[sage-combinat-devel] new computer on the sage cluster

2012-08-26 Thread William Stein
Hi Sagemath-Users,

The sage-combinat group and I obtained some support from the NSF, and
used it to buy this new powerful computer, which is now on the
sage.math.washington.edu cluster:

 combinat -- mainly for combinatorics research (192GB RAM, 64
cores, Opteron)

[sage-combinat-devel] implementation of cluster algebras

2012-08-26 Thread Hugh Thomas

Hi!

Christian Stump and Gregg Musiker have written code implementing many 
methods related to cluster algebras.  This spans several tickets.  The 
first substantial one is #10527.  

I have reviewed it and am willing to give it a positive review for 
correctness.  I have not done a lot of Sage development, so I would be 
happy if someone else were to take a look at the design aspects, but if no 
one leaps in (or expresses an intention to do so), I will set a positive 
review myself.  

The version in the combinat queue is not quite up-to-date, so if you want 
to take a close look, please look at the version on the trac server.

cheers,

Hugh
