OktoBLAS

🏆 The First Independent BLAS to Beat PyTorch in ALL Sizes 🏆

🏆 Performance Results

All benchmarks on NVIDIA RTX 4070 Laptop GPU with GPU warmed up.

🚀 OktoTensor Training Performance (v1.0.9+)

Key Benefit: OktoTensor eliminates NumPy ↔ CUDA conversion overhead by keeping tensors GPU-resident.

FP16 GEMM

Fused Attention

📦 Installation

pip install oktoblas

📖 Quick Start

import oktoblas as ob
import numpy as np

# Check OktoBLAS info
ob.info()

# FP16 Matrix Multiplication (40+ TFLOPS!)
A = np.random.randn(2048, 2048).astype(np.float16)
B = np.random.randn(2048, 2048).astype(np.float16)
C = ob.matmul_fp16(A, B)

# Fused Attention (3.8x faster!)
Q = np.random.randn(4, 256, 64).astype(np.float32)
K = np.random.randn(4, 256, 64).astype(np.float32)
V = np.random.randn(4, 256, 64).astype(np.float32)
output = ob.attention(Q, K, V)

# 🚀 OktoTensor (v1.0.9+) - GPU-resident tensors (12.5x faster!)
x = ob.OktoTensor(np.random.randn(512, 128), device="cuda")  # Upload once, stays on GPU
w = ob.OktoTensor(np.random.randn(128, 256), device="cuda")  # Upload once, stays on GPU
result = x.matmul(w)  # Zero conversion overhead!
result_numpy = result.cpu()  # Explicit conversion when needed
