所以,我们需要利用到tensor core来加速FFT的运算。幸运的是,我们可以利用经典的Cooley-Tukey算法来将FFT的计算分解成一系列smaller block-level的矩阵相乘的运算来充分利用tensor core。 So we need some way to take advantage of the tensor cores on GPU. Luckily, there’s a classic algorithm called the Coole...
对Dense 卷积而言,一种通用优化计算手段就是 im2col/implicit GEMM。由于其太经典了我们在这里不再赘述 im2col 的过程,感兴趣的可以翻阅我们之前写的文章《MegEngine TensorCore 卷积算子实现原理》: https://zhuanlan.zhihu.com/p/372973726 。在经过了 im2col 变换之后,我们就成功的将卷积转换成了矩阵乘的形式。其...
在能效方面,相比于未使用 NVIDIA GPU 的其他TOP500 系统的平均能效表现,Selene 的能效高出了 6.8 倍。Selene 的优异性能和能效均要归功于 NVIDIA A100 GPU 中的第三代 Tensor Core 核心。该核心可以为传统的 64 位数学模拟及精度较低的 AI 工作提供加速。 目前,这些超级计算机已经用到了气候预测、交通、地震预...
When I pass torch.fft.irfftn/hfftn/ihfftn a tensor with a shape larger than two dimensions, and the shape value is too large, the code triggers Aborted (core dumped) and outputs "malloc(): corrupted top size ", which seems to corrupt the heap. Here is an example: import torch inpu...

Tensor productThis paper presents an area-efficient variable-length FFT algorithm for DVB-T2 receivers. A matrix-based approach is used to achieve a novel radix 28 algorithm that fulfils the DVB-T2 specifications. Several implementation techniques are proposed to apply in order to reduce the FFT ...
Based on fast linear binning approximation and Fourier-based fast convolution, the multivariate kernel density derivative estimation (KDDE) was proposed to compute the probability values of Euler solutions derived from tensor gravity data using tensor Euler deconvolution. The algorithm is an extension of...
