Can anyone comment on the crazy spot prices for g2.8xl ? they spike really high (they were $26/hr earlier? 10x the on-demand price. I'm guessing someone with enough market share has a job that doesn't want to be interrupted and they bid the spot price up to 10xon-demand, which seems ridiculous since presumably they could arbitrage /w an on-demand, but i guess that once they start the job they don't want to be interrupted? i'm not exactly familiar with the intricacies of the ec2 spot market. ). Also, are they any good for ML? I'm between machines ATM and would like to experiment with some deep CNN for face recognition. At $2.6/hr for on-demand its a bit more than I would like, but if the spot price was less i'd consider it.

Can you checkpoint your work? Most libs I've used support that generally. That way you only lose a bit of time if kicked off, and you don't pay for the hour you get kicked off so it's even cheaper.

I used them for a while for ML, works ok. I also noticed the these spot price spikes with both g2.8xl and g2.2xl. Not really sure why someone (or multiple players, since the prices spike) have set their max bid so high, surely it's worth running an on-demand instance at those prices. Ended up going between two regions to avoid them but it's some hassle, just got a gtx970 in the end.
