## QEX: Quantum EXpressions lattice field theory framework

QEX is a high-level framework for lattice field operations

written in the language [Nim](https://nim-lang.org).

It provides optimized lattice field operations, including SIMD support,

for CPU architectures (native GPU support is currently experimental).

Since Nim compiles to native C/C++, directly calling any C/C++ lattice

code or library from QEX is relatively easy to do.

Some simple code examples are here

 [ex0.nim](src/examples/ex0.nim)

 [ex1.nim](src/examples/ex1.nim).

It currently supports

- U(1), SU(2..4) gauge fields in any dimension

- SciDAC I/O

- Gauge fixing

- Staggered solver and forces (Asqtad, HISQ, nHYP)

- Wilson solver (no clover yet)

- Interface for Chroma, Grid, QUDA interoperability
