There are many servers in this world that contain multiple cpu's which are idle most of the time. Even if the db is working at optimal performance.
I think that's a waste of money.
On my laptop and desktop at home, I run Grid Computing software. These tools gather data from a server, compute difficult formula's and return the result to that original server. These projects are supported by millions of people all over the world. They are here to help to find a cure for diseases like cancer and aids. Even a special project to fight Anthrax was supported when Saddam was threatening the world with chemical warfare...
The important fact is that these tools only use cpu-time thats not being used at the moment. They don't burden the other applications running. If Oracle uses all cpu's to the fullest, these tools stop until there's cpu-time left by the system.
Does anybody use these clients on a Oracle server? Do you think it's wise to do so? I can understand that there's a certain risk, but watching multiple cpu's asleep while they could do some good is a pitty.
