Title: What does "U" represent in cgminer?
Post by: c789 on July 07, 2013, 09:42:27 PM
I checked the readme, and while it explains what "WU" is, I couldn't find what "U" represents. What does it stand for?

On a somewhat related topic, I mine with 2 pools using my one machine. Here are my readings from the 2 pools:

Pool 1
-------------
U:    21.7/m
WU: 78.3/m

Pool 2
------------
U:     5.2/m
WU: 76.5/m

Everything is the same except for the pool. Why is there such a large difference in "U"?

If you can't find it in the README, check the first post in the CGMiner thread. There's tons of info there.

Each column is as follows:

U:   The Utility defined as the number of shares / minute

WU: is how many diff=1 shares would be submitted if CGMiner submitted all shares. Looks like you're using varrdiff, so the actual number of shares you're submitting are going to be lower. This is the U: number.

Thanks!

So in my scenarios, I should be using Pool 1 since it has a much higher "U"? Any idea why it's so much higher?

The two different pools are using variable difficulty and they have different targets for that difficulty.  Your WU:, aka Worker Utility, or diff 1 shares, is the same and the pools will convert your shares back to diff 1 to pay on.  So both pools will pay on about the same number of shares.
