10/1 1pm Update: We continue to troubleshoot the problems with the visualization nodes and apologize for the inconvenience.
We have set the UB-HPC and RPCI visualization nodes offline while we track down what is causing issues to launch GUIs. Updates were done Tuesday to Cuda but we've been unable to determine what is exactly causing these problems. Thanks for your patience!
