    NMath Premium是在.NET平臺(tái)上將GPU加速數(shù)學(xué)計(jì)算的強(qiáng)大CUDA架構(gòu)的優(yōu)勢利用到NMathNMath Stats中。CUDA是NVIDIA開發(fā)的一種并行計(jì)算平臺(tái)和編程模型,它可以通過利用圖形處理單元的能力大幅提高計(jì)算性能。GPU計(jì)算是所有NVIDIA 8系列和更高級別的GPU中的一個(gè)標(biāo)準(zhǔn)功能。整個(gè)NVIDIA Tesla線均支持CUDA技術(shù)。

    NMath Stats 已與NMath標(biāo)準(zhǔn)版打包,最新版本請點(diǎn)擊跳轉(zhuǎn)下載

    Easy to Use

    NMath Premium works with any CUDA-enabled GPU. NMath Premium automatically detects the presence of a CUDA-enabled GPU at runtime and seamlessly redirects appropriate computations to it. The library can be configured to specify which problems should be solved by the GPU, and which by the CPU. If a GPU is not present at runtime, the computation automatically falls back to the CPU without error.

    No GPU programming experience is required.

    With a few minor exceptions, such as optional GPU configuration settings, the API is identical between NMath and NMath Premium. Existing NMath developers can simply upgrade to NMath Premium and immediately begin to offer their users higher performance from current graphics cards, or from additional GPUs, without writing any new software.

    No changes are required to existing NMath code.

    Supported Features

    GPU acceleration provides a 2-4x speed-up for many NMath functions. With large data sets running on high-performance GPUs, the speed-up can exceed 10x. Furthermore, off-loading computation to the GPU frees up the CPU for additional processing tasks, a further performance gain.

    The directly supported features for GPU acceleration of linear algebra (dense systems) are:

    • Singular value decomposition (SVD)

    • QR decomposition

    • Eigenvalue routines

    • Solve Ax = B

    GPU acceleration for signal processing includes:

    • 1D Fast Fourier Transforms (Complex data input)

    • 2D Fast Fourier Transforms (Complex data input)

    GPU: (1) NVIDIA Tesla M2090: 1 Fermi GPU, 512 CUDA cores, 6GB GDDR5 memory
    CPU: Intel Xeon X5670, 2.93 GHz, 6-core with Hyper-Threading (12 threads), 12 MB L3 cache, 32 nm manufacturing process (Westmere)

    Of course, many higher-level NMath and NMath Stats classes make use of these functions internally, and so also benefit from GPU acceleration indirectly.
