  With the rapid development of quantum hardware technologies, benchmarking the
performance of quantum computers has become attractive. In this paper, we
propose a new aspect of benchmarking quantum computers by evaluating the
limitation of hardware utilization using a multi-programming mechanism -- a
technique that simultaneously executes multiple circuits in a quantum machine.
This is the first attempt to compare the evaluation of multi-programming on
trapped-ion and superconducting devices. Based on the experimental results,
performing multi-programming on a trapped-ion device demonstrates better
results than a superconducting machine without losing any fidelity to
independent executions.
