I tested 510.xx, so apparently that isn't the issue. The GLX back end
is the default, but the EGL back end can be selected with 'vglrun -d
egl' or 'vglrun -d {DRI-device}' (where {DRI-device} is a device under
/dev/dri, such as /dev/dri/card0. I should be able to diagnose the
issue using a regular (non-administrative) account, as long as I have
SSH access. I will e-mail you an SSH public key.

How would I select one or the other back end?
And yes, giving you access to the workstation should be fine.
Let me run some more tests myself, but the workstation is on
production, so I have limited timeframes to test.

I assume that you are using the GLX back end when the error
occurs, but I couldn't make the error occur with the EGL back end
either. Which nVidia driver version are you using? I can try to
match your driver version as closely as possible in case that has
something to do with the failure.
Otherwise, I think the only way forward is to get temporary access
to a machine on which the failure can be reproduced.

Hi DRC,
Just tested and it does not fail just using the local X

Do you mean on a local attached display? That won't be
easy, since this graphics workstation is part of a
cluster located far away from me or the user getting
this bug.
I have just contacted Tecplot Support and I'm waiting
for their response and a trial license to test myself
using my own environment.
The 3D X server is on the VirtualGL server, which should
be the same machine on which Tecplot 360 is installed.
Unless the machine has been configured otherwise, the 3D
X server should be listening on Display :0.0, so try:
xauth merge /etc/opt/VirtualGL/vgl_xauth_key
LD_PRELOAD= DISPLAY=:0.0 ./Tec360_FlowViz_batch.sh
I remember to have to preload libvglfaker.so for
starccm+ to work properly. Anything similar perhaps
needed here for tec360? Just some more guessing. Worth
a try?
Preloading libvglfaker.so is literally what vglrun
does. I am not trying to make Tecplot 360 work
properly. I am trying to make it fail.
Thanks,
Richard

I tried it with '$useVGL = 1' as well and was still
unable to reproduce the issue. (Note that, from
the point of view of the application, setting
'$useVGL = 1' in turbovncserver.conf or starting
the TurboVNC session with '-vgl' is the same as
launching the application with 'vglrun +wm'.)
I also tried with both CentOS 7.9 and CentOS Stream
8. My CentOS 7.9 machine has a Quadro K5000 with
driver v470.xx. My CentOS 8 machine has a Quadro
P620 with driver v510.xx.
Is there any way that you could try running the
Tecplot batch job on the 3D X server without
VirtualGL? If it fails in the same way, then it
isn't our bug.

Hi DRC,
sorry, I forgot to comment out that module
command, that would only add the Tecplot
installation PATH to the bash PATH variable,
But as I see from your output the tec360 command
in Tec360_FlowViz_batch.sh started fine, so it is
already in your PATH, so all good.
Did that tec360 run end without errors?
Is your setup also using $useVGL = 1; in
/etc/turbovncserver.conf ?
Just guessing possible differences.
Thanks for testing,
Richard

Please clarify how this is supposed to work.
'module load' is not a valid Bash command.

Hi DRC, hi all,
First, thanks DRC for this great software!
We are having some issue with Tecplot /
tec360 and VirtualGL:
Some system specs:
Rocky Linux 8.5
VirtualGL-3.0-20211119.x86_64
turbovnc-2.2.90-20211222.x86_64
NVIDIA Corporation GM204GL [Tesla M60]
Tecplot 360 EX 2021 R2, Version
2021.2.1.9698 (Feb 3 2022)
VirtualGL is configured with both GLX +
EGL back ends.
$useVGL = 1; in /etc/turbovncserver.conf
While trying to run tec360 on batch mode
we get the attached error output.
Here the last 10 lines:

Any ideas what is going wrong?
When running with tec360 option
"--osmesa" all runs fine, but it takes
17 min to run.
--osmesa
Bypass the OpenGL library and use
the LLVM OSMesa library for off-screen
image rendering. This option does
not require an X server connection.

Richard
