What you think about deadline for v2.11 by the end of April? 2 months should be enough to make issue list much shorter
Sebastian Jennen
@zebastian
sure, maybe even shorter than two months, we could start making improvements and see in a week how we estimate the work and set a final limit.
Martin
@acidhunter
i got a improvement for netrender, maybe

Before I will be able to start with OpenCL I need to buy new GFX card. I have just found that my AMD Radeon HD 7800 is no longer supported by propertiary drivers. It menas that it cannot work properly with OpenCL. I'm going to buy nVidia GTX 1050 which should work well with linux nvidia-driver. Then I will be able to work with OpenCL and Cuda

i ran sonarqube on the project. something like coverity but way more detailed / pedantic.
here is the webreport: https://sonarqube.com/dashboard?id=mandelbulber2 in the future this may be helpful to refactor the code and reduce the complexity of functions and classes (except for fractal_formulas.cpp :) ) here is the complexity report: https://sonarqube.com/component_measures/metric/file_complexity/list?id=mandelbulber2

It's interesting tool. But it probably need some configuration. 600 of "critical bugs" are located on moc* files which we cannot edit (Replace "reinterpret_cast" with safer cast)

right now i am installing a new Radeon RX 480. Lets see how this performs with opencl :D
Krzysztof Marczak
@buddhi1980
Let me know how it works. Which driver will you use? amdgpu-pro or opensource amdgpu driver?
Sebastian Jennen
@zebastian
Sadly Amdgpu- pro, since its performance is Vetter.

amd card up and running, mandelbulber opencl with default mandelbulb and ssao and all shaders on renders in 35,25 seconds

... in 10000x10000 resolution :D

I have just installed nVidia GTX 1050. Woks perfect with OpenCl, so I will be able to continue OpenCl development

@mclarekin
cool!!

@buddhi1980
I would like to do benchmark of our systems to compare nVidia and AMD performance with OpenCl
I have used Mandelbulber 1.12 and rendered settings pasted below in time 156s (OpenCl enabled, "Full: all shaders" mode)
The same on CPU is rendered in 1h 30m.
@zebastian , can you do the same test on your new GPU?

That is so fast! I will try it

@mclarekin
758 seconds (I want a new GPU), and I think it would have taken about 4 -5 hours on CPU
Krzysztof Marczak
@buddhi1980
@mclarekin what gfx card do you have?
mclarekin
@mclarekin
AMD Radeon R9 M265X openGL 4.5 openCL 1.2

Wednesday im back, then i will do the Showdown benchmark :)

111,95sec on Radeon RX 480 :D
Krzysztof Marczak
@buddhi1980
Thanks. It looks like AMD and NVidia have similar performance with OpenCl
Krzysztof Marczak
@buddhi1980
This test was needed for me to do decission about usage of CUDA. But now I see that it doesn't make sense. OpenCL on nVidia cards works also very well.
Sebastian Jennen
@zebastian
you are welcome. :)
the opencl version seems to be properly implemented by nvidia, though a little late. I think opencl should be close to hardware optimum on both platforms, as long as we use standard features of opencl and do not depend on specialties, which are only present in CUDA. But since we are "only" using the GPU as an offloader for the heavy rendering shaders, we should be fine with this.

hello there,
latest git master on archlinux shows some font scaling errors

other qt apps works well

setting size of fonts does not change anything
blob
Krzysztof Marczak
@buddhi1980
Which font settings have no influence? When you change in system settings in Mandelbulber preferences dialog?
Martin
@acidhunter
blob
ui style will be applied
but not the font setting
i tried other qt apps on my workstation
font settings are working there
Krzysztof Marczak
@buddhi1980
So if you change UI font size in Mandelbulber, font size is changing
But if you change it in the system no change is visible
Am I correct?
Martin
@acidhunter
yes
no sry^^
i try to explain
UI font size in Mandelbulber is NOT changing
Krzysztof Marczak
@buddhi1980
I need to install archlinux to investigate it. Under Debian, Ubuntu and Windows it works properly
Martin
@acidhunter
okay
i could do this for you and give you a remote
Krzysztof Marczak
@buddhi1980
do you use TeamViewer?
Martin
@acidhunter
i can install it
Krzysztof Marczak
@buddhi1980
this would help
Martin
@acidhunter
i think i found something, seem to be arch related
Krzysztof Marczak
@buddhi1980
is this something which I should know?
Martin
@acidhunter
i got this errors in all qt apps
Failed to compute left/right minimum bearings for "mtx"
