Nvidia Cuda Emulator Driver Bugs In#

A chinese freelance developer has coded a means to get CUDA work as a middleware on OpenCL. NVIDIA's CUDA GPU compute API could be making its way to practically every PC, with an NVIDIA GPU in place, or not. NVIDIA CUDA Emulator for every PC.

To have the driver emulate features of GPUs newer than the one installed in your system, select the newer GPU generation from the 'Feature Set Emulation' menu. GPU core.Download NVemulate (.exe) Built:Sep 10 2014By default, the NVIDIA OpenGL driver will expose all features supported by the NVIDIA GPU installed in your system. CUDA-Z shows following information: Installed CUDA driver and dll version.

Writing Program Object SourceWhen the вЂњWrite Program Object SourceвЂќ box is checked, the driver outputs fsrc_%d_%d_%d.txt and vsrc_%d_%d_%d.txt files into the application's working directory when fragment and vertex shaders respectively are linked where the first %d represents the application's handle number for the linked program object, the second %d is the shader object handle, and the third %d is a unique integer representing this link instance. NVemulate Options to Aid DebuggingOther check boxes in the NVemulate control panel are designed to aid debugging of GLSL programs as well as help developers report GLSL issues so they can be readily addressed in future drivers. To target a GPU family newer than the GPU installed in your system, you will need to enable feature set emulation as described above. To have the compiler generate code targeting a different GPU family, select the entry for that family from the 'GLSL Compiler Device Support' menu. Controlling GLSL Support with NVemulateBy default, the OpenGL Shading Language (GLSL) compiler in the NVIDIA OpenGL driver will generate code targeting the NVIDIA GPU installed in your system.

Writing Program Object AssemblyWhen the вЂњWrite Program Object AssemblyвЂќ box is checked, the driver outputs fasm_%d_%d.txt and vasm_%d_%d.txt files into the application's working directory when fragment and vertex shaders respectively are linked where the first %d represents the application's handle number for the linked program object, and the second %d is a unique integer representing this link instance. If you still suspect an OpenGL driver bug, please send the source and assembly files. This is the actual GLSL source text that is compiled and linked.These files are generated whether or not the program object links successfully.Check that your source code text has been properly transferred to the driver.

If the assembly seems correct or it clearly does not correspond to your high-level shader source, please include the assembly output with your bug report. Sometimes you may find bugs in your own shader source code by seeing how the driver's Cg compiler technology translated your shader into assembly form. For example, assembly for shaders targeting the G80 family will use the NV_gpu_program4 family of languages.Before you submit a GLSL bug report to NVIDIA, double check that the assembly generated for your successfully linked program object matches what you expect. The assembly text conforms to one of the vertex or fragment program extensions depending on the shader type and hardware capabilities.

One way to get a вЂњsecond opinionвЂќ about the behavior of your application is to force software rasterization. Forcing Software RasterizationDriver bugs in GLSL programs may be due to the compiler translating your shader incorrectly into a GPU executable form or the problem may be a more basic driver bug. Version directives are already required to use any features added to the shading language in version 1.20 or higher. Additionally, portability warnings will always be treated as errors for any shader containing a '#version' directive. This behavior can be strengthened by checking the вЂњGenerate Shader Portability ErrorsвЂќ checkbox in NVemulate to turn those warnings into errors.

You are not using the built-in driver for NVIDIA hardware provided with Microsoft Windows, including ones installed via Windows Update. You are using an NVIDIA Quadro or GeForce GPU. NVemulate TroubleshootingIf you do not see changes from the NVemulate control panel taking effect, make sure of the following: However, if the results of hardware rendering and the software rasterizer do not match, that is an important clue as to the nature of a possible driver bug.Additionally, if the hardware rendering and the software rasterizer results match, you may want to review once more whether the problem lies with your shader source before reporting a bug. This is extremely slow, particularly when per-fragment programmability is involved.

Download NVemulate (.exe) Built: Jan 05 2007 Download NVemulate (.exe) Built: Aug 11 2008 Download NVemulate (.exe) Built: Jan 7 2011 To run NVemulate this way, right-click on the NVemulate executable and select 'Run as Administrator'.When you install a new NVIDIA graphics driver, the settings updated by NVemulate may be reset to their defaults, so you it may be necessary to re-run NVemulate after such an update. For NVIDIA driver versions 256 and higher, NVemulate must be run with elevated permissions on Windows Vista and Windows 7 systems.
