Hello,
at first: thanks again for the help. You guys are awesome  

 .
So. Here is my little problem.
I have access to a lot of very different computers (at home, private servers, business servers, university servers, cloud stuff like amazon ec2 and so on...). 95% are linux based. 
The servers with free resources that are online anyway are already mining on ypool. 
But what about all the other resources i could use? I have some values like collisions/min of the miners, Share value/h on ypool and $/h i have to pay for cloud resources or electricity costs but i do not know how to "connect" these values.
Can somebody help me to find out what miners are profitable and what is just a waste of time/money? 
Thanks.
