Double Mersennes Prime Search

Workunit duration calculator

OK, you read some of the DoubleMersennes pages, you understood some of the backgrounds of the search and learnt its history.
Now what? You found yourself willing to help the search, but there are still some questions you need answered, i.e. how many days will my search require?

There are six values you need to input: 

	Mp            
	From k        
	To k       
	Threads    
	MHz        
	SW

Trial-factoring MM61 from k = 1,000,000,000,000,000 to 1,500,000,000,000,000 with software mmff requires 0.5261 days on a 3800 MHz PC.
