<h2>A Training Library: How Scaling Works</h2>
<ul>
<li>Accelerate’s DataLoaders and schedulers work off of a sharding mindset</li>
<li>Rather than repeating the same data across <code>n</code> nodes, we instead split it</li>
<li>Speeds up training linearly</li>
<li>Given a batch size of 16 on a single GPU, to recreate this across 8 GPUs you would use a batch size of 2</li>
<li>This also means the scheduler will be stepped <code>n</code> GPUs at a time per “global step”</li>
</ul>
</section>
<section id="a-training-library-mixed-precision" class="slide level2">
<h2>A Training Library: Mixed Precision</h2>
<ul>
<li>This may be a bit different than your “normal” idea of mixed precision.</li>
<li>We do <strong>not</strong> convert the model weights to BF16/FP16</li>
<li>Instead we <strong>wrap the forward pass</strong> with <code>autocast</code> to convert the gradients automatically</li>
<li>This preserves the original precision of the weights, which leads to stable training and better fine-tuning later on.</li>
<li><strong>If you use <code>.bf16()</code> weights, you are STUCK in bf16 perminantly</strong></li>
</ul>

<aside class="notes">
<p>What is actually happening: * Linear Layers and other certain compatible layers are wrapped in a special version that allows for FP8 computation * The general forward pass is wrapped around BF16 * This means that the most memory saved is done during the gradients of the model, <em>not</em> the model itself. * With tools like <code>MS-AMP</code> we can convert more chunks into lower precision, but again like before stable training occurs when the models weights are in full precision and the backprop happens in full precision too.</p>

<h2>Key Takeaways:</h2>
<ul>
<li>You can scale out training with <code>accelerate</code>, FSDP, and DeepSpeed across multiple GPUs to train bigger models</li>
<li>Techniques like <code>FP8</code> can help speed up training some and reduce computational overhead</li>
<li>Comes at a cost of end-precision and locking model weights for futher fine-tunes if not careful</li>
