I have thought about the same thing when playing with deep learning at home, until I put electricity bills into the equation. A beast like what the author has built, with full power, will cost $0.1/hour in electricity bill alone at where I live ... which almost equal to the cost of a p2.xlarge spot instance on Amazon.
So if someone else is paying for the electricity, build your own gig, otherwise, Amazon is pretty hard to beat.
- nathancahill 9y agoSame goes for Bitcoin mining.
- hueving 9y agoThe spot pricing is pretty crappy to compare to since you only get to use spare capacity. If you have any project where availability matters then you should compare to the on demand price of $0.9/hour. If availability doesn't matter, it means you wouldn't run the box full time anyway, in which case your power calculation is too high.
- marcosdumay 9y agoIt's a processing task. You run it for a fixed CPU time. Wall time may or may not matter depending on the application. You almost never take availability into account, but taking spot prices will increase wall time.
