hptt

High-Performance Tensor Transpose library

HPTT is a high-performance C++ library for out-of-place tensor transpositions. Key Features: * Multi-threading support * Explicit vectorization * Auto-tuning (akin to FFTW) * Loop order * Parallelization * Multi architecture support * Explicitly vectorized kernels for (AVX and ARM) * Supports float, double, complex and double complex data types * Supports both column-major and row-major data layouts
