Effort.jl

Effort is a Julia package for fast computation of power spectrum multipoles in the Effective Field Theory of Large Scale Structure (EFTofLSS) framework. Using neural network emulators, it achieves performance of ~0.3 milliseconds per evaluation, compared to several seconds for traditional Boltzmann solver-based approaches.

The example page shows how to use Effort, while showing its computational performance.
