CUDA on non-nVidia card hardware

My laptop doesn't have any nVidia graphic cards. I want to work on CUDA. The website says that CUDA can be worked in emulation mode on non-cuda hardware too. But when I tried installing CUDA drivers downloaded from their website, it gives an error "The nvidia setup couldn't locate any drivers that are compatible with yoour current hardwa...

glDrawElements flicker and crash

I'm getting a fishy error when using glDrawElements(). I'm trying to render simple primitives (mainly rectangles) to speed up drawing of text and so forth, but when I call glDrawElements() the WHOLE screen blinks black (not just my window area) for one frame or so. The next frame it turns back to the same "Windows colors" as before. And ...

Does GPL code linking with proprietary library depend which is created first?

Microsoft creates their windows and MFC DLL library, etc. An open source develop write a new MFC application and release the source code as GPL. The app has to link with the MS DLL/libraries to run in Windows, but I don't think anyone can argue that we now have the right to force the Microsoft's GPL their DLL. Does this mean the GPL...

How do I see the commands that are run by GNU make?

I'm trying to debug a complex Makefile. How do you get GNU make to print all the commands it runs? I couldn't find the answer in the man page (using the -d flag doesn't seem to print it). (This isn't necessary info to answer my question, but in case you're wondering: I'm having trouble compiling a project built on NVIDIA's CUDA library...

In .NET 3.5 C#, is there a way to detect if NVIDIA SLI mode is active

For NVIDIA graphics cards, you can have two working as one (SLI). For a .NET desktop application, I need to be able to check that SLI is enabled. Is this possible? ...

calculate the degree between two triangles in ansi c cuda

hi wanted to calculate the degreee between two triangles where every point of them has a 3d coordinate.... i.e. triangle 1: point1(x1,y1,z1), point2(x2,y2,z2), point3(x3,y3,z3). triangle 2: point1(x1,y1,z1), point2(x2,y2,z2), point4(x4,y4,z4). yes, the triangles always share exactly same two points. is there a way to calculate the degr...

Matlab GPU acceleration for loading large point cloud dataset

I'm trying to load a large dataset of a million points in 3d space in MATLAB, but whenever I try to plot it (scatter or plot3) , it takes forever. This is on a laptop with Intel Graphics Media Accelerator 950, up to 224-MB shared system memory. This also sometimes leads to Matlab 2008a crashing. Is there a way to let MATLAB use a Nvidia ...

Good source to learn about the differences between ATI and NVIDIA in OpenGL rendering?

The more i learn about OpenGL, the more problems i find! All i need is a list of the most common problems between ATI/NVIDIA cards, with solutions. So where is this magical source? ...

nvidia cuda using all cores of the machine

hi i was running cuda program on a machine which has cpu with four cores, how is it possible to change cuda c program to use all four cores and all gpu's available? i mean my program also does things on host side before computing on gpus'... thanks! ...

Can I use openCL in a application that I distribute to non developper machine?

I recently started to learn how to use openCL to speed up some part of my code. So far the speed gain is impressive. In one case the code ran up to 50X faster than on the CPU. However I wonder if can start using this code in a production environnement. The reason is that the first time that I tried to run the example code, nothing worked...

NVidia videocards - getting statistic

Hello, i need to write few applications about lowlevel videocard controling for my coursework. For example - temperature, working SM's, managing access to them, etc. OS linux, tesla c1060. Could you give me few advices where to search this kind of information? CUDA does not provide these features. It must be some work with dev\nvidia*...

Why is X11 Composite extension incompatible with Stereo visuals?

In the NVIDIA README for the Quadro card X driver, there is this comment: Workstation overlays, stereo visuals, and the unified back buffer (UBB) are incompatible with Composite. These features will be automatically disabled when Composite is detected Is there some fundamental X reason why this is so? Why are quadro cards ...

Force windows video driver reload. Is it possible at all?

Hi there, Some drivers use parameters written in the registry to configure themselves when they get loaded at boot time. I can modify those values and then reboot, but I would like to know if it is possible to force the driver reload, making the changes effective without rebooting. Specifically, I am talking about the video driver (nvi...

NVIDIA GPUs and PhysX engine

How is the NVIDIA PhysX engine implemented in the NVIDIA GPUs: It's a co-processor or the physical algorithms are implemented as fragment programs to be executed in the GPU pipeline ? ...

OpenCL support for Nvidia GTX 295

Hello, Does OpenCL support for Nvidia GTX 295 exists for Linux or is expected in the near future? TIA, -S ...

Counting FLOPS/GFLOPS in program - CUDA

Already finished my application which multiplies CRS matrix and vector (SpMV) and the only thing to do now is to count FLOPS my application did. In my opinion it's really hard to estimate number of floating point operation in case of sparse matrix - vector multiplication, because the number of multiplies in one row is really "jumpy" or f...

Compiling NVIDIA's Quadro FX SDK (NVGVOSDK) on Windows XP

Hi, I've got an NVIDIA Quadro FX 4800 card hooked up in a Windows XP box and I am trying to compile and run some code using the NVGVOSDK. This SDK is not very well documented and is rather old. I downloaded version 1.2 from the NVIDIA Partners site which is from 2007 but appears to be the latest version. I am trying to compile and run...

How to repackage NVIDIA .run drivers into .deb with DKMS

At present, Ubuntu offers the 195.36.24 drivers as nvidia-current in their repository. This packaged driver is pretty cool as it uses DKMS so you don't have to keep reinstalling the driver after a new kernel version. The NVIDIA .run package drivers are at version 257 (beta) but they don't use DKMS so the graphics screws up every time a ...
