While mining with multiple devices GPU, FPGA, etc. at home/work/school, does each device work on its own block or can you combine the resources of each mining device into 1? Say if each device can mine at 1GHash/s, 5 devices for an overall 5GHash/s between all devices. Can you set it up to where that 5GH/s is used on 1 block instead of 5 blocks? As it would reduce the block validation time?
If you can combine the resources of the solo mining operation, I assume setting up a private/solo btc pool is inorder. Would you use long polling in this instance or not?
