For the Impatient

You need git and Python 3.8+:

git clone https://github.com/LLNL/benchpark.git
cd benchpark
. setup-env.sh
benchpark --version

python3 -m venv my-env
. my-env/bin/activate

pip install -r requirements.txt

Set up a Workspace

benchpark system init --dest=</output/path/to/system_def_dir/mySystemName> <SystemName> compiler=<Compiler>
benchpark experiment init <mySystemName> <Benchmark> +/~<Boolean Variant> <String Variant>=<value>
benchpark setup <mySystemName>/<Benchmark> </output/path/to/workspace>

where:

• <Benchmark>: amg2023 | saxpy | etc. (predefined choices in Benchmarks and Experiments)

• <SystemName>: Cts | Tioga | etc. (predefined systems in System Specifications)

benchpark setup will output instructions to follow:

. <experiments_root>/setup.sh

Build an Experiment

cd <experiments_root>/<System>/<Benchmark>/workspace
ramble --workspace-dir . workspace setup

Run the Experiment

To run all of the experiments in the workspace:

ramble --workspace-dir . on

To run a single experiment in the workspace, invoke the execute_experiment script for the specific experiment (e.g., $workspace/experiments/amg2023/problem1/amg2023_cuda11.8.0_problem1_1_8_2_2_2_10_10_10/execute_experiment).

Experiment pass/fail

Once the experiments completed running, the command:

ramble --workspace-dir . workspace analyze

can be used to analyze figures of merit and evaluate success/failure of the experiments. Ramble generates a file with summary of the results in $workspace.

If the benchmark you are running is instrumented with Caliper, you can use the Caliper modifier (see Benchpark Modifiers) to collect detailed measurements you can later analyze with Thicket.
