Last but not least, this is the performance of different levels of LP with varying sequence lengths and batch_size=1. All our experiments were done on 2x A100 SXM4 80Gb
(9/N)

Additionally, we show that some of the performance can be recovered through some very light fine-tuning of the parallel layers!

... and evaluate the best models on well-known benchmarks. We find that Llama 2 7B can have its effective depth reduced from 32->25 and Llama 3.2 3B from 28->23 without major accuracy losses.

We ablate the perplexity of Llama 2 7B and 3.2 3B on a subset of RedPajama wrt. the position and length (Δ) of LP...

Enter Tensor Parallelism (TP). By combining TP and LP, we can shard the original model across different devices, and the effective depth on each shard will be decreased thanks to LP.

We introduce Layer Parallelism (LP), a method that modifies the sequential computational graph of 2 consecutive layers to run them in parallel as shown in the picture. But naively running the new computational graph on a single GPU will not result in any speed-up.
(3/N)

We try to modify the computational graph of a trained Llama 2 7B using different transformations, and find that running pairs of layers in parallel does not result in a catastrophic perplexity increase, especially on later layers.
