Hi Guys,
Can anyone help me out.
When I run the "Devs" command on an SP30 miner (running most current firmware) I get the following output.
av=4445838.29,MHS
5s=5923594.28,MHS
1m=5187361.37,MHS
5m=4678246.84,MHS
15m=4526365.21
I notice that the av number seems to be the only number that is accurate. Can anyone tell me what the other number are? I would like to know why the 5s shows almost 6TH/s in this example.
Thanks guys.
Statistics 101?... That aside
As the measure time interval decreases variance increases e.g. A 5 second average reading has much higher chance to vary above and below the expected value than a 5 minute window.
This is in part due to the manner in which the mining software calculates hashrate.
A personal example. I have a particular miner which consistently performs at 500Gh/s both in cgminer avg and pool but I e observed the 5s avg vary from 200G to 1T
Ok So my real question is, does av show the current (live) hash rate?
I use
http://www.multiminerapp.com/ to monitor the SP30's and it generally works great. The one problem is that it consistently reports the miners hash far to high (between 5 - 9 THs).
The software polls the miner via the CGMiner api with the DEVS command to get the stats. I am trying to ascertain what in the returned data is the live hashing speed so that I can get the devs to ensure that is what is being recorded by there software.
I hope that makes sense. Thanks again guys
