Figure 1.

Number of worker CPU cores allocated from EC2 versus throughput measured in experiments per hour: that is, the reciprocal of the wall clock time required to conduct a whole-human experiment on the Wang et al. dataset [5]. The line labeled 'linear speedup' traces hypothetical linear speedup relative to the throughput for 80 CPU cores.
