Building a Data Science Workstation (2017)

Update, 3/14/2018: While I’ve still maintained the same basic workstation, I have done some upgrades. Before GPU prices skyrocketed, I added a 1080ti to workstation along with the 1060. However, this required an upgrade of my case to fit both. I ended up getting a Corsair 760T, which is an enormous increase in space over the Corsair mid-tower I had before.

Since I was already in the case, I also added a AIO water-cooler to my CPU, a Corsair H115i Pro. While this wasn’t strictly necessary (I wasn’t having overheating issues with a single GPU and overclocked CPU), with two GPUs I figured that it was a good precaution. The water-cooler is also much quieter than my original air-cooled heatsink, which is nice.

So now I have a huge amount of open space, which is great for airflow, a dual-GPU rig and depending on how you calculate things, I’m at around $3000 for a workstation that should serve me well into the next several years (hopefully more!)

For all the downsides of social media these days, the people I’ve met and the inside jokes bring me immense joy. From just this one tweet, several people messaged me aghast at 1) the idea of multi-gigabyte XML and that 2) I apparently have a computer for just this purpose!

Recently, I did build a workstation as a test bed for learning more about data science, specifically in the areas of Docker and GPU computing. Here’s what I built.

Machine Specs and Assembling from Parts

While there are several specialist workstation companies like Titan Computing that sell configurable workstations, assembling a computer from parts is pretty easy, and more importantly, can be significantly cheaper if you choose ‘consumer-grade’ parts instead of ‘server-grade’. Because I’m not planning on curing cancer or building Skynet with this computer, I opted not to get a dual-chip motherboard and used a single Intel i7 chip rather than going with Xeon workstation class chip(s). I also chose to use standard DDR4 RAM rather than ECC RAM. Here’s the full spec list:

Component Details
CPU Intel Core i7-5820K 3.3GHz 6-Core Processor
CPU Cooler Cooler Master Hyper 212 EVO 82.9 CFM Sleeve Bearing CPU Cooler
Motherboard Asus X99-A II ATX LGA2011-3 Motherboard

Memory Crucial Ballistix Sport LT 32GB (2 x 16GB) DDR4-2400 Memory
Storage Samsung 850 EVO-Series 250GB 2.5” Solid State Drive
Storage Hitachi Deskstar 1TB 3.5” 7200RPM Internal Hard Drive
Video Card EVGA GeForce GTX 1060 6GB 6GB SC GAMING Video Card
Case Corsair SPEC-02 ATX Mid Tower Case
Power Supply Corsair CXM 750W 80+ Bronze Certified Semi-Modular ATX Power Supply
Optical Drive Asus DRW-24B1ST/BLK/B/AS DVD/CD Writer

Total: ~$2000

So for about $2000 and a few hours of time assembling, I have the rough equivalent of an r3.4xlarge instance on AWS ($1.33/hr on-demand at the time of writing). It would take about 1500 hours of usage to breakeven vs. using AWS, but cost isn’t really the point; the convenience of having the computer in my house and not having to do the startup/shutdown/EC2 images/S3/firewall/etc. dance is more than worth it to me so that I can focus on learning instead of operations.

Ubuntu 16.04LTS, CUDA, and Other Installs

While I did use Windows 10 to validate I put together my hardware correctly (and to mess with overlocking settings using the ASUS motherboard tools), I decided to use Ubuntu 16.04LTS as my base operating system. This allows for the most ‘server-like’ operations that I’m used to from a Linux environment. I enabled an internal static IP through my router, and for the most part, I either SSH into the machine from my MacBook Pro or use web UIs such as Jupyter Notebook (and again, remotely from my laptop).

I tried to install the NVIDIA drivers from source for the GTX1060 GPU, but eventually gave up and went the apt package manager route and everything works fine. Though I rarely sit at my desktop, I do have a 4K monitor hooked up to this computer which looks gorgeous with a video card of this caliber, and I have CUDA installed and working as well.

From there, I installed any number of tools from Python, R, Julia, MonetDB, Docker, Neo4j, Postgres, Spark, BlazingDB…any/all of which I hope to write about more in the near future.
