Chroma

The Chroma package supports data-parallel programming constructs for lattice field theory and in particular lattice QCD. It uses the SciDAC QDP++ data-parallel programming (in C++) that presents a single high-level code image to the user, but can generate highly optimized code for many architectural systems including single node workstations, multi and many-core nodes, clusters of nodes via QMP, and classic vector computers.

Single-Node Server Requirements

Note: The Chroma application container assumes that the server contains the required x86-64 CPU(s) and at least one of the listed AMD GPUs. Also, the server must have one of the required operating systems and the listed ROCm driver version installed to run the Docker container. The server must also have a Docker Engine installed to run the container. Please visit the Docker Engine install web site at https://docs.docker.com/engine/install/ to install the latest Docker Engine for the operating system installed on the server. If Singularity use is planned, please visit https://sylabs.io/docs/ for the latest Singularity install documentation.

Please visit https://rocmdocs.amd.com/en/latest/Installation_Guide/Installation-Guide.html for ROCm installation procedures and validation checks.

Running Containers

Launch the container using the following command, substituting the image name from the Pull Command section above if newer:

docker run --rm -it --device /dev/dri --device /dev/kfd --security-opt seccomp=unconfined amdih/chroma:3.43.0 /bin/bash

The container contains an example benchmark problem, which can be executed as follows

cd /benchmark
run-benchmark --ngpus 1

The benchmark will be executed and run on a single GPU. The console will display the progress of the solver.

You can run the benchmarks on 2, 4, and 8 GPUs by modifying the value of the --ngpus parameter.

Run Using Singularity

This section assumes that an up-to-date version of Singularity is installed on your system and properly configured for your system. Please consult with your system administrator or view official Singularity documentation.

Pull and convert docker image to singularity image format, substituting the image name from the Pull Command section above if newer:

singularity pull chroma_3.43.0.sif docker://amdih/chroma:3.43.0

Running Application

You can then use examples from the preceding section to use the image. For example, to run the benchmark problem, you may do

singularity run --pwd /benchmark --writable-tmpfs chroma.sif run-benchmark --ngpus 1

Similar to Docker, you can run the benchmarks on 2, 4, and 8 GPUs by modifying the value of the --ngpus parameter.
