For HPC clusters, it is important that they are scalable, in other words that the capacity of the whole system can be proportionally increased by adding more hardware. However, as Gustafson pointed out [2], in practice the sizes of problems scale with the amount of available resources.

Non-functional testing examines how a system operates rather than looking at specific functions or behaviors. To reach better test coverage for a product, we should examine the whole system. Data from non-functional tests can define optimal to stressful loads on a system. Both functional and non-functional tests are essential.
