to install WINE.
I copied my VTI83 and VTI89 directories from my memory stick to the Desktop. Then, after editing preferences to have VTI open with WINE, I configured each calculator.
I will edit my /etc/crontabs tomorrow....
We haven't decided what else we may have to install (local SAGE server, JRE, openSSH, openMPI,etc). We'll have to think about that! Here's some info on install fests from prior years:
Ubuntu Release History
4.10 Warty Warthog (mammal)
5.04 Hoary Hedgehog (mammal)
5.10 Breezy Badger (mammal)
6.06 Dapper Drake (bird)
6.10 Edgy Eft (amphibian)
7.04 Feisty Faun (mammal)
7.10 Gutsy Gibbon (mammal)
8.04 Hardy Heron (bird)
8.10 Intrepid Ibex (mammal)
9.04 Jaunty Jackalope (mythical beast)
9.10 Karmic Koala (mammal)
10.04 Lucid Lynx (mammal)
10.10 Maverick Meerkat (mammal)
11.04 Natty Narwahl (mammal)
11.10 Oneiric Ocelot (mammal)
12.04 Precise Pangolin (mammal)
12.10 Quantal Quetzal (bird) release: 10/18
Guardian, our ssh server, is running 10.04 32bit. Guardian has a dualcore 32bit intel Xeon processor with 2GB RAM and a 512GB RAID drive.
Caprica, our ftp server, is running 10.04 32bit. Caprica has a dualcore 32bit intel Xeon processor with 2GB RAM and a 512GB RAID drive.
Shadowfax, our teacher station, is running 11.10 32bit. Shadowfax has a dualcore 64bit amd Athlon processor with 2GB RAM and a 256GB hdd. We use a 32bit OS here as SmartNotebook doesn't run on 64bit....
Alpha-Omega, our student stations, are running 11.04 64bit. These Linux boxes, like Shadowfax, have dualcore 64bit amd Athlon processors with 2GB RAM and a 256GB hdd.
We are only upgrading Alpha-Omega to 12.04 (or 12.10 if it's available when we upgrade in a couple of weeks). We are also waiting for a hardware upgrade for Alpha-Omega to amd quadcore Phenoms!
(1) Wreath of the Unknown Server:
We visited our first ssh server, Colossus, which is still in the switch room though dormant. I set it up for the first time in 1995 running Slackware Linux. Colossus ran for 12 years straight, 24x7 never having to shut down, reboot or even have anything re-installed! Colossus would not die. We finally just replaced Colossus with a dual-core Intel Xeon box complete with a RAID drive running 1TB. Old Linux boxes never die, they just fade away...
(2) Display Case Unveiled:
We took down a ton of fractal prints and ray tracings from Room 429 to the 2 cases on the 1st floor near the art wing. We decorated both cases as best we could and left before anyone saw us. Must have been gremlins.
(3) Recruiting 2012:
We decided that we did not have a good pool of candidates to recruit more CIS(theta) members for this year's Geek Squad, so we tabled that topic.
(4) Planing 2012:
Next meeting would have been 9/28 but that's Yum Kipur. So, we have to wait another 2 weeks after that for 10/10 at which point Ubuntu Precise Pangolin 64bit release 12.10 Desktop Edition should be available for a mini install fest. After that, we may use bootable cluster Linux CD distros to learn MPI.
