We have a monitor, keyboard, mouse in the middle connected to two switches that allow connection to all the nodes
Pretty Impressive specs - although I forget the specifics specifications. I just know they have 16GB of Memory each, 4 Quad Core processors and some decent hard drives. At the bottom there is a UPS.
The problem with the UPS is that it had to be hardwired, which took a while for the electrician to come out and do, but then, we found out that the UPS only supports 8000W output, and the combined unit actually uses close to 15000W. You can see the problems there.
Now these pics were taken before the UPS was turned on.
This is the back of the unit. IT IS HOT!!
You'll notice quite adequate below floor cooling. We have two very powerful units blowing cold air under the floor and very few rooms have openings, this room being one of them.
The upper half...the head node is a 2950 and the other nodes are 1950s all from Dell of course.
The whole thing is networked on 1GB full duplex Ethernet, with Jumbo Frames enabled, usually.
That monitor is sweet, and very useful during install, but WAY TOO COLD for regular use.
The bottom half. We have this whole rack filled out except for one U, but that's ok.
Hopefully this will be the first of many research compute clusters.
Oh and its name, after some debate, because apparently Locutus of Borg was inappropriate, is CESAR200. Which as you might guess is an acronym for Computer Science Engineering Science and Arts Research Computer Cluster. Note that what we did was take the CC and just say each one was the roman number for 100 and made it 200. Sure, we might have done something else, but no one really complained so it works.
The exact cause or causes of CCD have not yet been determined. The results of two large surveys have identified more likely causal factors and eliminated some unlikely factors.Honey bee colony numbers in the U.S.A. have been in decline for decades. From 1947 to 2005 number of managed bee colonies has decreased by over 40%, from 5.9 million to 2.4 million. Beekeepers with CCD are reporting losses of 30% to 90%. Losses due to CCD are compounding an already serious shortage of bees for pollination while the demand for pollination services continues to increase for fruit, nut and, vegetable crops, especially almonds. Colony shortages were so critical that in 2005 honey bees were imported from outside the U.S. for the first time in 83 years since the passage of the Honeybee Act of 1922.
Basically, honey bees are dying and everyone from Universities to Häagen Dazs are trying to figure out why and fix it.
The reason I bring this up is because of some bizarre thing I noticed a while ago, which may or may not be related. Two massive trucks going South on US HWY 69 carrying, you guessed it, bees.
It may be hard to see, but these trucks were carrying bees, I could see them, but I was taking these pictures with my cell phone.
A slightly zoomed in picture
First, the sun is hot. Obviously, but what I mean is that it is hotter than you would imagine it to be in the morning if you don't usually walk outside for a mile at 7:30 in the morning.
Second, grass is very wet. I am wearing jeans and sneakers. My sneakers got soaked. My jeans got wet half way up my knees from grass that bearly rose above my ankle. Very annoying.
Third, traffic. Seriously, does everybody have to go to work the same time as I do? I had to wait 4 and a half minutes to cross the spur at the light.
This is my route, basically, although I cut through the parking lot of the business building rather than walk around it.

Side note, I am listening to Pandora right now, totally cool music. Check it out at Pandora.com, they basically let you listen to whatever you want for free. It is hard to concentrate because at this moment I am listening to Kiss, Rock and Roll all Nite, and I can't stop singing and it is really messing with my typing, good thing for backspace.
Ok, its done.
I have lots of pictures I want to post, however I need to get them off my microSD card first. So maybe this weekend I'll post some entries.
Oh, well besides that I also got Lego Indiana Jones for the PC. I love it, haven't played that much, but so far totally cool game.
It sort of looks like this one, although this one is actually leather, why anyone would want a leather coffee table I don't understand at all. Seriously.
Other than that I don't have too much to say, except NICE cliffhanger as it were regarding BSG. Revelations was a good episode and I am curious anyone knows what city that was supposed to represent. I've heard everything from New York to London to D.C., but frankly I suppose it is equally plausible to be a made up city.
