Reserves a large amount of contiguous virtual memory space, and maps new allocations into it when the pool needs to grow. In this way, no memory is wasted. The pool is effectively a stack now, so all deallocations must be done in reverse order of the allocations.

An example of probably one of the worst cases before, partial offloading with increasing prompt sizes ./llama-bench -n 0 -p 8,16,32,64,128,256,512 -ngl 30 -m models/7B/ggml-model-Q4_0.gguf, the pool size dropped from 710 MB to 460 MB.

In my test implementation for peer access I was able to simply use CUDA_CHECK for the CUresult. I don't know whether that works universally though.

It didn't work for me, it is a different type and requires a different function to get the error description, cuGetErrorString.

The Makefile will probably need to be updated to add the possible paths for the CUDA driver library, the WSL path is a bit unconventional.

Tested on Ubuntu GTX 1660 and V100

The pool is effectively a stack now, so all deallocations must be done in reverse order of the allocations.

Should we RAII the allocations with a simple struct to guarantee this?

It could help in some cases, but many of the allocations are conditional, so we couldn't allocate the memory in the constructor, it would need to be done in a separate function, so it wouldn't guarantee that the order of the allocations is the same as the order of the declarations. It still is probably worth it just to remove the manual calls to pool_free, though.

More generally, I would like it if the correct order of allocations/deallocations was actually enforced. You could make it so that instead of just a size ggml_cuda_pool_malloc returns a struct that contains both a size and an index. A static variable in ggml_cuda_pool_malloc keeps track of the next index expected for deallocation. If it does not align an error is raised. (This PR should be fine even without such an enforcement mechanism though.)

This is already done, pool_free checks that the address being released is at the end of the pool.

Added the RAII struct and changed most of the code to use it, but this is a very error-prone process so another review would be good.

I think it was a mistake opting for a list of macros instead of hipify.

ggml_cuda_op_mul_mat is still directly using ggml_cuda_pool_malloc but I assume you're aware of that.

Using it in ggml_cuda_op_mul_mat is not so simple because just replacing the pointers and sizes with an array of cuda_pool_alloc wouldn't work, because the order of destruction wouldn't be the same as the order of allocations (reversed). It may work if the allocations are grouped per-device in a struct or tuple, but it requires more changes.

I'm assuming that the order in which the destructors is called is the reverse order in which the constructors were called so the correct order should be guaranteed.

Yes.

I think it is failing in a memcpy between devices with quantized models. Changing it to use cudaMemcpyPeerAsync fixes the issue. However the cudaMemcpyAsync still works when not using mmq:

                // copy src0, src1 to device if necessary
                if (src1->backend == GGML_BACKEND_GPU && src1_is_contiguous) {
                    if (id != g_main_device) {
                        if (convert_src1_to_q8_1) {
                            char * src1_ddq_i_source = src1_ddq[g_main_device] + src1_ddq_i_offset;
                            CUDA_CHECK(cudaMemcpyPeerAsync(src1_ddq_i, id, src1_ddq_i_source, g_main_device,
                                                            src1_ncols*src1_padded_col_size*q8_1_ts/q8_1_bs, stream));
                        } else {
                            float * src1_ddf_i_source = (float *) src1_extra->data_device[g_main_device];
                            src1_ddf_i_source += (i0*ne11 + src1_col_0) * ne10;
                            CUDA_CHECK(cudaMemcpyAsync(src1_ddf_i, src1_ddf_i_source, src1_ncols*ne10*sizeof(float),
                                                    cudaMemcpyDeviceToDevice, stream));
                        }
                    }

I think the difference is that the src1 source is only allocated on the pool when using mmq. So I think that the issue happens only when copying between pools of different devices. Does this sound right? Are there any other copies between different devices that should be changed? @JohannesGaessler

Fix: #4620

@city96 thanks for testing.

@city96 can you also test the version I just pushed to #4602 ? It may be the same issue that I found where (I think) peer access status changes during a data transfer.

Both llama 70B and mixtral currently fail with the following error:

CUDA error: cudaMemcpyAsync(src1_ddq_i, src1_ddq_i_source, src1_ncols*src1_padded_col_size*q8_1_ts/q8_1_bs, cudaMemcpyDeviceToDevice, stream): invalid argument

GGML_ASSERT: ggml-cuda.cu:240: !"CUDA error"

[cuda-fix-peer-sync commit e692c2d]

I have peer access disabled with LLAMA_CUDA_PEER_MAX_BATCH_SIZE=0 due to the 2 GPUs being connected to different CPUs (nvidia-smi topo -m reports SYS [Connection traversing PCIe as well as the SMP interconnect between NUMA nodes (e.g., QPI/UPI)]) - if that matters.

Happy to test anything else!

* flake.lock: update to hotfix CUDA::cuda_driver

Required to support #4606

* flake.nix: rewrite

1. 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. Update `flake.lock` with the latest goods.

* flake.nix: use finalPackage instead of passing it manually

* nix: unclutter darwin support

* nix: pass most darwin frameworks unconditionally

...for simplicity

* *.nix: nixfmt

nix shell github:piegamesde/nixfmt/rfc101-style --command \
    nixfmt flake.nix .devops/nix/*.nix

* flake.nix: add maintainers

* nix: move meta down to follow Nixpkgs style more closely

* nix: add missing meta attributes

nix: clarify the interpretation of meta.maintainers

nix: clarify the meaning of "broken" and "badPlatforms"

nix: passthru: expose the use* flags for inspection

E.g.:

```
❯ nix eval .#cuda.useCuda
true
```

* flake.nix: avoid re-evaluating nixpkgs too many times

* flake.nix: use flake-parts

* nix: migrate to pname+version

* flake.nix: overlay: expose both the namespace and the default attribute

* ci: add the (Nix) flakestry workflow

* nix: cmakeFlags: explicit OFF bools

* nix: cuda: reduce runtime closure

* nix: fewer rebuilds

* nix: respect config.cudaCapabilities

* nix: add the impure driver's location to the DT_RUNPATHs

* nix: clean sources more thoroughly

...this way outPaths change less frequently,
and so there are fewer rebuilds

* nix: explicit mpi support

* nix: explicit jetson support

* flake.nix: darwin: only expose the default

* flake.lock: update to hotfix CUDA::cuda_driver

Required to support ggerganov#4606

* flake.nix: rewrite

1. 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. Update `flake.lock` with the latest goods.

* flake.nix: use finalPackage instead of passing it manually

* nix: unclutter darwin support

* nix: pass most darwin frameworks unconditionally

...for simplicity

* *.nix: nixfmt

nix shell github:piegamesde/nixfmt/rfc101-style --command \
    nixfmt flake.nix .devops/nix/*.nix

* flake.nix: add maintainers

* nix: move meta down to follow Nixpkgs style more closely

cuda : ROCm AMD Unified Memory Architecture (UMA) handling (#4449)

* AMD ROCm: handle UMA memory VRAM expansions

This resolves #2797 by allowing ROCm AMD GPU users with a UMA to
dynamically expand the VRAM allocated to the GPU.

Without this, AMD ROCm users with shared CPU/GPU memory usually are
stuck with the BIOS-set (or fixed) framebuffer VRAM, making it
impossible to load more than 1-2 layers.

Note that the model is duplicated in RAM because it's loaded once for
the CPU and then copied into a second set of allocations that are
managed by the HIP UMA system. We can fix this later.

* clarify build process for ROCm on linux with cmake

* avoid using deprecated ROCm hipMallocHost

* keep simplifying the change required for UMA

* cmake: enable UMA-compatible allocation when LLAMA_HIP_UMA=ON

preventing any sampling. 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.

server : allow to generate multimodal embeddings (#4681)

server : fix OpenAI server sampling w.r.t. penalty. (#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.

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.

cmake : fix ld warning duplicate libraries libllama.a (#4671)

flake.nix : rewrite (#4605)

* flake.lock: update to hotfix CUDA::cuda_driver

Required to support https://github.com/ggerganov/llama.cpp/pull/4606

* flake.nix: rewrite

1. 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. Update `flake.lock` with the latest goods.

* flake.nix: use finalPackage instead of passing it manually

* nix: unclutter darwin support

* nix: pass most darwin frameworks unconditionally

...for simplicity

* *.nix: nixfmt

nix shell github:piegamesde/nixfmt/rfc101-style --command \
    nixfmt flake.nix .devops/nix/*.nix

* flake.nix: add maintainers

* nix: move meta down to follow Nixpkgs style more closely

* nix: add missing meta attributes

nix: clarify the interpretation of meta.maintainers

nix: clarify the meaning of "broken" and "badPlatforms"

nix: passthru: expose the use* flags for inspection

E.g.:

```
❯ nix eval .#cuda.useCuda
true
```

* flake.nix: avoid re-evaluating nixpkgs too many times

* flake.nix: use flake-parts

* nix: migrate to pname+version

* flake.nix: overlay: expose both the namespace and the default attribute

* ci: add the (Nix) flakestry workflow

* nix: cmakeFlags: explicit OFF bools

* nix: cuda: reduce runtime closure

* nix: fewer rebuilds

* nix: respect config.cudaCapabilities

* nix: add the impure driver's location to the DT_RUNPATHs

* nix: clean sources more thoroughly

...this way outPaths change less frequently,
and so there are fewer rebuilds

* nix: explicit mpi support

* nix: explicit jetson support

* flake.nix: darwin: only expose the default

* iq2_xxs: scalar and AVX2 dot products

Needed to change Q8_K to have quants in the -127...127 range,
else the IQ2_XXS AVX implementation becomes very awkward.
The alternative would have been to use Q8_0 instead. Perhaps
I'll change later, for now this is what we have.

* iq2_xxs: ARM_NEON dot product

Somehow strangely slow (112 ms/token).

* iq2_xxs: WIP Metal

Dequantize works, something is still wrong with the
dot product.

* iq2_xxs: Metal dot product now works

We have
PP-512 = 475 t/s
TG-128 = 47.3 t/s

Not the greatest performance, but not complete garbage either.

* iq2_xxs: slighty faster dot product

TG-128 is now 48.4 t/s

* iq2_xxs: slighty faster dot product

TG-128 is now 50.9 t/s

* iq2_xxs: even faster Metal dot product

TG-128 is now 54.1 t/s.

Strangely enough, putting the signs lookup table
into shared memory has a bigger impact than the
grid values being in shared memory.

* iq2_xxs: dequantize CUDA kernel - fix conflict with master

* iq2_xxs: quantized CUDA dot product (MMVQ)

We get TG-128 = 153.1 t/s

convert.py : fix vanilla LLaMA model conversion (#4818)

* Update Imports and Add Notes for Future Reference

- Updated import statements in `convert.py`.
- Added import for `AutoTokenizer` from `transformers` module.
- Added conditional import for `gguf` from the local directory.
- Added comments and notes for future reference.

Additional Notes:

- Noted removal of a redundant `TypeAlias` import.
- Noted the removal of a `gguf` debug statement.
- Commented on the presence of `ARCH` and `NDArray` definitions.
- Commented on cleaning up and refactoring data type definitions.

* Refine Model Hyperparameters and Params Class

- Updated type annotations to use `Optional` for clarity.
- Improved method names and attribute consistency.
- Removed unnecessary variables for better code readability.

Additional Notes:

- Highlighted the use of `Optional` for clearer intent.
- Ensured backward and forward compatibility.

* Restore BpeVocab and SentencePieceVocab classes

- Restored the BpeVocab class for handling BPE tokenization.
- Restored the SentencePieceVocab class for SentencePiece tokenization.

These classes are essential for maintaining the original behavior of the codebase.

* refactor: Standardize vocabulary handling with HfVocab

- Replaced VocabLoader with HfVocab, aligning vocabulary handling across classes.
- Updated initialization of HfVocab with local_files_only=True for AutoTokenizer.
- Introduced optional parameter fname_added_tokens for flexible added token management.
- Streamlined added token handling for clarity and conciseness.
- Maintained special tokens and IDs, enhancing token management.
- Simplified token processing methods for improved readability.
- Added a placeholder for score computation with a default value of -1000.0.
- Optimized newline token check for efficiency.
- Updated __repr__ function for clarity in representation.
- Adjusted type alias Vocab to include BpeVocab, SentencePieceVocab, and HfVocab.
- Removed redundant code related to special token handling, reverse vocabulary mapping, and vocabulary file detection.

This refactoring promotes a standardized and modular approach to vocabulary management, facilitating future integration with a VocabFactory and improving code maintainability and scalability.

* refactor: Enhance readability, functionality, and code quality

- Improved code formatting and readability for better maintainability.
- Refactored LazyUnpickler's CLASSES dictionary for clarity.
- Added print statements and warnings in check_vocab_size for user feedback.
- Removed find_vocab_file_path, as it's superseded by VocabFactory.
- Preparatory changes for upcoming classes: OutputFile and VocabFactory.
- Overall focus on code quality, error handling, and consistency.

These changes reflect a continuous effort to refine the codebase, ensuring it meets best practices and prepares for future enhancements, such as the VocabFactory.

* refactor: Update OutputFile class for enhanced model vocabulary management

- Restructured the constructor for improved readability.
- Updated `add_meta_arch` method for flexible model name determination.
- Introduced `handle_tokenizer_model` for mapping vocab types to supported tokenizer models.
- Streamlined vocabulary extraction with `extract_vocabulary_from_model`.
- Simplified vocabulary metadata addition using `add_meta_vocab`.
- Refactored `add_tensor_info` for clarity and consistency.
- Improved error handling for better user feedback.

These changes signify the development of a versatile and comprehensive `OutputFile` class, enabling efficient management of model conversion output, metadata, vocabulary, and tensor information.

* feat: Introduce VocabFactory for flexible vocabulary management in model conversion

- The VocabFactory class is added to facilitate modular vocabulary handling.
- The constructor initializes a directory path and detects vocabulary-related files.
- The _select_file method provides file paths based on vocabulary type (e.g., BPE, SentencePiece).
- _create_special_vocab generates special vocabularies, accommodating different types.
- The load_vocab method loads vocabularies, handling BPE, SentencePiece, and Hugging Face Fast Tokenizer.
- Error handling and logging enhance debugging and user feedback.
- The modular and flexible design simplifies vocabulary management and supports future extensions.

The VocabFactory class enhances code modularity and maintainability, allowing versatile vocabulary handling in the model conversion process.

* refactor: Improve code organization, argument parsing, and user interface

- Renamed 'default_outfile' to 'default_output_file' for clarity.
- Refactored argument parser setup into 'get_argument_parser' function.
- Introduced descriptive comments for each argument in the parser.
- Added '--vocab-type' argument with choices ["spm", "bpe", "hfft"] for vocabulary processing.
- Improved flag naming consistency: '--outfile' to '--out-file' and '--bigendian' to '--big-endian'.
- Enhanced error handling to prevent overwriting input data in 'default_output_file'.
- Made 'argv' in 'main' an optional parameter for flexibility.
- Introduced dynamic import for 'awq.apply_awq' based on 'args.awq_path' for conditional dependency.

These changes enhance code clarity, organization, and the user interface of the script, aligning it with Python best practices and improving maintainability.

* refactor: Further refine functionality, improve user interaction, and streamline vocabulary handling

- Renamed command-line arguments for clarity and consistency.
- Improved path resolution and import adjustments for robustness.
- Thoughtfully handled 'awq-path' and conditional logic for the weighted model.
- Enhanced model and vocabulary loading with the 'VocabFactory' class for structured and adaptable loading.
- Strengthened error handling and user feedback for a more user-friendly experience.
- Structured output file handling with clear conditions and defaults.
- Streamlined and organized the 'main' function for better logic flow.
- Passed 'sys.argv[1:]' to 'main' for adaptability and testability.

These changes solidify the script's functionality, making it more robust, user-friendly, and adaptable. The use of the 'VocabFactory' class is a notable enhancement in efficient vocabulary handling, reflecting a thoughtful and iterative approach to script development.

- Moved the special case check for `params.n_vocab == -1` to the top for immediate assertion.
- Flattened the conditional logic for improved clarity and predictability of the function's behavior.

These changes enhance the readability and functional correctness of the `check_vocab_size` function without altering its intended functionality.

* py : fix outfile and outtype

* py : suggest hint for missing vocab size

Python script to compare commits with llama-bench (#4844)

clip : support more quantization types (#4846)

Uses ggml functions instead of hardcoded names and adds support to quantize into the modern Q-K variants.
This is just the bare minimum to get k-types working - a more refined choice of types would be needed to get best quality on low quantizations.

I ran a few tests, it doesn't break anything I could notice and a Q6_K ViT works almost as well as Q8_0 but 3 times the inference speed.

llama : recognize 1B phi models (#4847)

This update categorizes models with 24 layers as MODEL_1B, ensuring compatibility with different Phi model variants without impacting existing Phi-2 model functionality.

llama : add additional suffixes for model params (#4834)

* llm_load_print_meta: Add additional suffixs for model params

server : add a `/health` endpoint (#4860)

* added /health endpoint to the server

* added comments on the additional /health endpoint

running on the CPU.

* iq2_xs: AVX2 dot product - 19.5 t/s

* iq2_xs: faster AVX2 dit product

21.4 t/s for TG-128, 59.2 t/s for PP-512.
The latter is 2x compared to the previous version.

llama : minimize size used for state save/load (#4820)

* examples : save-load-state: save only required state

* llama : only reserve n_vocab * n_batch at most for logits

llama_decode asserts that only n_batch tokens are passed each call, and
n_ctx is expected to be bigger than n_batch.

* llama : always reserve n_vocab * n_batch for logits

llama_context de-serialization breaks if the contexts have differing
capacity for logits and llama_decode will at maximum resize to
n_vocab * n_batch.

* llama : only save and restore used logits

for batch sizes of 512 this reduces save state in the best case by
around 62 MB, which can be a lot if planning to save on each message
to allow regenerating messages.

* llama : use ostringstream and istringstream for save and load

* llama : serialize rng into minimum amount of space required

* llama : break session version due to serialization changes

Fix ffn_down quantization mix for MoE models (#4927)

* Fix ffn_down quantization mix for MoE models

In #4872 I did not consider the part where every third
tensor is quantized with more bits. Fir MoE this leads to tensors
of the same layer being quantized with different number of bits,
which is not considered as a possibility in the inference implementation
(it is assumed all experts use the same quantization).

ggml : introduce GGML_CALL function annotation (#4850)

This change makes it possible to build ggml-cuda.cu and ggml-metal.m as
independent dynamic shared objects, that may be conditionally linked at
runtime in a multiplatform binary. It introduces a GGML_CALL annotation
that documents which functions have a cyclic call relationship, between
the application code and GPU modules.

This change does nothing, unless the build defines -DGGML_MULTIPLATFORM
which causes back-references and function pointers to conform to MS ABI
which is supported by NVCC, ROCm, XCode, GCC and Clang across platforms
