Sage

Sage is a free open-source mathematics software system licensed under the GPL.

Seit dem 14.12.2012 steht "Sage" auch im Pool unter Ubuntu 12.04 zur Verfügung. Damit steht jedem einzelnen Nutzer eine eigene Quadcore CPU und 4GiB Ram zur Verfügung :-)

Jeder User kann einfach einen lokalen Server starten:

~$ sage
