On my machine with 3x P40 LLaMA 2 70b q6_K crashes: LLaMA 2 7b q4_0 and LLaMA 2 13b q6_K work correctly. |
|
I did some performance testing on my Linux system with 3x P40:
The P40s are connected to the motherboard via PCIe 3.0 x16/x8/x8. Choosing the x16 GPU as the main GPU lets you use the full PCIe bandwidth. Choosing any of the other GPUs effectively reduces the interconnect speed to x8/x4/x4. For dual GPU use the interconnect speed is effectively limited to x8/x8. I was not able to test LLaMA 2 70b or Mixtral because they currently do not work with this PR. On my system the new scheme for distributing weights is slower. One of the reasons is probably that P40s are comparatively slow so the interconnect speed doesn't bottleneck them as much as e.g. 3x RTX 4090. Synchronization overhead may also depend on OS. Finally, because the P40s use MMQ they benefit from the performance optimizations in this PR: #3110 . For FP16 cuBLAS similar optimizations could be done by converting the hidden state to FP16 on the main device and caching the dequantized weight matrix (otherwise it is dequantized multiple times if tiling is enabled). |

Thanks for testing. There is an issue in the graph splitting logic that is causing some operations of each layer to be run on a different GPU, and that's why it fails with 70B, it creates too many splits. |

The graph split generation should be much better now. With 3080+3090Ti I get 3600 t/s pp 512, and 105 t/s tg 128. Compared to a single GPU, I get 4020 t/s pp, 121 t/s tg with only the 3090Ti, and 3320 t/s pp, 110 t/s tg with only the 3080. |

Token generation is I/O bound. So FP16 is going to be comparatively slow (which reduces the interconnect bottleneck). At the same time the hidden state is very small and thus can be transferred quickly between devices. So I think that this is just a scenario where the implementation on master has favorable conditions. |
I think there are some cases where the row splitting implementation can achieve higher tg performance than with a single GPU, so maybe this is one of them, but I am just guessing. I am already aware of some inefficiencies in the current implementation, for instance the way the data is copied between GPUs is very inefficient, but there is still a lot of work to do before this can be merged, so I think it is better to leave that for another PR. |

I have no idea what needs to be done to fix the swift build, the errors don't make sense to me. |

The swift builds are failing because #4691 makes the swift examples pull the The builds will be resolved after upstreaming the changes from this PR to the |

Nice job, glad to see! (And thanks, as this will close #4055 which I held dear :) For parallelism in prompt processing there is possibly another optimization (https://www.deepspeed.ai/tutorials/pipeline/) |

Does that work for inference? The article seems to be about training, by interleaving forward and backward passes, but I don't see how to apply that during inference. |

I'll still have to wrap my head around it and it's 7:00 AM. maybe I'm mistaken but if we process a batch of tokens through GPU1 (layers 1-10), then pass those to GPU2 (11-20), wouldn't we be able to process the next on GPU1 while GPU2 is still working ? |
What you can do is split a batch of e.g. 512 tokens into 4 batches of 128 tokens. If you then have 4 GPUs you can have the GPU with the first few layers work on the first batch first. Once the first batch has passed through the layers of the first GPU, the first GPU can start working on the second batch while the second GPU can start working on the first batch. In this particular example you could get up to 57% GPU utilization, so more than 2x more than without pipelining. For very large batches you could get up to ~100% GPU utilization. The problem with this approach is that the code in its current form very much does not like small batches in terms of performance:
So even if you do pipelining and get higher GPU utilization the overall performance could be worse. I have a prototype for int8 matrix matrix multiplication using tensor cores; I'll make a related PR later today (did not yet investigate performance in detail but could be better for small batches). |

This PR changes perplexity in non-negligible ways. I came across this while looking into #4900. I checked out the version just before #4872 was merged (49662cb), quantized Mixtral-instruct-8x7B with This is just one anecdotal example, but |
|
I'm looking into this and a difference in the PPL values with partial offloading is expected from this PR, but I cannot say yet if the large delta that you observe is within that expectation. The reason that the results change after this PR is that for the non-offloaded layers, the RoPE is now computed on the CPU, while before this PR, it was computed on the GPU - i.e. the Lines 6174 to 6178 in 584d674 The same analysis is also valid for the softmax in the attention, because the Bottomline is that for non-offloaded layers, RoPE and softmax are now running on the CPU, while before they ran on the GPU, so some change in PPL should be observed. I did the following experiment - I checked out the commit before this PR and applied this patch: diff --git a/llama.cpp b/llama.cpp

I'll keep looking as I am not yet 100% sure that there isn't some other issue Edit: for Mixtral with These were on the CPU before, so I suspect this should explain the difference in the PPL values.

@ggerganov Thanks for the detailed explanation of differences introduced by this PR. Somehow I find it unlikely that running RoPE and softmax on the CPU instead of the GPU can cause such large differences in PPL. My latest example is Mixtral-8x7B quantized with |

All this work and afterwards 2x3090 went from 18.9 t/s to 15 t/s and 2xP40 went from 8.8 to like 8.5, regardless of which layer split option is used. |
|
Are you on Windows? I also noticed a single GPU performance regression for my AMD GPU but we were not able to pin down what the cause is. Possibly some API call that is fast on Linux with CUDA is slow for Windows and HIP. |
|
I am on linux. I was worried about this so I am building an older version to double check my speeds. Around dec 27th, which is when my backup is from, I was still getting at least 16.3 t/s so there have been regressions along the way. I probably wasn't paying attention because I was using mixtral. |
There are performance regression on rdna2 on single GPU,but I haven't notice that on a rdna3 GPU like 7900xtx on Windows at least. |
|
Just to add my experience: using 2x RTX A6000 with an Nvlink bridge I'm only getting around 60% of the tokens/s using the new default layer splitting vs row splitting. I'm guessing without the Nvlink it would be about the same. |
Can you do a git bisect to check which commit is to blame? |
|
I have to investigate. I have snapshots from nov 29, dec 27 and fresh. Going back to earlier ones isn't helping at the moment, I also haven't rebooted in about 3 months. |
|
Something weird is going on because I no longer hit 18.x back to november backup. Then again.. my outdoor temperatures are around 30f and my CPUs top out at 14c with the fans pushed to low. You'd think it works better colder but I guess not. I still have my old benchmarks saved on the same models so it's not in my head. By the current measurement I went from 14.4 to 15.4t/s. I suppose it will remain a mystery for a while longer. |

Note this only applies to OpenAI API compatible HTTP server requests. The solution is to use the default values that OpenAI documents, as well as ensuring we use the llama.cpp defaults for the rest. I've tested this change still ensures deterministic output by default. If a "temperature" greater than 0 is explicitly passed, then output is unique each time. If "seed" is specified in addition to "temperature" then the output becomes deterministic once more.

(#4675) server : replace sleep with condition variables (#4673) The server currently schedules tasks using a sleep(5ms) busy loop. This adds unnecessary latency since most sleep implementations do a round up to the system scheduling quantum (usually 10ms). Other libc sleep impls spin for smaller time intervals which results in the server's busy loop consuming all available cpu. Having the explicit notify() / wait() code also helps aid in the readability of the server code. See mozilla-Ocho/llamafile@711344b llava-cli : refactor to use sampling library (#4669) This change makes it possible to use flags like `--grammar` when using the `llava-cli` program. The rest is just code cleanup deleting a long standing TODO comment. This change also ensures that logging information is emitted to stderr which helps the `llava-cli` command be more friendly to shell scripts.

Split into separate files per output. 2. Added overlays, so that this flake can be integrated into others. The names in the overlay are `llama-cpp`, `llama-cpp-opencl`, `llama-cpp-cuda`, and `llama-cpp-rocm` so that they fit into the broader set of Nix packages from [nixpkgs](https://github.com/nixos/nixpkgs). 3. Use [callPackage](https://summer.nixos.org/blog/callpackage-a-tool-for-the-lazy/) rather than `with pkgs;` so that there's dependency injection rather than dependency lookup. 4. Add a description and meta information for each package. The description includes a bit about what's trying to accelerate each one. 5. Use specific CUDA packages instead of cudatoolkit on the advice of SomeoneSerge. 6. Format with `serokell/nixfmt` for a consistent style. 7.

This PR completes the integration of llama.cpp with ggml-backend. The main change is that partial offloading is handled through
ggml_backend_sched, and it is supported with all the backends. This also implements multi-GPU support by offloading different layers to different GPUs, instead of splitting matrices by rows. While this does not achieve the same level of parallelism as row-level splitting, it requires less synchronization and it may be more efficient in some cases.There is still some work to do, but layer-level multi-GPU with CUDA should already work. For me with WSL, this is significantly faster than the current row-level splitting, so I am opening this now in case anyone wants to give it a try.
-tscan be used as usual to configure the fraction of layers to offload to each GPU.TODO
