因此,一些 GPU 厂商(不是只有 NVIDIA 一家这么做)将将多个 DDR 芯片堆叠之后与 GPU 芯片封装到一起(后文讲到 H100 时有图),这样每片 GPU 和它自己的显存交互时,就不用再去 PCIe 交换芯片绕一圈,速度最高可以提升一个量级。 这种“高带宽内存”(High Bandwidth Memory)缩写就是 HBM。 现在CPU 也有用 HB...

When training large models, you might notice high usage of shared GPU memory in Task Manager: This is normal. TensorFlow-DirectML uses shared GPU memory as a staging area for upload and readback of tensor data to and from the GPU. Because of this, some increase in shared GPU memory utiliza...

A complete computer vision algorithm can be created by implementing sequences of these filtering operations. After the texture has been filtered by the fragment program, the resulting image is placed into texture memory, either by using render-to-texture extensions or by copying the frame buffer ...
With full systems and core systems available, direct water cooling removes heat from key components – including power supplies – for completely fanless operation. Liquid-assisted cooling With either a thermal transfer module (TTM) or liquid-to-air heat exchanger (L2A), traditional air-cooled syste...
(SIMD) architecture. Given that the GPU can outperform the CPU both for memory-bound and compute-bound algorithms, finding ways to sort efficiently on the GPU is important. Furthermore, because reading back data from the GPU to the CPU to perform operations such as sorting is inefficient,...
In its original form, the LiFE algorithm suffered from a few key drawbacks, which needed to be overcome to enable connectome evaluation at scale. First, a CPU implementation of the memory-efficient implementation of the LiFE algorithm still suffered from computational bottlenecks, because every iterat...
