Thank you for this. I was considering EC2 mining and you just saved me a lot of legwork.
No problem! Hope I saved you some money too!
But I've seen 3 different people mention they are working on new cuda code that is 2x-3x faster than current cgminer on nVidia GPUs. Still won't make the Tesla EC2 worth while, but it's closer.
Care to link to a post? The next generation of Tesla still greatly underperform AMD cards for mining. With this setup the profit/loss is less than .25. However, I'm curious about improvements in nvidia kernels.
