Have you checked if your processors are actually running at the full
2.00 GHz? Most linux distributions throttle the CPU to conserve power
nowadays, using an "on demand" policy. I have seen less than perfect
adjusting of the CPU speed under low load. Try fixing your CPU speed
to maximum and see if
Hi,
Memory leaks are annoying. For instance #9298. Could somebody have a
look at it?
Thanks in advance!

Indeed, but I often use the trick sum( some_list_of_booleans ) to

I've fixed that page so it should work
Sage 4.3 exhibits the same slowness issue in Ubuntu.

Hello Everybody !!
I just had to write a doctest saying "If this bipartite graph is not a
forest, then is has an even cycle"
This can of course be written "(not g.is_forest() and g.has_even_cycle())"
I would have like to have some "implication operator", to be able to write :

there is an interesting proof out there that is being taken at least a

I will try downloading Sage 4.3, and see if that fixes the problem.

Thanks for the answer, I downloaded the new version on the website
(version 4.5)
and I followed this tutorial :
https://help.ubuntu.com/community/SAGE
unfortunately I have still problems :

to do that ?)

That's weired. Which version of Sage are you running? (in virtualbox
and in ubuntu)
Also, the obvious thing, systems get slow if other processes run. What

Hi all,
at this stage I would also like to advertise trac 9650, which if it
passes review would add support to Sage for differential form
calculations. It's only a "small" step to algebraic topology from
there.
