I wonder does quick build has the ability that to trigger the same task on the same agent in the mean time? Because for my agent, it has two site CPU, so it can run the same test on different site CPU in the meantime, but from the quick build side, if I trigger the same task on same agents, the second one will start until the first one finish.
QB can not run same task concurrently on same agent, as otherwise they will access same workspace of the agent concurrently. To address the issue, uou will need to install multiple build agents on the machine to make use of multiple CPUs.
