There is no way you can have 200 students all using exactly one sage notebook server on the same port *at the same time* and have it feel snappy still. I've done classes with 30 people at once and that worked OK -- the server I used was sage.math (16 1.8Ghz opterons from 2005). If you ran say 6 different servers, even on the same hardware, at once, that would probably work fairly well. Probably using two of the 8-core 32GB of RAM machines you list below, with say three sage notebook servers on each, would work reasonably well. If you publish the relevant notebooks the students need, and just redirect students from some master login page to one of those six distinct servers, this could work pretty well. > subgroups of students doing the same thing at the same time.

I basically started it as a server from scratch 1 month ago, and over 750 people created accounts on it during the last month. -- William --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
