Hi, We are looking for some guidance in installing an upgraded Python on our cluster. Our cluster was installed with Rocks 6.0, is running CentOs 6.2, and has python-2.6.6, gcc-4.4.6. We would like to install an upgraded version of Python along with the following modules NumPy Scipy (which will require a compatible version of the Atlas libraries) Mayavi (which will require a compatible version of vtk) We were wondering if anyone has experience in installing these packages, what are the best combinations of compatible versions, what other upgrades will be needed (e.g. will we need to upgrade the gnu compilers to install the latest versions) and where these should be installed (local disks, /share/apps, other?). A little more background, our students are currently working with a local installation using Python-2.7.1 numpy-1.5.1 scipy-0.9.0b1 Mayavi-3.4.0 ATLAS-3.8.3 vtk-5.4 We would like to install these packages in a more appropriate, cluster-wide area and upgrade these packages as appropriate. We are also aware of a Rocks python roll which contains python-2.7.2 and an upspecified version of NumPy (is it possible to find out which version, before installing the roll?).
