I am upgrading from RHEL 7 to RHEL 8 and my jobs that ran fine on Redhat 7.9 but fail on Redhat 8.10
on 7.9 I just had to have
export DISPLAY=:0
and the jobs would run fine, but on RHEL 8 the engineering apps like abaqus/ansys/etc fail because they can’t find a ??virtual monitor?? to run on?
I assume it has to be an OS issue, but it is odd and I don’t understand why it is failing
any ideas?
Hi, First thing, change the subject of this post. It should have DISPLAY=:0, not DESKTOP.
DISPLAY is a environment variable related an X server to display GUI. Read this…
xorg - What is the $DISPLAY environment variable? - Ask Ubuntu
So I’m not sure how it is related to running your jobs, as I don’t think a job should be tied to DISPLAY variable.
yes, you are correct, sorry for my mistake.
I am noticing that when typing
ps -ef | grep Xorg
that it shows /usr/libexec/Xorg vt2 instead of /usr/libexec/Xorg :0 vt2 like it does on RHEL 7.x
the applications ran through PBS need to interact with the GPU
right now it just says ‘Desktop :0 not available’ in the logs.
I didn’t have this issue on RH 7
