using minifloat (8-bit float) to explain floating number concepts (scale, overflow, etc.). Floating arithmetic blocks don't have the 8-bit option, eg: addition, multiplication, subtraction, etc., and for me it would be very useful. Would it be possible to implement 8-bit float ...

Shifted and Squeezed 8-bit Floating Point format for Low-Precision Training of Deep Neural Networks Here we introduce a novel methodology for training deep neural networks using 8-bit floating point (FP8) numbers. Reduced bit precision allows for a ... L Cambier,A Bhiwandiwalla,T Gong,... ...
模型的内存需求要考虑两点,模型参数量、参数精度。一般参数精度有float32、float16、bfloat16三种,如下图https://blogs.nvidia.com/blog/2020/05/14/tensorfloat-32-precision-format/ Float32(FP32)表示标准IEEE 32-bit floating point,这个数据类型代表了范围较宽的浮点数字。在FP32中,8位表示幂数,23位表示系...
We present a simple and computationally efficient quantization scheme that enables us to reduce the resolution of theparametersof a neural network from 32-bit floating point values to 8-bit integer values. The proposed quantization scheme leads to significant memory savings and enables the use of op...
16-bit “bfloat” (BFP16) This floating point format was developed by the Google Brain team, and it is specially designed for machine learning (and “B” in its name also stands for “brain”). This type is a modification of the “standard” 16-bit float: the exponent was enlarg...
Transformer Engine (TE) is a library for accelerating Transformer models on NVIDIA GPUs, including using 8-bit floating point (FP8) precision on Hopper GPUs, to provide better performance with lower memory utilization in both training and inference. TE provides a collection of highly optimized build...

The color components of an 8-bit RGB image are integers in the range [0, 255] rather than floating-point values in the range [0, 1]. A pixel whose color components are (255,255,255) is displayed as white. The image command displays an RGB image correctly whether its class is double...
