Docker and NVIDIA-docker on your workstation: Integration with your Desktop
Written on April 26, 2017 by Dr Donald KinghornI've been doing this series of posts about setting up Docker for your desktop system, so why not literally add containers to your desktop! The way we have Docker configured, containers are the same as other applications you run. In this post I'll show you how to add icons and menu items to launch containers.
TitanXp vs GTX1080Ti for Machine Learning
Written on April 14, 2017 by Dr Donald KinghornNVIDIA has released the Titan Xp which is an update to the Titan X Pascal (they both use the Pascal GPU core). They also recently released the GTX1080Ti which proved to be every bit as good at the Titan X Pascal but at a much lower price. The new Titan Xp does offer better performance and is currently their fastest GeForce card. How much faster? I decided to find out by running a large Deep Learning image classification job to see how it performs for GPU accelerated Machine Learning.

Intel Xeon E5 v4 Broadwell Buyers Guide (Parallel Performance)
Written on July 1, 2016 by Dr Donald KinghornIntel's Xeon E5 v4 processors are available and there are lots of them! The changes from the v3 Haswell are mostly small clock changes and increases in core count. You can now get a E5-2699v4 with 22 cores. In a dual socket system that's 44 cores to work with. If the programs you want to run scale well with thread count then that could be a great processor for you. However, if your parallel scaling is not near linear then it may not be the best value. We have a dynamic chart of performance based on Amdahl's Law that may help you decide which processor is best for your uses.
