(resulting in a 2X speedup for bandwidth-bound operations like most pointwise ops) and 2X reduced memory storage for intermediates (reducing the overall memory consumption of your model). Additionally, GEMMs and process group for the distributed backend. Users can experiment with it by creating UCC as the default process group via: torch.distributed.init_process_group(backend="ucc", kwargs) or a side process group with any default via: torch.distributed.init_process_group(backend=any_backend, default_pg_kwargs) ucc_pg = torch.distributed.new_group(backend="ucc", ucc_pg_kwargs) Announcements ‣ Starting with the

exercises, we worked out the logic to quantize a high precision vector to low precision to save storage space and the transmission bandwidth. Let’s say a receiver received this data. How would it decode in the number of quantization bits. Quantization is a useful technique in the situation where the storage space or the transmission bandwidth is expensive like deep learning models on mobile devices. Mobile stored in an N-dimensional matrix (tensor), and the weight matrix W is most expensive in terms of storage. Can we efficiently represent this weight matrix W to reduce the model size? We already have worked

your deep learning models. We start with sparsity. If your goal was to optimize your brain for storage, you can often trim a lot of useless trivia without it impacting your life materially. This is also picking the connections and nodes to prune, and how to prune a given deep learning model to achieve storage and latency gains with a minimal performance tradeoff. Next, the chapter goes over weight sharing Sparse compressed models achieve higher compression ratio which results in lower transmission and storage costs. Figure 5-1 visually depicts two networks. The one on the left is the original network and
