LibEE visualization tool. LibEE shows the execution of each node and stacks them when they are executed at the same time to show the degree of parallelism. Colored areas mean that the cores are being used, and the white space shows inactivity. This example depicts a single evaluation frame of eight characters on a 32-core machine. During the evaluation, there are times when all 32 cores are busy, indicating that performance is limited by the hardware resources, rather than the rig itself or an evaluation engine. Because future machines will almost certainly have more cores, this means we are well placed to continue to scale performance of our engine with future hardware.
