Contribution: pdf


We present a new lattice field theory software framework
designed with ease of use, flexibility, efficiency and portability
in mind. The framework is written using the Nim programming
language which offers many of the features one would find in a
high-level scripting language, while in fact being a strongly-typed
language with full control over low-level optimizations. This
allows us to present a simple expression-based language to the end
user that can be transformed into highly optimized code for a
particular architecture. We will discuss the features of the QEX
framework, performance results and development plans.
