Run the same job on Arm or x86

Moving a CPU-bound workload from x86 to Arm usually means rebuilding images, rewriting node selectors, and waiting on the platform team. In Domino, the chip is a Hardware Tier you pick when you launch the job. This demo relaunches a distributed compute job like Spark on Arm with the same code, data, and Environment, then compares the runtime and cost of each architecture.
