They are identical. They "system wide" PARI is /usr/local/bin/gp, which is just the SAGE PARI. Benchmarking is tricky. It's probably best to set it up as some sort of game or something, in order to get the best results. -- william --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-devel@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://sage.scipy.org/sage/ and http://modular.math.washington.edu/sage/ -~----------~----~----~----~------~----~------~--~---
