Click the Options button on the toolbar, then Customize Rank E... How do I turn off chart animation? By default charts (bars, graphs, etc.) animate as there is more information to be displayed than space on small screens; by cycling we can display more information. You can turn it off by clickin... GPGPU / Graphics (OpenCL, CUDA, DirectX CS, Vulkan, etc.) support In order to run the graphics (GPGPU) modules and benchmarks, your system must meet the hardware and software requirements: Sandra: Sandra Platinum/2017 and later: support OpenCL 2.x, DirectX Compu... GFX / Video (OpenGL, DirectX, Vulkan, etc) support In order to run the video (graphics) modules and benchmarks, your system must meet the hardware and software requirements: For ALL operating systems - you need the latest DirectX. Download DirectX... DirectX Compute Shader/DirectCompute While it should be easier to get DirectX ComputeShader working than OpenCL in Windows, as it is part of DirectX, it may actually be more complicated: Windows 7 is set. Windows Vista requires t... How to enable large/huge memory pages in Windows Under Windows, huge pages (1GB) are not supported - yet! To use large pages (2-4MB) pages you specifically need to give your user the "lock pages in memory" privilege using Local Security Policy.... Cannot run Write Hard Disk Benchmark The Physical Disk benchmark accesses the disk directly thus is partition/volume/file system independent. As the writing (like the reading) is done at various positions on the disk (some random) i... OpenCL and Compute Shader on ATI/AMD GPUs in Sandra ATI/AMD has put together a KB article on the steps required to get this working: KB75 - Tips and suggestions for running SiSoftware Sandra 201X OpenCL GPGPU benchmarks with AMD/ATI Stream SDK v2.... Media Transcode Benchmark and hardware acceleration This benchmark requires Windows 7 (and later) as it contains Media Foundation transcode (MFT) support. Unfortunately older versions of Windows do not contain API that allows 3-rd party software to use... AVX, AVX2/FMA, AVX512, etc. SIMD benchmarks do not run! Operating System support is required to save/restore extended SIMD state - and thus use these SIMD instruction sets AVX, AVX2/FMA, AVX512*, etc. You need Windows 7 SP1/Server 2008 R2 SP1 or later to ... How do I share my scores (benchmark results) with other people? There are many ways to do this: Enable Ranking and create an account. Submit your results by benchmarking your computer and then ask your friends to search for your results through "Database To... What compiler(s) and optimisations are used by the Sandra Benchmarks? * Sandra 2011/2010 use ONLY the Visual Studio 2008/SP1 compiler (15.xx) and MASM/YASM for the assembler code. We use blended optimisation optimised for speed (O2). * Sandra 2009 uses ONLY the Visua... Running Tests and Benchmarks on Remote Computers Please see this detailed article on how to configure Sandra on remote computer and how to connect to it: http://www.sisoftware.co.uk/?d=qa&f=remote Hyper-V and AVX, AVX2, FMA3, FMA4, etc. instruction sets Currently, the latest version of Hyper-V (e.g. in Windows 8, Windows Server 2012) does not enable OSXSAVE to save/restore the new CPU state supporting 256-bit registers. Thus, AVX, AVX2 or FMA3, FM... AVX, AVX2/FMA, AVX512, etc. need OS & VM / Hypervisor support Note that an operating system (OS) needs to support the new extended CPU state (OS-XSAVE) to allow software to use new instruction sets like AVX, AVX2/FMA, AVX512*, etc. Windows 7, 8.x, 10.x or later... Do Sandra's Scientific CPU benchmarks use any 3-rd party libraries? No, no proprietary libraries (e.g. Intel MKL, FFTW, etc.) are used nor included/required. Why? This way we have full control over the implementation, optimisations and all code paths (i.e. SSE2/AVX... Do Sandra's Scientific GP (GPU/APU) benchmarks use any 3-rd party libraries? No, no proprietary libraries (e.g. nV cuBLAS, cuFFT; AMD APPML, clMath etc.) are used nor included/required. Why? This way we have full control over the implementation, optimisations and all code ...
