What is Tensor Parallelism?
&lt;|end|&gt;&lt;|start|&gt;assistant&lt;|channel|&gt;analysis&lt;|message|&gt;Need to explain tensor parallelism.&lt;|end|&gt;&lt;|start|&gt;assistant&lt;|channel|&gt;final&lt;|message|&gt;**Tensor Parallelism** is a technique used to distribute the computation of a single tensor (or a set of tensors) across multiple devices (GPUs, TPUs, or other accelerators) in order to speed up large‑scale deep‑learning training and inference. It is one of several parallelism strategies—alongside data parallelism, pipeline parallelism, and model parallelism—designed to scale models that exceed the memory or compute capacity of a single device.

## 1. Why Tensor Parallelism?
- **Memory constraints**: Modern

OOM during forward/backward pass: CUDA out of memory. Tried to allocate 508.00 MiB. GPU 2 has a total capacity of 22.30 GiB of which 118.69 MiB is free. Process 25557 has 22.18 GiB memory in use. Of the allocated memory 21.52 GiB is allocated by PyTorch, and 357.89 MiB is reserved by PyTorch but unallocated. If reserved but unallocated memory is large try setting PYTORCH_CUDA_ALLOC_CONF=expandable_segments:True to avoid fragmentation.
