Why do you need to interrupt it?

There's Abort[] for a hard abort

There's Interrupt[] which will interrupt and ask what you want to do

There's Dialog[] that'll give you an interactive subsession at that 
point so you can inspect the kernel state

There's Throw[] for returning (a value) from arbitrarily deep in an 
expression

There's Return[], as well as the undocumented two argument form 
Return[val, fun] which returns from function fun

There's Break[], Continue[], Goto[] ...

As well as others.  Can you explain why and how do you need to interrupt 
the calculation so we can give a more specific answer?
