Thus at the end of the 10 seconds, `buffered_pcm` can have some samples at the end that do not form a complete 1024 sample chunk. This fixes that by tracking when there is a partial chunk at the end of the buffer, and leaving it in `buffered_pcm` to be processed on the next loop iteration.

Direct copy. Verified block sizes. (#3097) * Add direct copy for floats in quantization * Calling q matmul directly gives slightly different results, but within ggml error leniency * fix quantized_mm test. Flip a and b input to matmul * Add compile time verification of block sizes being equal to vec dot type block sizes * Since we have verified that the block sizes are equal we can simplify qmatmul * clippy * Improved direct copy. Add comment to debug assert * Add more info to quantized matmul test failures * Disable quantized_mm for bf16 temporarily --- candle-core/src/quantized/k_quants.rs | 121 ++++++++++++++++++-------- candle-core/tests/quantized_tests.rs | 85 ++++++++++-------- 2 files changed, 138 insertions(+), 68 deletions(-) diff --git a/candle-core/src/quantized/k_quants.rs b/candle-core/src/quantized/k_quants.rs index ef31ceaaac..bca98b15bf 100644 --- a/candle-core/src/quantized/k_quants.rs +++ b/candle-core/src/quantized/k_quants.rs @@ -5,7 +5,7 @@ use super::utils::{ use super::GgmlDType; use crate::Result; use byteorder::{ByteOrder, LittleEndian}; -use half::{bf16, f16}; +use half::{bf16, f16, slice::HalfFloatSliceExt}; use rayon::prelude::*; // Default to QK_K 256 rather than 64. @@ -22,6 +22,7 @@ pub const QK8_1: usize = 32; pub trait GgmlType: Sized + Clone + Send + Sync { const DTYPE: GgmlDType; const BLCK_SIZE: usize; + const DIRECT_COPY: bool = false; type VecDotType: GgmlType; // This is only safe for types that include immediate values such as float/int/... @@ -31,6 +32,12 @@ pub trait GgmlType: Sized + Clone + Send + Sync { fn to_float(xs: &[Self], ys: &mut [f32]) -> Result<()>; fn from_float(xs: &[f32], ys: &mut [Self]) -> Result<()>; + fn direct_copy(_xs: &[f32], _ys: &mut [Self]) -> Result<()> { + Err(crate::Error::Msg( + "direct_copy not implemented for this type".into(), + )) + } + /// Dot product used as a building block for quantized mat-mul. /// n is the number of elements to be considered. fn vec_dot(n: usize, xs: &[Self], ys: &[Self::VecDotType]) -> Result; @@ -658,8 +665,24 @@ impl GgmlType for BlockQ8_1 { Self::vec_dot_unopt(n, xs, ys) } - fn vec_dot_unopt(_n: usize, _xs: &[Self], _ys: &[Self::VecDotType]) -> Result { - unimplemented!("no support for vec-dot on Q8_1") + fn vec_dot_unopt(n: usize, xs: &[Self], ys: &[Self::VecDotType]) -> Result { + let qk = QK8_1; + if !n.is_multiple_of(QK8_1) { + crate::bail!("vec_dot_q8_1_q8_1: {n} is not divisible by {qk}") + } + + // Generic implementation. + let mut sumf = 0f32; + for (xs, ys) in xs.iter().zip(ys.iter()) { + let sum_i = xs + .qs + .iter() + .zip(ys.qs.iter()) + .map(|(&x, &y)| x as i32 * y as i32) + .sum::(); + sumf += sum_i as f32 * f16::to_f32(xs.d) * f16::to_f32(ys.d) + } + Ok(sumf) } fn from_float(xs: &[f32], ys: &mut [Self]) -> Result<()> { @@ -1838,32 +1861,39 @@ impl GgmlType for BlockQ8K { } } -// https://github.com/ggerganov/llama.cpp/blob/b5ffb2849d23afe73647f68eec7b68187af09be6/ggml.c#L10605 +// https://github.com/ggml-org/llama.cpp/blob/aa3ee0eb0b80efca126cedf9bcb4fb5864b46ce3/ggml/src/ggml-cpu/ggml-cpu.c#L1205 pub fn matmul( - mkn: (usize, usize, usize), + (m, k, n): (usize, usize, usize), lhs: &[f32], rhs_t: &[T], dst: &mut [f32], ) -> Result<()> { - let (m, k, n) = mkn; + debug_assert_eq!( + T::BLCK_SIZE, + T::VecDotType::BLCK_SIZE, + "Mismatched block sizes" + ); + if m * k != lhs.len() { - crate::bail!("unexpected lhs length {} {mkn:?}", lhs.len()); + crate::bail!("unexpected lhs length {} ({m},{k},{n})", lhs.len()); } + let k_in_blocks = k.div_ceil(T::BLCK_SIZE); - let k_in_lhs_blocks = k.div_ceil(T::BLCK_SIZE); - let k_in_rhs_blocks = k.div_ceil(T::VecDotType::BLCK_SIZE); - // TODO: Do not make this copy if the DotType is f32. // TODO: Pre-allocate this. - let mut lhs_b = vec![T::VecDotType::zeros(); m * k_in_lhs_blocks]; - for row_idx in 0..m { - let lhs_b = &mut lhs_b[row_idx * k_in_lhs_blocks..(row_idx + 1) * k_in_lhs_blocks]; - let lhs = &lhs[row_idx * k..(row_idx + 1) * k]; - T::VecDotType::from_float(lhs, lhs_b)?

This is necessary for large models that are distributed across multiple files to avoid memory constraints during model storage and distribution. The new method accepts a slice of file paths instead of a single directory, allowing direct specification of shard files. It uses mmaped_safetensors for efficient memory usage when loading from multiple weight files. Key differences from build_unet: - Accepts &[P] where P: AsRef for multiple file paths - Uses from_mmaped_safetensors with file list instead of directory - Maintains same signature for in_channels, use_flash_attn, and dtype Use case: Loading models like FLUX or large SD3.5 variants that are distributed as model-00001-of-00003.safetensors, model-00002-of-00003.safetensors, etc. Example usage: "model-00001-of-00002.safetensors", "model-00002-of-00002.safetensors", ]; let unet = config.build_unet_sharded(&unet_files, &device, 4, false, DType::F32)?; * Update candle-transformers/src/models/stable_diffusion/mod.rs --------- Co-authored-by: ivarflakstad <69173633+ivarflakstad@users.noreply.github.com> --- .../src/models/stable_diffusion/mod.rs | 19 +++++++++++++++++++ 1 file changed, 19 insertions(+) diff --git a/candle-transformers/src/models/stable_diffusion/mod.rs b/candle-transformers/src/models/stable_diffusion/mod.rs index 4c685209cb..3c101fc69b 100644 --- a/candle-transformers/src/models/stable_diffusion/mod.rs +++ b/candle-transformers/src/models/stable_diffusion/mod.rs @@ -491,6 +491,25 @@ impl StableDiffusionConfig { Ok(unet) } + pub fn build_unet_sharded>( + &self, + unet_weight_files: &[P], + device: &Device, + in_channels: usize, + use_flash_attn: bool, + dtype: DType, + ) -> Result { + let vs_unet = + unsafe { nn::VarBuilder::from_mmaped_safetensors(unet_weight_files, dtype, device)? }; + unet_2d::UNet2DConditionModel::new( + vs_unet, + in_channels, + 4, + use_flash_attn, + self.unet.clone(), + ) + } + pub fn build_scheduler(&self, n_steps: usize) -> Result> { self.scheduler.build(n_steps) } From ad1da3430f506663ea6e862851e23f3d82b68ef6 Mon Sep 17 00:00:00 2001 From: ivarflakstad <69173633+ivarflakstad@users.noreply.github.com> Date: Wed, 8 Oct 2025 15:00:26 +0200 Subject: [PATCH 229/329] Fix metal get_function error (#3114) --- candle-metal-kernels/src/kernel.rs | 3 +-- candle-metal-kernels/src/metal/library.rs | 2 +- 2 files changed, 2 insertions(+), 3 deletions(-) diff --git a/candle-metal-kernels/src/kernel.rs b/candle-metal-kernels/src/kernel.rs index be531dc8fc..e111328857 100644 --- a/candle-metal-kernels/src/kernel.rs +++ b/candle-metal-kernels/src/kernel.rs @@ -134,8 +134,7 @@ impl Kernels { ) -> Result { let func = self .load_library(device, source)? - .get_function(name, constants) - .map_err(|e| MetalKernelError::LoadFunctionError(e.to_string()))?; + .get_function(name, constants)?; Ok(func) } diff --git a/candle-metal-kernels/src/metal/library.rs b/candle-metal-kernels/src/metal/library.rs index c6a4f2a176..07f9217cfd 100644 --- a/candle-metal-kernels/src/metal/library.rs +++ b/candle-metal-kernels/src/metal/library.rs @@ -32,7 +32,7 @@ impl Library { None => self .raw .newFunctionWithName(&NSString::from_str(name)) - .ok_or(MetalKernelError::LoadFunctionError("".to_string()))?, + .ok_or(MetalKernelError::LoadFunctionError(name.to_string()))?, }; Ok(Function { raw: function }) From 256c4e29786e75e3ab0a93130d9ccf90a11c3ab6 Mon Sep 17 00:00:00 2001 From: ivarflakstad <69173633+ivarflakstad@users.noreply.github.com> Date: Wed, 8 Oct 2025 15:01:15 +0200 Subject: [PATCH 230/329] Quantization use debug_assert in hot paths (#3109) * Add direct copy for floats in quantization * Calling q matmul directly gives slightly different results, but within ggml error leniency * fix quantized_mm test.
