Title: Multiple miners on one card?
Post by: dikidera on May 27, 2011, 08:39:15 PM
I have just one 5850. It pulls ~273 Mhash/s at stock speeds. Now, i know that solo is near impossible even with dual 5970 and will be even more so, however do you think that the chance of finding a block increases if you have multiple instances of a miner running? I have 4 currently on my 5850 and the speed is somewhat divided for every miner.

Assuming that a quad 5970 uses the same method, don't you think the probability get's increased by a small fraction that you will find a block faster than with one miner? I mean it's basically the same thing with pools. Every worker requests new works, increasing the chance of the bitcoind sending the winning hash.

One miner, one GPU.

The GPU is the GPU. it's the program i am referring to as a miner(cause it it's the one doing to job more or less) which on my case is poclbm(GUI)

I have tried this myself, and it doesn't work well. You're basically slowing down the hashing so much, you will be going slower on each instance. Think of finding the block like a lottery. 1 miner/GPU set would enter many times quickly, or you can divide it into four people entering slowly. Either way, you would come out with the same amount of chances.

I've been monitoring the progress and the most i've lost is 4-5 shares less than usual. Sometimes i actually get a few more.

Still: if your GPU makes 1000 hashes/sec it doesn't matter if there are 4 miners with 250 each (probably less cause of overhead) or 1 Miner with 1000. Each Hash has a Chance of winning, Not related to Number of miners
