.. and a few pictures post Hawaii. Most of the exterior walls on the third floor are now done. Interior walls next, then some shear wall work, then the deck, then the two story tall great room walls.

A few pictures pre Hawaii.. Third floor is making progress.
Nano
This is kind of a neat little development board. Raspberry Pi sized, quad-core ARM plus 128 NVidia Maxwell CUDA cores. 472 GFlops in a very small package, perfect for machine learning camera image recognition. I’m thinking about putting one of these with every camera in my new house so I can have continuous object recognition feeding into a central AI.
Processor
I have been noodling around the idea of doing my own processor for my supercomputer. I’d like to play around with some old school SIMD PE architectures, and those design works well within an FPGA implementation. Curious if any of my nerd/processor architecture friends would comment on a selective execution idea I am considering.

A classical problem in SIMD machines is how to handle partial execution, where you want only some processors in the cluster to execute certain instructions. The method I am proposing is a combination of an old school vector mask combined with RISC style register/register instruction set.

3rd Floor Joist are starting to materialize. Once those are finished the rear deck will get installed, which will make building of the great room 2 story walls much easier. It will be cool to see the third floor built.
CanPi
For my fellow nerd friends – I wrote up a quick short note describing the operation of my CAN-PI datalogging hardware board. I would love to hear some comments/suggestions/criticisms/race conditions I didn’t think of/etc. It does contain a quick walk through of the critical parts of the interrupt handlers.

Interior walls go so much quicker. The floor joists for the 3rd floor were delivered today, so as soon as they get the deck joists installed they can start on the next floor.
I did an overlay merge with one of the picture and the floor plan, and it looks like they built what we designed.

A few more snow days last week plus some really cold and windy days make for hard work, but more walls are coming into form! The shop is mostly complete in terms of framing, with the exception of the small bathroom I added. That will get framed a bit later. The middle level outside walls are getting built now, and the rear deck framing will happen next before doing the two story main level walls.
The windows have also arrived, but are in storage. As soon as we get framing done we will get the windows and the roof on so we can seal things up.
The Glulams for the deck were also delivered. I didn’t notice in the plan that all of the ‘floor joists’ under the deck are 3.5″ x 13.5″ x 22′ glulams. 40 of them. One glulam of that size at 22′ long should support around 320lb/linear foot or a total load of 7000lbs. Given there are 40 of them that is 280,000 lbs of load, which seems like a lot, even with the covered portion. Well engineered I think.
