Scientific Computing is constantly evolving, relying on technologies increasing in complexity. Codes produced in that field require testing and validation to assess their performance and reliability. This additional but inevitable task is often of low direct added value compared to the deployment costs. Yet multiple solutions dedicated to testings, including some HPC specific, are currently available -- our solution has unique specificities. "Parallel Computing Validation System" (PCVS) is an HPC-aware YAML-based job orchestration tool. It offers the unique capability of retargeting tests, decoupling benchmarks and execution environments. This way, it allows the same job set to be re-run to compare two standards without modifying test specifications. This validation set may be scaled automatically depending on available resources, whether the process runs on a single node (like a workstation) or a thousand-node supercomputer. Beyond a one-time shot, PCVS can log several successive executions of benchmarks for browsing, inspection, and post-processing through a dedicated Python interface. More than a metric, PCVS can build validation trends, providing better visualization to track project evolution, leading to better software quality.
