Introducing Preemptible GPUs
A month ago I ran benchmarks on CPUs vs. GPUs on Google Compute Engine, and found that GPUs were now about as cost-effective as using preemptible instances with a lot of CPUs: <a href="http://minimaxir.com/2017/11/benchmark-gpus/" rel="nofollow">http://minimaxir.com/2017/11/benchmark-gpus/</a><p>That was <i>before</i> preemptible GPUs: with the halved-cost, the cost-effectiveness of GPU instances now doubles, so they're a very good option for hobbyist deep learning. (I did test the preemptible-GPU instances recently; they work as you expect)
