- <h2> Chroma-Meas Docker Image for Lattice QCD</h2> <p>This Docker image provides a pre-compiled Chroma environment, specialized for computing baryon and meson two-point (2pt) correlation functions in lattice Quantum Chromodynamics (QCD). All measurements in this image run on CPU. It supports loading precomputed propagators to generate 2-point functions and on-the-fly propagator generation from gauge configurations.</p> <h3>Pull & Load the Docker Image</h3> <p>1. Pull from GHCR:</p> <p>docker pull ghcr.io/hubl1/chroma-meas:latest</p> <p>2. If GHCR is unavailable, load from Zenodo archive:</p> <p>curl -L -o chroma-meas-v1.0.0.tgz https://zenodo.org/record/15493501/files/chroma-meas-v1.0.0.tgz</p> <p>tar -xzf chroma-meas-v1.0.0.tgz</p> <p>docker load -i chroma-meas-v1.0.0.tgz</p> <h3>Input Data Layout</h3> <p>To download the complete dataset:</p> <p>curl -L -o lqcd_data.tgz https://zenodo.org/record/15455605/files/lqcd_data.tgz</p> <p>tar -xvzf lqcd_data.tgz</p> <p>After unpacking:</p> <p>lqcd_data/</p> <p>├── baryon_meson_data_h5 # raw 2pt correlators (~25 GB)</p> <p>├── precomputed_Propagators # precomputed propagators for quick 2pt</p> <p>├── Propagators # output directory (auto-created)</p> <p>├── Configuration # gauge configs for on-the-fly inversion</p> <p>├── precomputed_pydata_eff_mass # effective-mass fits (~3.1 GB)</p> <p>└── precomputed_pydata_global_fit # global fit data (~18 MB)</p> <h3>Run the Container</h3> <p>Mount your LQCD data directory and start an interactive shell:</p> <p>docker run –rm -it -v /your/local/path/lqcd_data:/lqcd_data ghcr.io/hubl1/chroma-meas:latest bash</p> <p>Inside the container, ensure /lqcd_data contains the required files, then:</p> <p>From inside the container shell:</p> <p>• Baryon & meson 2pt:</p> <p>mpirun –allow-run-as-root -n 4 chroma -i ./baryon_2pt.xml</p> <p>• Generate propagators (CPU):</p> <p>mpirun –allow-run-as-root -n 24 chroma -i ./cpu_inverter.xml</p> <h3>Supported Particles</h3> <p>Light Sector: PROTON, LAMBDA, SIGMA, XI, DELTA, SIGMA_STAR, XI_STAR, OMEGA, PION, ETA_S</p> <p>Charm Sector: LAMBDA_C, SIGMA_C, XI_C, XI_C_PRIME, XI_CC, OMEGA_C, OMEGA_CC, SIGMA_STAR_C, XI_STAR_C, OMEGA_STAR_C, XI_STAR_CC, OMEGA_STAR_CC, OMEGA_CCC, D, D_S, ETA_C, D_STAR, DS_STAR, JPSI, CHI_C0, CHI_C1, H_C</p> <p>All measurements use CPU. For vector mesons and spin-3/2 baryons, append _x, _y or _z for polarization (example: JPSI_x, OMEGA_STAR_CC_z).</p>
