🔧 Installation

# From PyPI (coming soon)
pip install oktoblas

# From source (requires Rust + CUDA)
pip install maturin
maturin develop --release

📖 Quick Start

import oktoblas as ob
import numpy as np

# FP16 Matrix multiplication - FASTER than PyTorch!
A = np.random.randn(2048, 2048).astype(np.float16)
B = np.random.randn(2048, 2048).astype(np.float16)
C = ob.matmul_fp16(A, B)  # 35+ TFLOPS! Beats PyTorch!

# FP32 Matrix multiplication
A32 = np.random.randn(4096, 4096).astype(np.float32)
B32 = np.random.randn(4096, 4096).astype(np.float32)
C32 = ob.matmul(A32, B32)  # 9+ TFLOPS

# Fused Attention - 3x FASTER than PyTorch!
batch, seq_len, head_dim = 4, 512, 64
Q = np.random.randn(batch, seq_len, head_dim).astype(np.float32)
K = np.random.randn(batch, seq_len, head_dim).astype(np.float32)
V = np.random.randn(batch, seq_len, head_dim).astype(np.float32)
output = ob.attention(Q, K, V)  # 346% PyTorch!

# Check configuration
ob.info()

# Run benchmark
results = ob.benchmark("gemm_fp16", size=2048, iterations=100)
print(f"OktoBLAS: {results['oktoblas_tflops']:.1f} TF")
print(f"PyTorch:  {results['pytorch_tflops']:.1f} TF")
print(f"Ratio:    {results['ratio']:.1f}%")

🔥 PyTorch Integration

import torch
import oktoblas as ob

# Use OktoBLAS with PyTorch tensors
A = torch.randn(2048, 2048, device='cuda', dtype=torch.float16)
B = torch.randn(2048, 2048, device='cuda', dtype=torch.float16)

# FASTER than torch.matmul!
C = ob.torch_matmul_fp16(A.cpu().numpy(), B.cpu().numpy())

# With autograd support (coming soon)
# loss = C.sum()
# loss.backward()
