This chart shows the relationship between the number of units in the pool and the amount of processing power available. These charts shows the pool capacity of the active members over the last year.
A 'Thread Stone' is defined as 1 Thread (Each thread works on it's own downloaded problem. A multi-core processor can work on multiple problems at the same time) times 1 Whetstone MIPS (A measure of processor speed). Theoretically, the larger number of Thread Stones available in the pool means that there is a higher capacity for work to be done.
