In this third post on Docker and Nvidia-Docker we will configure “kernel user namespaces” for use with Docker. This will increase the security and usability of Docker on your desktop. This is a relatively new feature in Docker and is a key component for the viability of “Docker on your workstation”.
The short answer to that question is, yes. If you want to know why you would want to do that then read on.
In this second post on Docker and Nvidia-Docker we will do an install and setup on an Ubuntu 16.04 workstation.
Docker containers together with the NVIDIA-docker can provide relief from dependency and configuration difficulties when setting up GPU accelerated machine learning environments on a workstation. In this post I will discuss motivation for considering this.
NVIDIA’s Pascal GPU’s have twice the computational performance of the last generation. A great use for this compute capability is for training deep neural networks. We have tested NVIDIA DIGITS 4 with Caffe on 1 to 4 Titan X and GTX 1070 cards. Training was for classification of a million image data set from ImageNet. Read on to see how it went.
You got your new wonderful NVIDIA Pascal GPU … maybe a GTX 1080, 1070, or Titan X(P) … And, you want to setup a CUDA environment for some dev work or maybe try some “machine learning” code with your new card. What are you going to do? At the time of this writing CUDA 8 is still in RC and the deb and rpm packages have drivers that don’t work with Pascal. I’ll walk through the tricks you need to do a manual setup of CUDA 7.5 and 8.0 on top of Ubuntu 16.04 or 14.04 that will work with the new Pascal based GPU’s
I have a Titan Black, Titan X (Maxwell) and a new Titan X (Pascal) in a system for a quick CUDA performance test. Install is on Ubuntu 16.04 with CUDA 8.0rc. We’ll look at nbody from the CUDA samples code and NAMD Molecular Dynamics. It is stunning to see how much the CUDA performance has increased on these wonderful GPU’s in just 3 years.
Intel’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.
The new NVIDIA GeForce GTX 1080 and GTX 1070 GPU’s are out and I’ve received a lot of questions about NAMD performance. The short answer is — performance is great! I’ve got some numbers to back that up below. We’ve got new Broadwell Xeon and Core-i7 CPU’s thrown into the mix too. The new hardware refresh gives a nice step up in performance.
Just got a NVIDIA GTX 1080 for testing. I hacked up an install with Ubuntu 16.04 and CUDA 7.5 along with a beta display driver that works! First run after compiling the cuda samples nbody gave 5816 GFLOP/s! A GTX 980 on the same system does 2572 GFLOP/s. However, it’s not all good news …
