Thank you very much for your message. I used simon_two_descent(), for [0,0,0,- 9588522241, 399039337488961], but Sage says " name 'ans' is not defined". I do not know what 'ans' is. Best, Raman On 2/6/14, William Stein wrote: > On Wed, Feb 5, 2014 at 1:06 PM, raman kurdi > wrote: >> Hi Sage, >>

I've used rocks before, it just sets up a shared NFS for the nodes afair. Install once and run it on any node you want. There is nothing in Sage that is particularly specific to clusters. Split up embarrassingly parallel tasks any way you want. If your problem is tightly coupled you need to use

Version 5.0 is very old, try installing 6.1.1. Note that 6.1 was very recently released but had a similar issue with latex in the notebook, for which 6.1.1 was a bugfix release out today. John Cremona On 5 February 2014 19:39, Andy Miller wrote: > Greetings -- > > I think we're having an issue

Greetings -- I think we're having an issue with Typeset on our local Sage server, but I'm not quite sure how to fix it. As you see in the attached screenshot, for some expressions, typeset just outputs the LaTeX code instead of processing it; I've tested the same command on my computer and with

You need post working code that demonstrates your problem and the error message if you want to get help. There is no built-in limitation on list length, but you might exceed your computer's RAM. Check "ulimit -a". On Tuesday, February 4, 2014 5:07:58 PM UTC, Jeroen wrote: > > Hi, > > I'm using

Hi, I'm using Sage scripts to run tasks in batch. They look like: def dostuff(X): result = [X] #plus irrelevant calculations return result print dostuff([1,2,3,4,n]) This worked fine for all recent data sets with an input array size of 1.0 - 2.4M records. However Sage crashes if
