Do you see something different in EC2 Console? https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-resource-limits.html https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-reso... Anyway, the solution to the problem is request a Limit Increase using the relevant form: https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-resource-limits.html#request-increase https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-reso...

g2 are the EC2 instances designed for graphics usage; they're typically aimed at GPU encoding rather than machine learning, like what the blog poster is aiming for. Not to say they couldn't cover either, but the GPU classes used between the two instance types are very different; g2 is GRID based, p2 is using Tesla. I don't think that the GRID GPUs have RDMA, although not being into machine learning I don't know how important that would be. The real problem is that the documentation you've linked to (The EC2 FAQ) actually shows that the p2 instances should have a spot limit of 1, but when I check my account, it's actually 0 for all sizes of p2 instances. It doesn't seem to matter what region I choose, it just doesn't match the FAQ; p2 is on request only.

Exactly. The lack of (and indeed, plain wrong) communication to customers and support staff is the biggest problem here.
