Frequently Asked Questions V. Change Log -------------------------------------------------------------------------------- -------------------------------------------------------------------------------- I. (a) Windows Installation Instructions -------------------------------------------------------------------------------- 0. CUDA 2.3 Toolkit requires at least version 190.38 of the Windows Vista or Windows XP NVIDIA Display Driver. See the NVIDIA CUDA Toolkit 2.3 release notes for more detailed information. Please make sure to read the Driver Installation Hints Document before you install the driver: http://www.nvidia.com/object/driver_installation_hints.html 1. Uninstall any previous versions of the NVIDIA CUDA Toolkit and NVIDIA GPU Computing SDK. You can uninstall the NVIDIA CUDA Toolkit through the Start menu: Start menu->All Programs->NVIDIA Corporation->CUDA Toolkit->Uninstall CUDA You can uninstall the NVIDIA GPU Computing SDK through the Start menu: Start menu->All Programs->NVIDIA Corporation ->NVIDIA GPU Computing SDK->Uninstall NVIDIA GPU Computing SDK 2. Install version 2.3 of the NVIDIA CUDA Toolkit by running cudatoolkit_2.3_Win_[32|64].exe corresponding to your operating system. 3. Install version 2.3 of the NVIDIA GPU Computing SDK by running gpucomputingsdk_2.3_Win_[32|64].exe corresponding to your operating system. 4. Build the 32-bit and/or 64-bit, release, debug, emurelease, and/or emudebug configurations of the SDK project examples using the provided *.sln solution files for Microsoft Visual Studio 2005 or *_vc90.sln solution files for Microsoft Visual Studio 2008 You can: - either use the solution files located in each of the examples' directories in "NVIDIA GPU Computing SDK\C\src", - or use the global solution files release.sln or release_vc90.sln located in "NVIDIA GPU Computing SDK\C\src". Notes: - The simpleD3D9 example requires to have a Direct3D SDK installed and the VC++ directory paths (located in Tools->Options...) properly setup. - Most samples link to a utility library called "cutil" whose source code is in "NVIDIA GPU Computing SDK\C\common". The release and emurelease versions of these samples link to cutil[32|64].lib and dynamically load cutil[32|64].dll. The debug and emudebug versions of these samples link to cutil[32D|64D].lib and dynamically load cutil[32D|64D].dll. To build the 32-bit and/or 64-bit, release and/or debug configurations of the cutil library, use the solution files located in "NVIDIA GPU Computing SDK\C\common". The output of the compilation goes to "NVIDIA GPU Computing SDK\C\common\lib": - cutil[32|64].lib and cutil[32D|64D].lib are the release and debug import libraries, - cutil[32|64].dll and cutil[32D|64D].dll are the release and debug dynamic-link libraries, which get also copied to "NVIDIA GPU Computing SDK\C\bin\win[32|64]\[release|emurelease]" and "NVIDIA GPU Computing SDK\C\bin\win[32|64]\[debug|emudebug]" respectively; 5. Run the examples from the release, debug, emurelease, or emudebug directories located in "NVIDIA GPU Computing SDK\C\bin\win[32|64]\[release|debug|emurelease|emudebug]". Notes: - The release and debug configurations require a CUDA-capable GPU to run properly (see Appendix A.1 of the CUDA Programming Guide for a complete list of CUDA-capable GPUs). - The emurelease and emudebug configurations run in device emulation mode, and therefore do not require a CUDA-capable GPU to run properly. -------------------------------------------------------------------------------- I. (b) Linux Installation Instructions -------------------------------------------------------------------------------- [Part 1/2] Note: The default installation folder is "~/NVIDIA_GPU_Computing_SDK" For more detailed instructions, see section II below. 0. Install the NVIDIA Linux display driver by executing the file a. For 32-bit linux distributions use: cudadriver_2.3_linux_32_190.18.run b. For 64-bit linux distributions use: cudadriver_2.3_linux_64_190.18.run For information on installing NVIDIA Linux display drivers, please refer to the NVIDIA Accelerated Linux Driver Set README and Installation Guide: http://us.download.nvidia.com/XFree86/Linux-x86/1.0-9755/README/index.html 1. Install version 2.3 of the NVIDIA Toolkit by executing the file cudatoolkit_2.3_linux_*.run where * corresponds to your Linux distribution Add the CUDA binaries and lib path to your PATH and LD_LIBRARY_PATH environment variables. 2. Install version 2.3 of the NVIDIA GPU Computing SDK by executing the file gpucomputingsdk_2.3_linux.run The installer will prompt you to enter an installation path for the SDK or accept the default. We will refer to the path you choose as SDK_INSTALL_PATH. 3. Build the SDK project examples. cd /C make Note Adding the following in make will build for specific targets make x86_64=1 (for 64-bit targets) make i386=1 (for 32-bit targets) 4. Run the examples (32-bit or 64-bit Linux) cd /C/bin/linux/release matrixmul (or any of the other executables in that directory) See the next section for more details on installing, building, and running SDK samples. [Part 2/2] Note: The default installation folder is "~/NVIDIA_GPU_Computing_SDK" This package consists of a ".run" file. This is a self-extracting archive that decompresses its contents to a temporary folder and then installs the contents to a path that you specify. The archive is: gpucomputingsdk_2.3-linux.run: NVIDIA GPU Computing SDK Installer In addition, a NVIDIA Linux Display driver is needed to run CUDA code on an NVIDIA GPU. CUDA 2.3 requires version 190 or newer version of the linux NVIDIA Display Driver. Please see the NVIDIA CUDA Toolkit 2.3 release notes for more details. For information on installing NVIDIA Linux display drivers, please refer to the NVIDIA Accelerated Linux Driver Set README and Installation Guide: http://us.download.nvidia.com/XFree86/Linux-x86/1.0-9755/README/index.html 1. Install version 2.3 of the NVIDIA CUDA Toolkit by executing the file cudatoolkit_2.3_linux_*.run where * corresponds to your Linux distribution To install, run the cudatoolkit_2.3_linux_*.run script. You will be prompted for the path to where you want to put the CUDA files. In the following we will call this path . It is recommended that you run the installer as root and use the default install path (/usr/local). Make sure that you add the location of the CUDA binaries (such as nvcc) to your PATH environment variable and the location of the CUDA libraries (such as libcuda.so) to your LD_LIBRARY_PATH environment variable. In the bash shell, one way to do this is to add the following lines to the file ~/.bash_profile from your home directory. a. For 32-bit operating systems use the following paths PATH=$PATH:/bin LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/lib b. For 64-bit operating systems use the following paths PATH=$PATH:/bin LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/lib64 Then to export the environment variables add this to the profile configuration export PATH export LD_LIBRARY_PATH 2. Install the NVIDIA GPU Computing SDK by executing the file gpucomputingsdk_2.3_linux.run To install, run the gpucomputingsdk_2.3_linux.run script. You will be prompted for the path to where you want to put the CUDA SDK. You can regard the CUDA SDK as user code (it is a set of examples), and therefore the default installation is in the current user's home directory (~/NVIDIA_GPU_Computing_SDK). You must either accept the default or specify a path to which the user has write permissions. We will refer to the path you choose as SDK_INSTALL_PATH below. 3. Build the SDK project examples. a. cd /C b. Build: - release configuration by typing "make". - debug configuration by typing "make dbg=1". - emurelease configuration by typing "make emu=1". - emudebug configuration by typing "make emu=1 dbg=1". - x86_64=1 configuration by typing "make x86_64=1" - i386=1 configuration by typing "make i386=1" Running make at the top level first builds libcutil, a utility library used by the SDK examples (libcutil is simply for convenience -- it is not a part of CUDA and is not required for your own CUDA programs). Make then builds each of the projects in the SDK. NOTES: - The release and debug configurations require a CUDA-capable GPU to run properly (see Appendix A.1 of the CUDA Programming Guide for a complete list of CUDA-capable GPUs). - The emurelease and emudebug configurations run in device emulation mode, and therefore do not require a CUDA-capable GPU to run properly. - You can build an individual sample by typing "make" (or "make emu=1", etc.) in that sample's project directory. For example: cd /C/src/matrixMul make emu=1 And then execute the sample with: /C/bin/linux/emurelease/matrixMul - To build just libcutil, type "make" (or "make dbg=1") in the "common" subdirectory: cd /C/common make 4. Run the examples from the release, debug, emurelease, or emudebug directories located in /C/bin/linux/[release|debug|emurelease|emudebug]. -------------------------------------------------------------------------------- I. (c) Mac OSX Installation Instructions -------------------------------------------------------------------------------- [Part 1/2] For more detailed instructions, see part 2 of this section below.

(a) Known Issues on CUDA SDK for Windows -------------------------------------------------------------------------------- Note: Please see the CUDA Toolkit release notes for additional issues. 1. In code sample alignedTypes, the following aligned type does not provide maximum throughput because of a compiler bug: typedef struct __align__(16) { unsigned int r, g, b; } RGB32; The workaround is to use the following type instead: typedef struct __align__(16) { unsigned int r, g, b, a; } RGBA32; as illustrated in the sample. 2. Installing the "NVIDIA GPU Computing SDK" under Vista with UAC (User Access Control) enabled will not fail if the path is "Program Files\NVIDIA Corporation\NVIDIA GPU Computing SDK". By default, UAC is enabled for Vista. This prevents users from installing the SDK in the folder "Program Files". If UAC is disabled, the user is free to install the SDK in other folders. Before the CUDA 2.1, the SDK installations path would be under: "Program Files\NVIDIA Corporation\NVIDIA CUDA SDK". Starting with CUDA 2.1, the new default installation folder is: "Application Data\NVIDIA Corporation\NVIDIA CUDA SDK" residing under "All Users" or "Current". For NVIDIA GPU Computing 2.3, the SDK installations path would be under: "Program Files\NVIDIA Corporation\NVIDIA GPU Computing SDK". Starting with NVIDIA GPU Computing 2.3, the new default installation folder is: "Application Data\NVIDIA Corporation\NVIDIA GPU Computing SDK" residing under "All Users" or "Current". -------------------------------------------------------------------------------- III. (b) Known Issues on CUDA SDK for Linux -------------------------------------------------------------------------------- Note: Please see the CUDA Toolkit release notes for additional issues. 1. "ld: cannot find -lglut". On some linux installations (notably default RHEL 4 update 3 installations), building the simpleGL example (and other examples that use OpenGL) can result in a linking error like the following. /usr/bin/ld: cannot find -lglut Typically this is because the SDK makefiles look for libglut.so and not for variants of it (like libglut.so.3). To confirm this is the problem, simply run the following command. ls /usr/lib | grep glut You should see the following (or similar) output. lrwxrwxrwx 1 root root 16 Jan 9 14:06 libglut.so.3 -> libglut.so.3.8.0 -rwxr-xr-x 1 root root 164584 Aug 14 2004 libglut.so.3.8.0 If you have libglut.so.3 in /usr/lib, simply run the following command as root. ln -s /usr/lib/libglut.so.3 /usr/lib/libglut.so If you do NOT have libglut.so.3 then you can check whether the glut package is installed on your RHEL system with the following command. rpm -qa | grep glut You should see "freeglut-2.2.2-14" or similar in the output. If not, you or your system administrator should install the package "freeglut-2.2.2-14". Refer to the Red Hat and/or rpm documentation for instructions. If you have libglut.so.3 but you do not have write access to /usr/lib, you can also fix the problem by creating the soft link in a directory to which you have write permissions and then add that directory to the libarary search path (-L) in the Makefile. 2. In code sample alignedTypes, the following aligned type does not provide maximum throughput because of a compiler bug: typedef struct __align__(16) { unsigned int r, g, b; } RGB32; The workaround is to use the following type instead: typedef struct __align__(16) { unsigned int r, g, b, a; } RGBA32; as illustrated in the sample. 3. Some Linux distributions may not include the GLU library. You can download this from this search engine, matching the correct Linux distribution. http://fr.rpmfind.net/linux/rpm2html/search.php?query=libGLU.so.1&submit=Search+... 4. (SLED11) SUSE Linux Enterprise Edition 11 is missing: "libGLU", "libX11" "libXi", "libXm" This particular version of SUSE Linux 11 does not have the proper symbolic links for the following libraries: a. libGLU ls /usr/lib | grep GLU libGLU.so.1 libGLU.so.1.3.0370300 To create the proper symbolic links: ln -s /usr/lib/libGLU.so /usr/lib/libGLU.so.1 b. libX11 ls /usr/lib | grep X11 libX11.so.6 libX11.so.6.2.0 To create the proper symbolic links: ln -s /usr/lib/libX11.so.6 /usr/lib/libX11.so c. libXi ls /usr/lib | grep Xi libXi.so.6 libXi.so.6.0.0 To create the proper symbolic links: ln -s /usr/lib/libXi.so.6 /usr/lib/libXi.so d. libXm ls /usr/lib | grep Xm libXm.so.6 libXm.so.6.0.0 To create the proper symbolic links: ln -s /usr/lib/libXm.so.6 /usr/lib/libXm.so -------------------------------------------------------------------------------- III. (c) Known Issues on CUDA SDK for Mac OSX -------------------------------------------------------------------------------- Note: In addition, please look at the CUDA Toolkit release notes for additional issues. - Note on CUDA Mac 10.5.x (Leopard), CUDA applications can run in 32-bit. Support for 64-bit is not working, this will be addressed in a future update. This is a known issue and NVIDIA is working to resolve this issue soon. -------------------------------------------------------------------------------- IV. Frequently Asked Questions -------------------------------------------------------------------------------- The Official CUDA FAQ is available online on the NVIDIA CUDA Forums: http://forums.nvidia.com/index.php?showtopic=84440 Note: Please also see the CUDA Toolkit release notes for additional Frequently Asked Questions. -------------------------------------------------------------------------------- V. Change Log -------------------------------------------------------------------------------- Note: Unless noted specifically noted, the Release Logs are for all OS's. Release 2.3 (R190 Release Update) * New SDK Samples - vectorAdd, vectorAddDrv - Two samples (Runtime and Driver API) which implements element by element vector addition. These simple samples do not use the CUTIL library. [Linux SDK] * Support for Cross Compiliation - Adding the following during Make will build for specific targets x86_64=1 (for 64-bit targets) i386=1 (for 32-bit targets) - Note on Linux, the 190.18 or newer driver installs the necessary libcuda.so for both 32-bit and 64-bit targets. Release 2.3 * New Samples - 3DFD - 3D Finite Differentce sample demonstrates 3DFD stencil coputation on a regular grid. - matrixMulDynlinkJIT - Matrix Multiply sample that uses PTXJIT (inlined) and also supports dynamic linking to nvcuda.dll - bitonicSort has been renamed to sortingNetworks - histogram64 and histogram256 have been combined to a single project histogram Release 2.3 Beta * Added PTXJIT - New SDK sample that illustrates how to use cuModuleLoadDataEx - Loads a PTX source file from memory instead of file. * Windows SDK only - Changing the name NVIDIA CUDA SDK -> NVIDIA GPU Computing SDK - Added cudaDecodeD3D9 and cudaDecodeGL - NVCUVID now support for OpenGL interop, these two new SDK samples illustrates how to use NVCUVID to decode MPEG-2, VC-1, or H.264 content. - The samples show how to decode video and pass to D3D9 or OpenGL, however these samples do not display the decoded video frames. Release 2.2.1 [Windows SDK] * Updated Cuda.Rules files (no long uses -m32) to generate CUBIN/PTX output, * Cuda.rules option to generate PTX and to inline CUDA source with PTX generated assembly [Mac and Linux SDK] * Updated common.mk file to removed -m32 when generating CUBIN output * Support for PTX output has been added to common.mk [All SDK Packages] * CUDA Driver API samples: simpleTextureDrv, matrixMulDrv, and threadMigration have been updated to reflect changes: - Previously when compiling these CUDA SDK samples, gcc would generate a compilation error when building on a 64-bit Linux OS if the 32-bit glibc compatibility libraries were not previously installed. This SDK release addresses this problem. The CUDA Driver API samples have been modified and solve this problem by casting device pointers correctly before being passed to CUDA kernels. - When setting parameters for CUDA kernel functions, the address offset calculation is now properly aligned so that CUDA code and applications will be compatible on 32-bit and 64-bit Linux platforms. - The new CUDA Driver API samples by default build CUDA kernels with the output as PTX instead of CUBIN. The CUDA Driver API samples now use PTXJIT to load the CUDA kernels and launch them. * Added sample pitchLinearTexture that shows how to texture from pitch linear memory Release 2.2 Final [Windows and Linux SDK] * Supports CUDA Event Blocking Stream Synchronization (CU_CTX_BLOCKING_SYNC) on Linux and Windows [All SDK Packages] * Added Mandelbrot (Julia Set), deviceQueryDrv, radixSort, SobolQRNG, threadFenceReduction * New CUDA 2.2 capabilities: - supports zero-mem copy (GT200, MCP79) * simpleZeroCopy SDK sample - supports OS allocated pinned memory (write combined memory). Test this by: > bandwidthTest -memory=PINNED -wc Release 2.1 [Windows SDK] * Projects that depend on paramGL now build the paramGL source files instead of statically linking with paramGL*.lib. [All SDK Packages] * CUDA samples that use OpenGL interop now call cudaGLSetGLDevice after the GL context is created. This ensures that OpenGL/CUDA interop gets the best possible performance possible. * Bug fixes Release 2.1 Beta [Windows SDK] * Now supports Visual Studio 2008 projects, all samples also include VS2008 * Removed Visual Studio 2003.NET projects * Added Visual Studio CUDA.rules to support *.cu files. Most projects now use this rule with VS2005 and VS2008 projects. * Default CUDA SDK installation folder is under "All Users" or "Current User" in a sub-folder "Application Data\NVIDIA Corporation\NVIDIA GPU Computing SDK". See section "III. Known issues" for more details. [Mac and Linux SDK] * For CUDA samples that use the Driver API, you must install the Linux 32-bit compatibility (glibc) binaries on Linux 64-bit Platforms. See Known issues in about section IV on how to do this. [All SDK Packages] * Added CUDA smokeParticles (volumetric particle shadows samples) * Note: added cutil_inline.h for CUDA functions as an alternative to using the cutil.h macro definitions Release 2.0 Beta2 [Windows SDK] * 2 new code samples: cudaVideoDecode and simpleVoteIntrinsics Release 2.0 Beta [All SDK Packages] * Updated to the 2.0 CUDA Toolkit * CUT_DEVICE_INIT macro modified to take command line arguments. All samples now support specifying the CUDA device to run on from the command line (“-device=n”). * deviceQuery sample: Updated to query number of multiprocessors and overlap flag. * multiGPU sample: Renamed to simpleMultiGPU. * reduction, MonteCarlo, and binomialOptions samples: updated with optional double precision support for upcoming hardware. * simpleAtomics sample: Renamed to simpleAtomicIntrinsics. * 7 new code samples: dct8x8, quasirandomGenerator, recursiveGaussian, simpleD3D9Texture, simpleTexture3D, threadMigration, and volumeRender [Windows SDK] * simpleD3D sample: Renamed to simpleD3D9 and updated to the new Direct3D interoperability API. * fluidsD3D sample: Renamed to fluidsD3D9 and updated to the new Direct3D interoperability API. Release 1.1 * Updated to the 1.1 CUDA Toolkit * Removed isInteropSupported() from cutil: graphics interoperability now works on multi-GPU systems * MonteCarlo sample: Improved performance. Previously it was very fast for large numbers of paths and options, now it is also very fast for small- and medium-sized runs. * Transpose sample: updated kernel to use 2D shared memory array for clarity, and optimized bank conflicts. * 15 new code samples: asyncAPI, cudaOpenMP, eigenvalues, fastWalshTransform, histogram256, lineOfSight, Mandelbrot, marchingCubes, MonteCarloMultiGPU, nbody, oceanFFT, particles, reduction, simpleAtomics, and simpleStreams Release 1.0 * Added support for CUDA on the MAC * Updated to the 1.0 CUDA Toolkit. * Added 4 new code samples: convolutionTexture, convolutionFFT2D, histogram64, and SobelFilter. * All graphics interop samples now call the cutil library function isInteropSupported(), which returns false on machines with multiple CUDA GPUs, currently (see above). * When compiling in DEBUG mode, CU_SAFE_CALL() now calls cuCtxSynchronize() and CUDA_SAFE_CALL() and CUDA_CHECK_ERROR() now call cudaThreadSynchronize() in order to return meaningful errors. This means that performance might suffer in DEBUG mode. Release 0.9 * Updated to version 0.9 of the CUDA Toolkit. * Added 6 new code samples: MersenneTwister, MonteCarlo, imageDenoising, simpleTemplates, deviceQuery, alignedTypes, and convolutionSeparable. * Removed 3 old code samples: - vectorLoads and loadUByte replaced by alignedTypes; - convolution replaced by convolutionSeparable. Release 0.8.1 beta * Standardized project and file naming conventions. Several project names changed as a result. * cppIntegration output now matches the other samples ("Test PASSED"). * Modified transpose16 sample to transpose arbitrary matrices efficiently, and renamed it to transpose. * Added 11 new code samples: bandwidthTest, binomialOptions, BlackScholes, boxFilter, convolution, dxtc, fluidsGL, multiGPU, postProcessGL, simpleTextureDrv, and vectorLoads. Release 0.8 beta * First public release. -------------------------------------------------------------------------------- VII.
