Some of the existing code deployed for data or compute intensive applications is missing the necessary optimisations needed to efficiently exploit modern CPU processors. While multi-threading comes as the first easy step towards optimized code, some more advanced techniques require expert knowledge for maximum performance and data throughput (vectorisation, cache optimisation)

Xcelerit helps clients modernise their existing CPU code resulting in large performance gains without any hardware change.

Whitepaper: A Guide to CPU Code Modernisation

Today’s CPUs are complex, with features such as multi-core, hyperthreading, turbo mode, vectorisation, or several layers of cache. However, using these features effectively in software to achieve the highest possible performance is hard. This white paper discusses recent CPUs and gives guidelines how to use their features to the best advantage in software code.

  • Achieving linear scaling with cores
  • CPU caching structure and optimisation
  • Vectorisation: Automatic and manual
  • Memory organisation and access patterns
  • Hyperthreading and Turbo mode
