TITLE:
FastSharedMemory: Ultra-Fast Zero-Copy IPC & Shared RAM Mappings for Java 🚀

DESCRIPTION:
Demonstrating FastSharedMemory, a native Win32 Named Shared Memory mapped file library for Java. Enables zero-copy Inter-Process Communication (IPC) across multiple Java JVMs and C++ processes with microsecond latency.

TECHNICAL HIGHLIGHTS:

  • Win32 Named Shared Memory: Direct CreateFileMapping and MapViewOfFile native bindings.
  • Zero-Copy Architecture: Share multi-megabyte buffers between separate OS processes without copy overhead.
  • Native Pointer Integration: Works directly with FastPointer address arithmetic.
  • Multi-Process Synchronization: Safe cross-process memory segment creation, opening, and closing.

RESULTS:

  • IPC Latency: Sub-microsecond zero-copy read/write operations
  • Throughput: Limited only by system RAM bandwidth
