is there anyway to share my CPU over a LAN ?

so i can like let 1 computer use another computers CPU over a LAN

You could use Remote Desktop Connection to remotely connect to the other computer...essentially offloading the workload to that machine. But I don't believe you can pump actual CPU cycles over the lan the way you're describing it.

You can't share over the LAN. In any case, the LAN bandwidth is so small compared to what is required for meaningful processor teaming that it would be useless anyway.

Not over the LAN.

I think it really depends upon what you are trying to do.
If you are trying to use clock cycles directly well it is not possible but if you plan to share some load that does not have Real Time priority it can be done.
load can be shared by having a multi-threaded program that you can assign to use different CPUs in a non time critical manner.
a prime example of this is SETI@Home project where any one can connect to the network and the local CPU cycles are used to help interpret radio telescope data.

That sure doesn't sound like what he's trying to do.
