Taking Stock of Our First Year

2016 has been a busy initial year for High End Compute consultancy, and I would like to pass my thanks to each of you for your support. As I look forward to 2017, and the opportunities that it brings to work with several of you, I realise that I have capacity to do further work and would welcome discussing potential work or collaborations (full contact details in signature).

The key services that High End Compute provide are:

Raspberry Pi Bramble - quick setup

Over the winter nights I've been working to set up a straightforward procedure for anybody to build a cluster out of Raspberry Pi boards, the PiHub, a few USB (power) leads, a cheap un-managed LAN box and a couple of LAN cables. By using MPI for Python via the Rasbian python-mpi4py package it is now within reach for us all to do both distributed computing (using MPI) between RPis as well as threaded (using OpenMP) on the 4 cores of the Pi 2.

How Green is Your Jetson?

Very much a work in progress

To determine how (power) efficient our new Jetson is for numerical computations, we shall consider a few things, one at a time:

  1. A single core of the ARM Cortex CPU
  2. The low power core of the Cortex
  3. The NVIDIA GPU
  4. All the CPU+GPU cores on the Jetson

As well as what to measure, there are questions over how to measure:

Future of programming accelerators is Open, wide open

The hardware changes on the horizon of 2016 may already be fairly well known but what about the shifting sands of software?
The rumour from SuperComputing is of Intel quietly sounding out the customer view of pulling OpenCL support from its Xeon Phi cards.

Why Intel would want to do this? Without insider knowledge we cannot say for sure. The answer probably lies in either a CBA regarding continued support for OpenCL on XPhi or in expected popularity growth of alternatives.
