So I’ve always wanted to roll my own home continuous integration (CI) server - I use Jenkins as my main CI at work (having used Atlassian’s Bamboo and the hideousness that is buildbot in the past), so I thought I may as well start there. I previously tried to get Jenkins running on my Raspberry Pi B+ - but the single core and general slowness of the device just meant it wasn’t feasible.

I’ve uploaded my slides with speaker notes for the Khronos/EuroLLVM talk I gave this week. Please check them out! WhySPIR-V

After reading “SIMD at Insomniac Games – How we do the shuffle” I realised I hadn’t done anything with my new Raspberry Pi 2 yet. First thing I decided was to try and figure out whether the NEON unit in it was any good, and so I choose a really simple example, calculating a ton of dot products on 4 element vectors, and wrote a bunch of different implementations to try and solve this.
