“Green Giant” the I-cluster?

So the 3g iPhone is out, and a _lot_ of 1st gen iPhone people are looking to grab this new phone as a replacement due to the new features, 3g, gps etc …

That leaves a _LOT_ of 1st gen iPhones that potentially are going to end up on your local dump (landfill) …

Further to the “Green Giant” beowulf cluster project, with the 1st gen iPhone having been cracked open for homebrew multiple times (Hackaday search for Iphone), why not try to re-cycle the 1st gen iPhones into this project as cluster nodes?

I am now looking at places like freecycle to see if I can get hold of any 1st gen’s to do development on … time will tell

But one of the features I have planned should I be able to get hold of a 1st gen or two is using the accelerometer to control the nodes online / offline status …

Anyway all concept and dreams unless one appears.

Green Giant - Hardware Estimates

Ok so I have begun to work out the cost implications of doing this …

On the upshot the concept I have in mind will allow for nodes to be added dynamically.

Anyway onto the “beancounting”

GA-G33M-DSR2 £65.56 (ebuyer)
Corsair 4GB DDR2(800mhz) £65.35 x 2 (£130.7)
Intel core 2 quad Q6600 Energy Efficent 95w 2.4GZ 8mb L2 (4mb per core pair) £126.99

Total: £323.25

—-

Example config:

5 Nodes
20 Cpu cores
48 GHZ
40GB Ram
150 Gflops (estimated)

£1616.25 Total
£33.67 / Ghz
£10.78/Gflop/s

—–

Quite a considerable “chunk” of change, anyone any ideas as to cheaper suppliers? my Prices are based on the ebuyer.co.uk costs at the time of writing.

For US readers £1616.25 @ £1:$1.9432 = $3140.697 total = $628.14 / node

Update based on my previous spec here

“Not draw more than a total 30w / GHZ under load (Bringing the 4 node total to just 120w)”

Based on the current estimated 400w @ 48GHZ = 8.33w / GHZ (Well under target) …

We shall see what the actuall power consumption is once I find an alternate supplier.

dbStat Changes Name to “Adimpleo”

“adimpleo” Latin for “to perform”, seemed a fitting name for dbStat. dbStat is currently being re-worked to include the use of rrdtool among other features, “adimpleo” is to be geared towards providing an “under the hood” view of LAMP based web applications. Expect screenshots soon.

Green Giant - eBay Con Artists Part 3

Well lets start with the good news, the compact flash memory has arrived …

Now for the bad, following on from my last blog regarding this here the package arrived allright, but with all of £0.52 worth of royal mail postage, not recorded, not special delivery, no insurance, nothing £16 charge for £0.52 in postage … even with the packaging this no where near amounts to £16 worth of postage.

This is an utter JOKE, I am processing the photos for upload, the originals ar 5MP so a little to big for a blog ;-)

I have put in a complaint with ebay, citing this as using their postage system to “Extort” additional money.

Hopefully they will also see it this way, that does mean I can not “name and shame” at the moment, as it will not help my case.

Check back soon for the photos of the “£16” postage and packing …

4 x 1gb CF £3.96, POstage and packing £16, warm glowy I\'ve been conned feeling PRICELESS

a £16 stamp, take a good look it\'s rare

Wow Bubblewrap is SO EXPENSIVE!
