CPUUtilization Based:

	1 week ago	1 week ago + 1 hour	Now	In 1 hour (Prediction)
Avg CPU avg_cpu	50%	45%	52%
Num Nodes nodes	2	4	2
See if the present is matching the past
Total CPU total_cpu = avg_cpu * nodes	100		104
100 and 104 are close enough together to assume that the future will match the past
Calculate total cpu for 1w ago + 1h
