# fp4-gemm
|
| 2 |
|
| 3 |
+
FlashRT native Blackwell NVFP4 A4W4 GEMM kernels.
|
|
|
|
| 4 |
|
| 5 |
+
This package consumes packed FP4 E2M1 tensors plus CUTLASS Sm1xx SFA/SFB scale
|
| 6 |
+
buffers and produces BF16 output. It is designed to pair with
|
| 7 |
+
`flashrt/fp4-fused-ops` and other static low-bit transformer/diffuser runtime
|
| 8 |
+
paths.
|

|

|

## Tensor Contract
|
| 27 |
+
|
| 28 |
+
- `a_packed`: `torch.uint8`, shape `(M, K / 2)`.
|
| 29 |
+
- `b_packed`: `torch.uint8`, shape `(N, K / 2)`.
|
| 30 |
+
- `sfa`: `torch.uint8`, CUTLASS SFA layout for `(M, K)`.
|
| 31 |
+
- `sfb`: `torch.uint8`, CUTLASS SFB layout for `(N, K)`.
|
| 32 |
+
- output: `torch.bfloat16`, shape `(M, N)`.
|
| 33 |
+
- `K` must be divisible by 16.
|
| 34 |
+
- Targets: Blackwell `sm_110a` (Jetson AGX Thor, CUDA 13+) and `sm_120a`
|
| 35 |
+
(RTX Blackwell, CUDA 12.8+).
|
| 36 |
+
|
| 37 |
+
`variant` selects the CUTLASS schedule:
|
| 38 |
+
|
| 39 |
+
- `-1`: architecture-aware auto-dispatch (public default).
|
| 40 |
+
- `0`: default `<128,128,256>` cooperative schedule.
|
| 41 |
+
- `1`: widen `<128,256,128>` schedule, intended for very large `N`.
|
| 42 |
+
- `2`: pingpong schedule for A/B testing shape-specific wins.
|
| 43 |
+
|
| 44 |
+
The canonical linear API and FP4/SFA quantize/dequantize helpers are available
|
| 45 |
+
on both SM110 and SM120. SM110 additionally provides the GROOT N1.7 production
|
| 46 |
+
epilogues `nvfp4_gemm_bias_bf16`, `nvfp4_gemm_bias_residual_bf16`, and
|
| 47 |
+
`nvfp4_gemm_bias_gelu_nvfp4`. The latter emits packed FP4 plus CUTLASS SFA so
|
| 48 |
+
the following projection can consume it without a BF16 materialization and a
|
| 49 |
+
standalone quantization launch. Stream-K and the older BF16 GELU epilogue keep
|
| 50 |
+
their existing SM120 dispatch and reject unsupported architectures explicitly.
|
| 51 |
+
|
| 52 |
+
The SM110 release gate includes the production `(M,N,K)` shapes
|
| 53 |
+
`(41,4608,1536)`, `(41,6144,1536)`, and `(41,1536,6144)`, plus the legacy
|
| 54 |
+
`M=51` compatibility row. The kernels are the native sources used by FlashRT's
|
| 55 |
+
GROOT N1.7 Thor NVFP4 pipeline.
|
| 56 |
+
|
| 57 |
+
## Minimal Usage
|
| 58 |
+
|
| 59 |
+
```python
|
| 60 |
+
from kernels import get_kernel
|
| 61 |
+
import torch
|
| 62 |
+
|
| 63 |
+
ops = get_kernel("flashrt/fp4-gemm", version=1, trust_remote_code=True)
|
| 64 |
+
|
| 65 |
+
x = torch.randn((32, 256), device="cuda", dtype=torch.float16)
|
| 66 |
+
w = torch.randn((512, 256), device="cuda", dtype=torch.float16)
|
| 67 |
+
|
| 68 |
+
a_packed, sfa = ops.quantize_fp4_sfa_fp16(x, is_sfb=False)
|
| 69 |
+
b_packed, sfb = ops.quantize_fp4_sfa_fp16(w, is_sfb=True)
|
| 70 |
+
|
| 71 |
+
y = ops.nvfp4_gemm_bf16(a_packed, b_packed, sfa, sfb, alpha=1.0)
|
| 72 |
+
```
|
| 73 |
+
|
| 74 |
+
For BF16 model activations, use the direct producer so the hot path does not
|
| 75 |
+
materialize an intermediate FP16 tensor:
|
| 76 |
+
|
| 77 |
+
```python
|
| 78 |
+
x_bf16 = torch.randn((1, 5120), device="cuda", dtype=torch.bfloat16)
|
| 79 |
+
a_packed, sfa = ops.quantize_fp4_sfa_bf16(x_bf16)
|
| 80 |
+
```
|
| 81 |
+
|
| 82 |
+
The BF16 entry writes the same E2M1 bytes and CUTLASS SFA/SFB layout as
|
| 83 |
+
`quantize_fp4_sfa_fp16(x_bf16.to(torch.float16))` for finite FP16-range
|
| 84 |
+
inputs. It is an additive API; the existing FP16 producer remains unchanged.
|
| 85 |
+
|
| 86 |
+
The quantize/dequantize helpers are included for examples and validation. A
|
| 87 |
+
production runtime should keep weights prepacked and should avoid quantizing in
|
| 88 |
+
the hot path unless that producer kernel is part of the intended low-bit block.
|
| 89 |
+
|
| 90 |
+
Use the bias/GELU and residual variants to avoid returning to BF16
|
| 91 |
+
elementwise code between low-bit GEMMs. Stream-K variants are selected only
|
| 92 |
+
for the validated large down-projection shapes; unsupported shapes reject
|
| 93 |
+
rather than silently selecting a losing schedule.
|
| 94 |
+
|
| 95 |
+
## Validation
|
| 96 |
+
|
| 97 |
+
```bash
|
| 98 |
+
python fp4-gemm/tests/test_fp4_gemm.py --backend source --mode full

|
| 107 |
+
--artifact fp4-gemm/build/torch211-cxx11-cu130-aarch64-linux
|
| 108 |
+
```
|
| 109 |
+
|
| 110 |
+
The correctness reference dequantizes the same FP4/SFA and FP4/SFB inputs used
|
| 111 |
+
by the kernel, then computes the PyTorch GEMM reference from those dequantized
|
| 112 |
+
low-bit values.
|
| 113 |
+
|
| 114 |
+
The producer gate also checks the BF16 direct entry byte-for-byte against the
|
| 115 |
+
established FP16 compatibility chain at decode widths 5120, 6144 and 17408,
|
| 116 |
+
plus multi-row activation and SFB layouts.
