iblep documentation

This site documents the executables used to compute connected, disconnected, and real radiative corrections in lattice QCD with the iblep software.

First Steps

Read these pages in order to familiarise yourself with the software:

1. Getting started covers the supported build/runtime environment and a first iblep-conn-lep run.
2. Regression tests explains how to run the suite of regression tests to ensure your build reproduces verified results.
3. Workflows provides a high-level overview of the workflows.

The dependency graph below shows the data flow between different workflows:
