Fairseq bfloat16 vs float16 speed
Did you know?
WebOct 1, 2024 · bfloat16 is generally easier to use, because it works as a drop-in replacement for float32. If your code doesn't create nan/inf numbers or turn a non-0 into a 0 with float32, then it shouldn't do it with bfloat16 either, roughly speaking. So, if your … Web@register_optimizer ("adam", dataclass = FairseqAdamConfig) class FairseqAdam (FairseqOptimizer): """Adam optimizer for fairseq. Important note: this optimizer corresponds to the "AdamW" variant of Adam in its weight decay behavior.
WebJan 9, 2024 · In TensorFlow, there are two 16bit floating point types: float16 and bfloat16. Float16 follows the IEEE standard for half precision floating point numbers, where in comparison to float32, the exponent is represented with 5bit instead of 8bit and the mantissa with 10bit instead of 23bit. WebApr 5, 2024 · When using intrinsics directly conventional wisdom (see this 2024 paper discussing half vs. half2 performance) seems to say that bfloat162 will offer better performance over using bfloat16 unless the compiler has learned lots of new tricks. But I am not aware if we actually use that a lot in PyTorch.

Is it expected or not?
WebJan 10, 2024 · bfloat16 will continue to be a thing, but it's really a compressed representation of Float, rather than its own format. In particular, any arithmetic on bfloat16 values (if those operators exist at all) should produce Float results, while arithmetic on Float16 will produce Float16 results. 5 Likes
