Discards
-
I get the opportunity to mine on different platforms throughout the day as resources become available and wanted to see what was going on so I have set up a Raspberry Pi as a Anubis server, I might write a how to if anyone is interested?
So now I get to see a bunch more information about whats going on and I have a couple of questions/observations…
What are Discards, and what is an acceptable amount?
Now Anubis is running the BAMT page shows 0 Kh/s but cgminer shows the expected 700Kh/s and the pool is reporting about right
Anubis doesn’t seam to display the Mh/s 5/sec as anything other than 0
Any info you can offer would gratefully received

Discards = stales.
When a block is found, the solution required to mine the next one changes. As a result, any work which you might have done on the old block is discarded.
In theory, this should never happen, because as soon as a new block is found, the pool should notify your miner client and prevent any loss of work. In practice, it happens because of network lag: The more lag, the longer you’ll go doing work without seeing the update.
1% is generally considered an acceptable rate for stale shares on most networks, but it varies from pool to pool and coin to coin. Anything more than 5% and you might want to consider a higher difficulty if the pool offers user selectable vardiff: A higher difficulty means more time between shares found, which means more time to see a new block before finding a stale share.

Cheers for the reply Kevlar :)
Going to go and do some more testing later on this one as I think my % is very high based on the information you have, but the pool is still counting and paying out for the work I have done, so how does that work?
