Magma is a computational algebra system maintanied by the Computational Algebra Group, School of Mathematics and Statistics, University of Sydney.  The Courant Institute has an agreement with the Simons Foundation covering US Educational and Scientific Research Institutions.  This license allows us to install and provide Magma for the Courant community.  Based on this agreement, we currently have Magma installed for use on TWO hosts, both running CentOS 7:

snappy1.cims.nyu.edu
snappy2.cims.nyu.edu 

Attempts to run magma on any other CIMS host will result in a licensing error.

These instructions should get any Courant member with a CIMS account up and running with Magma:

user@pubbox52[~]$ ssh snappy1
user@snappy1[~]$ which magma
/opt/bin/magma
user@snappy1[~]$ magma
