Termination Competition 2025 technical details

Execution Environment

Starting from 2025, TermComp runs on the RWTH HPC cluster.

Tools must be submitted as Docker images. The competition will run using Apptainer (which can run Docker images). During the competition, the following two commands will be executed in your container:

• solver --name
• solver --timeout=$timeout --category=$category $benchmark

So an executable named "solver" must be available in your container. The former command must print the name of your solver to stdout. The latter must analyze the provided $benchmark w.r.t.\ the rules of the given $category, taking the given $timeout into account.

A list with the exact category names will be published before the competition. They will essentially be identical to the names of the corresponding TPDB directories.

Resource limits:

• 4 cores
• 60s wallclock time
• 20.345 MiB RAM

Testing Locally

• Install Apptainer.
• Build and tag your docker image locally. In my case, its full name is loat/loat-termcomp:445e86.
• Convert your docker image to an Apptainer image via

apptainer build $apptainer_image.sif docker-daemon://$docker_image
So in my case, the full command is
apptainer build loat.sif docker-daemon:loat/loat-termcomp:445e86

• First test

apptainer exec $apptainer_image.sif solver --name
In my case, I get:
apptainer exec loat.sif solver --name

LoAT

• Then test

apptainer exec --writable-tmpfs -C --bind $TPDB:$TPDB $image solver --timeout=$timeout --category=$category $TPDB/$benchmark where $TPDB is the path to your clone of the TPDB.
In my case, I get:
apptainer exec --writable-tmpfs -C --bind $WORK/benchmarks/TPDB:$WORK/benchmarks/TPDB loat.sif solver --timeout=60 --category=Integer_Transition_Systems $WORK/benchmarks/TPDB/Integer_Transition_Systems/From_AProVE_2014/Velroyen08-alternDiv.jar-obl-8.smt2

NO

Lessons Learned from Testing

General

• The image must be for an amd64-architecture.

Docker - Apptainer incompatibilities

The following things must be taken into account if you submit a Docker image.

• The solver-command must behave as intended for all users, not just for a specific one.
• The solver-command must behave as intended independently from the current working directory.

Registration

To submit a tool, please follow the instruction at this repository.

Certification

We use CeTA version 3.6 for certification.
