Modular Reasoning about Error Bounds for Concurrent Probabilistic Programs - Formalization Artifact This artifact contains the Rocq development of Coneris, which accompanies the ICFP 2025 submission "Modular Reasoning about Error Bounds for Concurrent Probabilistic Programs". Contents The file coneris-vm.tar.gz contains a virtual machine image containing the Coneris repository with all the dependencies installed. The file coneris_repo.tar.gz contains the same Coneris repository. Usage Please refer to the README.md in the coneris-vm and coneris_repo folders. In summary, after initiating the VM image from coneris-vm, cd directly into coneris and directly call make since all dependencies are installed. Otherwise, follow the instructions to install opam, rocq, and other dependencies on your own machine to compile the files in coneris_repo. Comment When compiling the files in the virtual machine image, please use make instead of make -j N due to memory constraints in the machine.
