为方便说明,我们假设模型输入为(32, 768),这里的 32 表示batch_size,模型输出为(32, 768),使用 4 个GPU训练。nn.DataParallel起到的作用是将这 32 个样本拆成 4 份,发送给 4 个GPU 分别做 forward,然后生成 4 个大小为(8, 768)的输出,然后再将这 4 个输出都收集到cuda:0上并合并成(32, 768)。

限制inflight copy op的数量,让cuda caching allocator能尽量复用已经分配的block,避免过高的显存占用(内存复用 vs 足够的并行度,in general)。 通过torch_dispatch 来结合 recomputation 和 offloading (to CPU / in GPU) 到一起,避免一些昂贵的op(attention/matmul)的重计算,换句话说,就是在backward时重计算廉价...

This is NOT what Dear ImGui does. Dear ImGui outputs vertex buffers and a small list of draw calls batches. It never touches your GPU directly. The draw call batches are decently optimal and you can render them later, in your app or even remotely....
