X11 Forwarding failed [qsub: DISPLAY not set]

I am trying to debug a oneDNN application with the Intel Inspector GUI (inspxe-gui), however, I have not been able to successfully set up X11 Forwarding in DevCloud. Whenever I try to connect from my Ubuntu 20.04 computer to devcloud with `$ ssh -X devcloud`, a message is displayed on top: "X11 forwarding request failed on channel 0"

When trying to access a compute node from the login node with `$ qsub -X -I`, a message is displayed and the command is canceled: "[qsub: DISPLAY not set]"

Do you know how I can address this issue? Thanks!

Hi,


You can run the analysis using command line interface in your linux machine. Please refer the below document for more details regarding command line interface : 

https://software.intel.com/content/www/us/en/develop/documentation/inspector-user-guide-linux/top/co...


After the collection of analysis result , copy the result folder to your windows machine using the scp command from devcloud. 


scp devcloud:~/file . 


Documentation link : https://devcloud.intel.com/oneapi/documentation/job-submission/#transferring-files.


You can open the result in the inspector of same version where you ran the analysis in linux.


Thanks,

Jaideep

Hi Jaideep, thanks for your response! Is there another way to run graphical applications (like inspxe-gui) on DevCloud that is supported?
