Hi!
When David Joyner tried to install my group cohomology spkg in
sage-4.3.alpha0, the package was not downloaded. He reported:

For a good part, that was just an instance of a general issue with

Hello everybody !!!
Reviewing patch #7533, Rob Beezer noticed that the Graph function to
compute the distances between all the pairs of vertices in a Graph (
shortest_path_all_pairs(), written in Python ) is much slower than
computing independently the distances between all the pairs of
vertices i
No answer to the main question, but just completing the timings:
sage: G=graphs.RandomGNP(300,.1)

CPU times: user 3.67 s, sys: 0.00 s, total: 3.67 s
Wall time: 3.72 s
sage: time d=networkx.all_pairs_shortest_path(G)

You can obtain "some" c_grah in Sage with
cG = G.copy(implementation="c_graph")
I don't know how far the development is though.

Well, it still might be interesting to check what sage does in
the .sage dir. Does it read all files

We have never had success in contacting Komei Fukuda, who should be
the official contact for cddlib. I don't understand why he has never
responded. He did just update his ETH webpage, so perhaps its worth
trying again (I think he may have had a visiting position somewhere

My colleague discovered that the plain hard disk read speed was very low
due to a configuration problem. This has sped up the transmission a lot!
We'll test the system the next day a lot of students log in at once and
report back.
So you were right, Jan, the server was the place to look. You've cl

Of course, any modern Sun is 64-bit.

I need help integrating a Python/Cython program (calculation/

animating graphics). If anyone has experience integrating different
languages with Sage and the notebook, experience combining Python (and
