Class ZeroCopyOperations

Namespace

DotCompute.Memory

Assembly

DotCompute.Memory.dll

High-performance zero-copy operations using Span<T> and Memory<T>:

• Memory-mapped file operations for large datasets
• Pinned memory operations with automatic cleanup
• Vectorized memory operations with SIMD acceleration
• Unsafe pointer operations for maximum performance
• Interop-friendly memory layouts for native code
• Buffer slicing and views without allocation Target: Eliminate 95%+ of memory copies in hot paths
