One option would be to use the web2py scheduler to run the calculations as 
a background task. As results are generated, they could temporarily be 
stored in a special database table. From the browser, you can then make 
periodic Ajax requests (perhaps every few seconds) to check for new results 
in the special table.

As an alternative to the Ajax polling, you could use server push (e.g., 
Websockets or Server Sent Events) to push results to the browser. If you 
want to take that approach, consider external pubsub servers such as Nchan 
<https://github.com/slact/nchan> or Centrifugo 
<https://github.com/centrifugal/centrifugo>, or realtime services such as 
Realtime.co, Ably, Pusher, Pubnub, or Firebase.
