Overview

When users are off-site or have slow internet connections, displaying graphics can be cumbersome.  PCDS has explored two solutions for this problem.  The first ("NX technology") gives the user a special remote desktop that is specifically designed to improve the performance of X11 graphics with slow connection speeds.  The second ("Virtual Box") allows the user to directly install the psana analysis environment on their windows/mac machine, so that LCLS data analysis can be done "while on a plane".
