Re: [X2Go-User] Suspending sessions causes performance slowing down
I can answer about the GUI toolkit. I was debugging MATLAB performance issues
last week so I looked into this.
Matlab uses the jobamp/jogl framework. https://jogamp.org/jogl/www/
In my Ubuntu/x2go/MATE setup, it falls back on a "software OpenGL" mode, which
actually looks like MESA/Gallium software rendering:
In Matlab:
>> opengl info
Version: '2.1 Mesa 17.1.3'
Vendor: 'Brian Paul'
Renderer: 'Mesa X11'
MaxTextureSize: 16384
Visual: 'Visual 0x61, (RGBA 32 bits (8 8 8 8), Z
depth 16 bits, Hardware acceleration, Double buffer, Antialias 0 samples)'
Software: 'true'
HardwareSupportLevel: 'none (known graphics driver issues)'
SupportsGraphicsSmoothing: 0
SupportsDepthPeelTransparency: 1
SupportsAlignVertexCenters: 0
Extensions: {152×1 cell}
MaxFrameBufferSize: 16384

This defines how long nxagent should sleep. The unit should be microseconds but
there's a ticket for doublechecking that because it looks like a mixup happened
during implementation (https://github.com/ArcticaProject/nx-libs/issues/928).

Re: [X2Go-User] Suspending sessions causes performance slowing down
Usually you can instruct java to use xrender by calling java with
"-Dsun.java2d.xrender=true" or run "export
_JAVA_OPTIONS=-Dsun.java2d.xrender=true" prior to starting the java
application. You can also configure that globally:
https://serverfault.com/questions/270924/setting-java-runtime-setting-for-all-users-on-a-client-pc
This generally should reduce the number of pixmap related calls. But I
don't know if it will have any effect on jogl.

Re: [X2Go-User] Suspending sessions causes performance slowing down
I did some quick benchmarks by rotating a simple 3D model with and without
benchmarks, see script at the end. Transparency is turned off by setting alpha
= 1.
Baseline:
Without transparency: 71±11 ms per frame
With transparency: 781±112 ms per frame
Using export _JAVA_OPTIONS=-Dsun.java2d.xrender=true:
Without transparency: 69±12 ms per frame
With transparency: 771±110 ms per frame
So within the measurement variance.
function matlab_graphics_perf_test
Nang = 50;
azvec = linspace(-180, 180, Nang) + 45;
el = 27;
figure(9)
[x,y,z] = peaks;
alpha = 0.5;
surf(x,y,z, 'FaceAlpha', alpha)
axis vis3d
Tvec = zeros(size(azvec));
for azloop = 1:length(azvec)
tic
view([azvec(azloop) el])
drawnow
Tvec(azloop) = toc;
end
fprintf('Average frame time: %g ± %g s\n', mean(Tvec), std(Tvec));

Re: [X2Go-User] Matlab graphics performance when running in x2go
I finally figured it out! Now I can run Matlab R2019b on Ubuntu 18.04 LTS with decent graphics performance over x2go, even with transparency using the Mesa llvmpipe software OpenGL driver. Benchmark for a simple scene: No transparency: ~40 ms per frame With transparency: ~58 ms per frmae So still some performance penalty for transparency, but much better. HOWTO: First install LLVM: sudo apt install llvm-dev I downloaded mesa-20.1.0 (latest version right now) and configured it like this (in the unzipped source directory): mkdir build cd build meson -D glx=gallium-xlib -D gallium-drivers=swrast -D platforms=x11 -D dri3=false -D dri-drivers="" -D vulkan-drivers="" -D buildtype=release -D optimization=3 -Dprefix=/usr/local/mesa-20.1.0/ Then I built and installed it as follows: ninja sudo ninja install Then to make Matlab load the new driver, I needed to modify Matlab's lib search path: cp $MATLAB_DIRECTORY/bin/.matlab7rc.sh ~ Edit the file ~/.matlab7rc.sh, find the glnxa* section and add /usr/local/mesa-20.1.0/lib/x86_64-linux-gnu to LDPATH_PREFIX Add to your .profile: export MESA_GL_VERSION_OVERRIDE=3.0 Seems like anything will work for the version override except for 3.1, but I didn't debug this further. — Johannes Töger Associate Senior Lecturer Cardiac MR Group Department of Clinical Sciences Lund, Clinical Physiology Lund University, Sweden -Original Message- From: Ulrich Sibiller Sent: Wednesday, May 27, 2020 14:29 To: Johannes Töger Subject: Re: [X2Go-User] Matlab graphics performance when running in x2go Thanks!

Re: [X2Go-User] Matlab graphics performance when running in x2go
I just did some more testing, and found some rare crashes. Using MESA_GL_VERSION_OVERRIDE=3.1COMPAT seems more stable. — Johannes Töger Associate Senior Lecturer Cardiac MR Group Department of Clinical Sciences Lund, Clinical Physiology Lund University, Sweden -Original Message- From: Ulrich Sibiller Sent: Tuesday, June 2, 2020 21:10 To: Johannes Töger Cc: x2go-user@lists.x2go.org Subject: Re: [X2Go-User] Matlab graphics performance when running in x2go Thanks, I have included that in the wiki: https://wiki.x2go.org/doku.php/wiki:development:glx-xlib-workaround#matlab_2019b Uli On Tue, Jun 2, 2020 at 8:56 PM Johannes Töger wrote: > > I finally figured it out!
