llama.cpp 移除关键性能标志,开发者寻找新方法提升速度

一位开发者详细介绍了 llama.cpp 项目中一个至关重要的性能标志 `-sm row` 的丢失和最终的替换过程。最初,该标志通过在设备之间分割张量,显著提高了多 GPU 设置的吞吐量。然而,使用 Gemma 等新架构时出现了问题,导致行分割时崩溃,迫使切换到较慢的层分割。最终,`-sm row` 标志被完全从 llama.cpp 中移除,但通过并行处理和推测解码等正交功能,性能得到了恢复甚至超越。 AI

    <p>The single most important llama.cpp flag for my dual Tesla P40 setup was <code>-sm row</code>. It split every layer's tensors across both GPUs and it was worth nearly double the throughput of the alternative: 12-14 tokens/sec against about 7 for layer split. Every stack I buil…
