Due to the latest developments on the factor hunting I will keep running my k=5 ranges because right now most of all is done manually outside my home, only running two cores at home. It is a very painful process to remotely control the linux machines with the internet connection I have at home.
As soon as the new sieve file is available I will feed the computers with it. Still to feed range from 4210-4240. The rest in underway.
