-It is possible to run a VisIt client on your local workstation,​ with the data and render processing happening on a cluster node.  However, is is easier to use one of the visualization nodes (chpclic1 or chpcviz1) to run the interface. ​ In order to do this, load the module ''​chpc/​compmmech/​VisIt/​2.12.3-VNC'',​ and start VisIt with the command ''​vglrun visit''​. ​ This will get you a serial version of VisIt, which is adequate for processing smaller data sets. +It is possible to run a VisIt client on your local workstation,​ with the data and render processing happening on a cluster node.  However, is is easier to use one of the visualization nodes (chpclic1 or chpcviz1) to run the interface. ​ In order to do this, load the module ''​chpc/​compmech/​VisIt/​2.12.3-VNC'',​ and start VisIt with the command ''​vglrun visit''​. ​ This will get you a serial version of VisIt, which is adequate for processing smaller data sets.

 However, the mesa module will clash with the VNC implementation of VisIt, therefore you will need to unload it in your VNC session before starting VisIt. However, the mesa module will clash with the VNC implementation of VisIt, therefore you will need to unload it in your VNC session before starting VisIt.
