This change reduces the I/O size per job, but it keeps the total I/O size regardless of the number of CPUs. This will keep test case runtime reasonable on systems with hundreds of CPUs. As for the test case nvme/045, it tests re-authentication. I don't think it requires total I/O size proportional to number of CPUs. As for the test case nvme/047, it exercises different queue types (write queue and poll queue). Does it require total I/O size proportional to number of CPUs? Daniel is the test case author, and I guessed he is ok with the change.
