I noticed there is no bug in sage 7.4 (sagenb.org). Pynac was updated to 0.2.2 (sage-4.7.1.alpha1) and then to 0.2.3 (sage-4.7.1.alpha4) according to sage 7.4.1 changelog. Where do I fill the bug? I've already filled a bug at the "Sage Notebook Bugreport", is it enough? Is it mandatory to ask for

No. Also note that sagenb.org is on a single computer shared among tens of thousands of users, so if you want to do something computationally expensive you're better of installing Sage on your own hardware. On Tue, Oct 11, 2011 at 8:38 AM, juaninf wrote: > Exist sagenb.org with openmpi module? >
