X2Go being used to access High-Performance-Computing cluster at University of Pennsylvania

I manage the HPC cluster for a number of medical imaging research labs at Univ. of Penn, at the School of Medicine and other groups. So a small slice of the big pie, with currently about a half dozen regular X2Go users who (very succesfully!) use it to remotely access our compute cluster and ancillary servers. It really works very well, hats off to you and your team. Without X2Go, the performance of X11 apps is barely usable over remote VPN connection. Sometimes we also use it within the local university network to get better graphics performance. One user uses it via cellular from his laptop on the train during his commute, going through VPN, and gets good response for a 2D image analysis tool we use.

Editor's Note: X2Go does have options for image compression, like using JPG and/or PNG. Not all image compression algorithms are lossless, and thus there may be artifacts in the images (i.e. the image displayed through X2Go may look slightly different than what it would look like on a regular X-Server screen), depending on which algorithm and which compression level you choose.

If you're using fMRI/X-Ray/Mammography/… images or similar medical imaging displayed through X2Go for clinical purposes (deciding whether a certain patient requires a surgery etc.), you should absolutely make sure that you're using a lossless compression or no compression at all, or else you might be seeing things that aren't actually there, or missing things that are there.
