OpenCL / OpenGL and osx crashes - opengl
I've been working on an opencl octree ray caster which is written in openframeworks. It takes point clouds of 5-10m points, builds an octree, passes the octree to the kernel and then runs about 200k raycasts to find point interceptions.
The code is working well enough, with results being rendered through vbo objects. See here and here for a couple of clips (still perfecting the intersection checks).
The problem is, I have been having a whole series of mac black screen moments lately. (I'm on a late 2013 mac pro with a recent el-cap update) I'm pretty sure that the black screens are some form of kernel crash or overload (?). They happen both occasionally when the app is running and also even when OF has been shut down and I've moved on to other work afterwards. Regularly enough to make working a nightmare...
I'm fairly green with opencl and the like but I think that my basic kernel code is sound. I am also including cleanup functions in the c++ on exit. Are there any other simple issues/safeguards that I may be unaware of that I need to be sure to include/I could try in my app?
It may be I need to include more information, happy to update in response to questions.
In hope
S
update:
here's a system report from the latest shut down; happened after a restart after a crash after running the app. I have totally zero clue:

So after much checking, there isn't anything wrong with my opencl code.
The issue appears to be that the GPU has some kind of heat throttling going on; if it hits 55 degrees Celsius it shuts down, boom. Go Apple.
By downloading smcFanControl and gfxCardStatus, turning the fans to full and keeping an eye on the temperature I've got the panics down to a bearable/manageable occurance.
Not great but maybe I need a better laptop.

Android x86 (Android 6.0) is locked at the android animation after booting (VirtualBox)
So, using VirtualBox, I wanted to install Android x86 9.0 on my virtual machine. Following this guide, I've succesfully made it. However, after booting from the GRUB, it stays on the android animation thing. Having a weak ram, I hoped it was because 9.0 needed more power my PC was able to give. So I did it with Android x86 6.0. I made the same installation and all, then when it showed the android animation, I let my PC ran all over the night (during 10 hours so). When I powered on my monitor, it was locked on the same screen. I'm now stuck on this screen, and I don't know what to do to finally start my Android 6.0. I've already made some searches, but all I could find was some answers to display errors, which I have not (I guess). Here is my PC details : *****#******** MMMMMMMMMMMMMMMMMMMMMMMMMmds+.

I found the answer here: https://www.eevblog.com/forum/microcontrollers/openocd-fail-to-open-stm32-nucleo-board/ Evidently OpenOCD cannot connect to USB 3.0 port. I switched to another port and it worked!!! Why no one at OpenOCD instructs that it doesn't work with usb 3.0? I have spent a few days on this problem. I still don't know how to tell which port has 2.0 or 3.0 version looking at the Device Manager.

Device 1 name: Intel(R) Core(TM) i5-4250U CPU # 1.30GHz. Device 2 name: HD Graphics 5000. Has anyone faced this issue before?
It looks like Tessaract enqueues kernels with a work-group size of 16x16, which is a fairly typical tile-size for image processing on GPUs. However, Apple's OpenCL implementation for CPUs has a limitation that work-group sizes can only be one-dimensional (i.e. the second dimension must be 1), and therefore this work-group size will be invalid. The error code you are getting (-54) corresponds to CL_INVALID_WORK_GROUP_SIZE. If you can get Tesseract to run on the GPU instead (HD Graphics 5000), you should be OK.
How to enable OpenGL 3.3 using Mesa 10.1 on Ubuntu
I am trying to get an OpenGL-based rendering engine that relies on OpenGL 3.3 and GLSL 3.3 to run on Ubuntu 13.10 using an AMD Radeon 6950. I want to use the open source drivers (radeon), which rely on Mesa for their OpenGL implementation. Ubuntu 13.10 only provides Mesa 9.2 (implementing OpenGL 3.1) "out of the box". It is however possible to install Mesa 10.1 (implementing OpenGL 3.3) from this PPA as explained in this thread:
StackOverflow: OpenGL & GLSL 3.3 on an HD Graphics 4000 under Ubuntu 12.04
I used the exact same steps as explained there:
1.) Add the PPA Repository
$ sudo add-apt-repository ppa:oibaf/graphics-drivers
2.) Update sources
$ sudo apt-get update
3.) Dist-upgrade (rebuilds many packages)
$ sudo apt-get dist-upgrade
4.) Then I rebooted.
Mesa 10.1 was successfully installed. However, glxinfo, while it now reports that Mesa 10.1 is in use, still reports only OpenGL 3.0 (compat profile) and OpenGL 3.1 (core profile):
$ glxinfo | grep OpenGL
OpenGL vendor string: X.Org
OpenGL renderer string: Gallium 0.4 on AMD CAYMAN
OpenGL core profile version string: 3.1 (Core Profile) Mesa 10.1.0-devel (git-7f57408 saucy-oibaf-ppa+curaga)
OpenGL core profile shading language version string: 1.40
OpenGL core profile context flags: (none)
OpenGL core profile extensions:
OpenGL version string: 3.0 Mesa 10.1.0-devel (git-7f57408 saucy-oibaf-ppa+curaga)
OpenGL shading language version string: 1.30
OpenGL context flags: (none)
OpenGL extensions:
Why is that? How can I enable OpenGL 3.3? As can be seen by comparison in the StackOverflow thread that I mentioned, it is possible to have glxinfo report OpenGL 3.3. I am aware that glxinfo may report the wrong version numbers as per the Mesa 10.1 Release Notes, however the rendering engine I'm trying to run fails because of this.
I use the following code to spawn a window:
glfwOpenWindowHint(GLFW_OPENGL_VERSION_MAJOR, 3);
glfwOpenWindowHint(GLFW_OPENGL_VERSION_MINOR, 3);
glfwOpenWindowHint(GLFW_OPENGL_PROFILE, 0);
if(GL_TRUE != glfwOpenWindow(
_windowDimensions.x, _windowDimensions.y,
0, 0, 0, 0, 32, 0, GLFW_WINDOW))
{
THROW("GLFW error: failed to create window.");
}
When I try to run the rendering engine using this setup, the above exception gets thrown as OpenGL 3.3 is not supported. I can set GLFW_OPENGL_VERSION_MINOR to 0 and then the window opens fine, but an exception will be thrown later as GLSL 3.3 shaders are required.
Also note that the rendering engine runs fine when I use the proprietary fglrx drivers (and then glxinfo reports OpenGL version 4.2), so the application itself really is not the problem, but the supported OpenGL is.
So what am I doing wrong? Why doesn't Mesa 10.1 support OpenGL 3.3 for me? My graphics card certainly supports it.
Here's some additional information that may be useful.

What they do not tell you, but indirectly imply ("Some drivers don't support all the features required in OpenGL 3.3."), is that in the last official release of Mesa (10.0), GL 3.3 only works on Intel hardware. This is one of the joys of Intel's close involvement with the Mesa project. If you want reliable GL 3.3 support in any form on AMD hardware, you should use fglrx (the proprietary AMD driver) for the time being.
The development release of Mesa 10.1 may implement GL 3.3 on radeon drivers, but you need to request a 3.3 core profile. You are not doing this currently.
This:
glfwOpenWindowHint(GLFW_OPENGL_PROFILE, 0);
Actually needs to be this:
glfwOpenWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);
Also, there is no such thing as a GL 3.0 compatibility profile or 3.1 core profile. Profiles were not introduced into OpenGL until 3.2. There is a concept of GL_ARB_compatibility in GL 3.1, but that is not the same thing as a profile; glxinfo is giving misleading information.
I answered the thread OP mentions regarding "OpenGL & GLSL 3.3 on an HD Graphics 4000 under Ubuntu 12.04" but I thought I would give the same answer here too considering info seems so scarce. This works for those using freeglut and glew: so Ive seen a lot of threads surrounding this and I thought here would be a good place to respond. Im running Ubuntu 15.04 with intel ivybridge. After using the "Intel Graphics installer for linux" application, glxinfo gives the following info regarding openGl: OpenGL core profile version string: 3.3 (Core Profile) Mesa 10.6.0 OpenGL core profile shading language version string: 3.30 OpenGL version string: 3.0 Mesa 10.6.0 OpenGL shading language version string: 1.30 Now from this you can see that the core profile and glsl version are 3.3,but compatible openGl is only 3.0 thus if you want your code to run with 3.3 you need to specify both an opengl core profile and a glsl core profile. The following steps should work if youre using freeglut and glew: -the glsl #version should specify that you want the core profile: #version 330 core -specify you want opengl 3.3: glutInitContextVersion (3, 3); -and finally set glewExperimental to true before glewInit(): glewExperimental = GL_TRUE; hope this helps some people get started :)
