要使用混合精度,您需要在创建加速器对象时,将mixed_precision参数设置为true。这样,accelerator库将自动使用较低精度的数字来存储模型参数和梯度。 以下是使用混合精度设置加速器对象的示例代码: ```scss #include <accelerator/accelerator.h> int main() { // 创建加速器对象并设置混合精度 auto accelerator_obj =...
The multipliers in each multiplier unit receive different combinations of the MSNs and the LSNs of the multiplicands. The multiplication unit and the adder can provide mixed-precision dot-product computations.

When using mixed precision, we add `pad_to_multiple_of=8` to pad all tensors to multiple # of 8s, which will enable the use of Tensor Cores on NVIDIA hardware with compute capability >= 7.5 (Volta). data_collator = DataCollatorWithPadding(tokenizer, pad_to_multiple_of=(8 if ...
AI applications involve complex algorithms that include billions to trillions of parameters and require integer and floating-point multidimensional matrix mathematics at mixed precision ranging from 4-bits to 64-bits. Although the underlying mathematics consists of simple multipliers and adders, they are ...
