Title: is the number of stale/duplicate shares normal? Post by: tarui on July 30, 2013, 10:05:47 AM ok not sure if this is relevant, ever since i switched to PPLNS from PPS i've been getting quite a bit more stale shares but here's the overall figures

But doesn't the dupe count seem really high in proportion? Title: Re: is the number of stale/duplicate shares normal?

I'm thinking 1% to 5% Hardware Errors which you would see in the mining software. But, .46% stale is still fine. Sam Title: Re: is the number of stale/duplicate shares normal?

Title: Re: is the number of stale/duplicate shares normal? Post by: -ck on October 08, 2013, 08:16:16 PM Dupes should be close to zero. Earlier avalon firmware had design problems that caused dupes and updating firmware should fix it.

You should be happy, I have a 2% stale share, tried many method and still won't reduce. Title: Re: is the number of stale/duplicate shares normal? Post by: eleuthria on October 10, 2013, 02:24:34 AM 0.46% stale is quite usual for an Avalon these days. One thing to keep in mind is that stale rates will scale roughly in proportion with network growth rate. So when you're at a period of 20-30% network growth rate, you can expect roughly that many more stales than normal. So if 0.40% was your nominal rate, it may be 0.48-0.52% when network is growing rapidly.
Dupes are often firmware related, but can also be network connectivity (resubmission of a share due to lack of response in a timely manner). I know FPGAs were big culprits of duplicates, but they weren't actually *wasted* work, it was simply that there was some kind of firmware bug that caused them to report the same nonce information in certain scenarios where no solution was found when the nonce range was depleted. My Avalon lately has been mostly clean on dupes with later firmware, generally a completely insignificant amount. It may be network connectivity, since my Avalon is on wireless across the house, with a microwave in the middle :P |
