what happens when save and quit a worksheet in sagenb?
I created a worksheet in www.sagenb.org. One cell takes much computing(ploting) and it stuck there. I saved and quit the worksheet. After coming back, the worksheet cannot compute 1+2=? in another cell. Is it because the original computing keeps working even when I quit?
Possibly. Can you go back to your main page and see if it says "running"? If not, it should have quit.
Hi, I tried it and am sure it is not running. I later figured it out it's possibly that it is because sagenb.org becomes slow.
Yes, that is possible. sagenb.org isn't necessarily meant to be a production server, although often it is very, very good. If you are doing some hardcore computing, you might as well put Sage on a machine you can ensure is always available just for yourself!
