Monolith 2015 03

Updated 2015-03-13

I finally received the order for the last 11-cpu boards from r0ck.me. That didn't work out well I ended up having to place a paypal claim to get them to send them to me. What a shame to end our relationship on such a sour note.

I don't think I will purchase anything from them again. I placed the order on Feb 13 - they got paid quickly but they didn't seem to feel the need to ship my property to me very quickly. Enough said about that matter. They don't exist for me any longer.

I mounted the 11 cpu units on the threaded rods with spaces and cut (2) pieces of acrylic plastic for the end-pieces.

I have the new tier held in the rack by a pair of vise-grip pliers until I can drill new holes and secure with screws.

I also built the wiring harness and soldered it into the main +5VDC harness.

I had (6) 4GB Adata cards and (2) Airlink 101 USB wifi adapters so I configured node 55 and node 56 today.

I built new boot disks (micro sd cards) for nodes 57-60 as well.

I have more micro sd cards and more USB wifi adapters on order. Enough to complete the Cubical Monolith Project.

I tested all the new cpu units and everything seems perfect. I was in a hurry to test them before I close the paypal case against the vendor.

If you notice in earlier journal entries I installed the bottom tier before the middle so I could get a permanent installation of the master node. Today I moved those bottom tier Airlink adapters and cards up into the new middle tier and will repopulate the bottom tier with new cards and wifi adapters. Those cpu units have been well tested.

If I have time this weekend I will mount the middle tier permanently eliminating the need for the vise-grips. As any good engineer knows vise-grips are miracle tools.

I finally mounted the last tier permanently.

I recieved the remainder of the USB wifi adapters and some more micro sd cards. I am completing loading the operating systems on the remainder of the nodes and bringing them up one by one.

Using 4GB micro sd cards for each node.

DONE

Once I have booted the node for the first time I perform several more tasks.

1. sudo apt-get update
2. aptitude install cfengine2
3. cd /var/lib/cfengine2/inputs;scp root@master:/master/tmp/cfengine.tar .;tar xvf cfengine.tar;cfagent -q (the cfengine.tar has the boilerplate cfengine files I need to get cfengine bootstrapped.)

4. pip install mpi4py
5. pip install numpy

As I have noted elsewhere in these journals the high wall clock time is because we're using wifi. When I was using ethernet switches it was very low.

The entire 66-cpu array is using 3.02A @ 110VAC (input) during a full-scale run of John The Ripper on an 180K hash password file. I will let it run overnight just to do a burn in and then probably turn it off. I don't need another $400 power bill.

Internally on the DC side it's much more of course.
