I went the other way, from computations on the server to computations on the client. Here's why: if you have a large number of players, your server costs will become a real problem. But the number of clients available to do calculations expands with the number of players, and client CPU time costs you nothing.
What you need to do is break the task down into maybe 100 iterations and call it 100 times, something like the code here, which shows a prime number routine coded conventionally and then coded in setTimeout() pieces. http://dreaminginjavascript.wordpress.com/2008/08/02/functions_are_weird/ Add a progress bar and you're good.
