Ok i have this code running on ubuntu ami from amazon. using c1.extralarge.. or what ever its called..
https://github.com/Chemisist/primecoinIm getting about 1600pps out of this box.. and it costs are about .50 an hour.. just a fyi to all..
This is a pretty bad result for $0.5/hour.
You should look for other providers.
Are you guys still getting blocks? 8K pps here, no blocks for 10hours!! (I found blocks before that every hour or so)
