So, i have a question about primecoin mining, how exactly does each block gets mined.

Are basically all blocks open until they are solved? In other words, if my miner finds a block and is working on that block to solve it, then can Joe Blow's miner finds that same block and solve it quicker and earn the coins? Or do i have a flawed understanding of a "block"?

What Im getting at, is it better (not taking electricity into consideration) to have a bunch of separate slower pps computers (or miner instances) or one beast computer (one mining instance) with the same combined pps as all of he smaller ones?

I would think, that if a little luck is involved in finding blocks, then the more instances, the higher your probability of "finding" a block right?


Thanks, I'm a little bit of a mining noob, just trying to learn the terminology and technology better.

Thanks,
