About:
ParallelHashmap is a family of header-only C++ containers offering high-performance hashmap and btree implementations. It provides a drop-in replacement for std::unordered_map that delivers superior speed and memory efficiency through advanced open-addressing algorithms. The library is dependency-free and focuses on cache-friendly data layouts for optimal execution.
Key Features:
  • Header-only library, no compilation required
  • Drop-in replacement for STL containers
  • Superior performance and memory efficiency
  • Cache-friendly open-addressing design
  • Thread-safe options available
Use Cases:
  • High-performance computing and numerical simulations
  • Game development and real-time systems
  • Large-scale in-memory data processing
  • Performance-critical C++ applications
Alternatives:
  • Google Abseil – Provides similar high-performance containers but is a larger library
  • Boost.Container – Part of the Boost ecosystem, offers stable node containers
  • std::unordered_map – Standard library option, generally slower and uses more memory
