ckolivas / kano - Can you tell me which is a better stat for measuring. Its is MHS or Work Utility?

From your readme: WU:  The Work Utility defined as the number of diff1 shares work / minute (accepted or rejected).

On some units at 375 Mhz overclock I get a higher work utility but lower MHS than I do at 350 Mhz. (and on other units I get a what I feel is good scaling). I am not sure how work utility is calculated or if its just an estimate.
My theory was if Work Utility provided a better stat then I would target that vs MHS. I just have so much variance so was trying to figure it out. Any help appreciated!

Thanks!
On avalon:
WU is accepted + rejected + nonce errors.
MHs is accepted + rejected

So you're better off with MHs for that particular hardware and how it measures those values.

Problem is not with that pool, it works fine in signle-pool mode, problem is with cgminer.

Is it the same for BFL ASICs, or are HW errors included in their hashrate? I thought they were included in the hashrate for all devices, it's quite confusing if they are included for some but not for others.

You're right, it is confusing and they are different. It has to do with the fact that on one device, BFLSC, I know precisely how many "hashes" were attempted by the device, while on the Avalon, the best I can do is estimate based on the amount of nonces returned due to work being aborted a random proportion through its completion rather than at the end. If I start counting the hw errors as hashes on the avalon, I could get a flood of hw errors in a row, as sometimes happens, that make the hashrate look like it's spiked upwards.

It's painful with every manufacturer doing something different and there being no meaningful way to unite a lot of these into "standards".

New release: version 3.3.1, 26th June 2013

Hotfix release. Last minute bug went into 3.3.0 preventing BFL SC singles from working as planned Roll Eyes
Note now there are avalon firmware images in my directory as well, with the latest version.

Human readable changelog:

- Bugfix for BFL SC singles and minirigs which prevented them working.
- Bugfix for the usb wildcards 1:*
- Increased target temperature on Avalons to 50 since 45 was overkill
- Added overheat temperature cutoff to avalons
- Added dynamic automatic overclocking to avalons with --avalon-auto


Full changelog:

- Add an avalon-auto option which enables dynamic overclocking based on hardware
error rate for maximum effective hashrate.
- Add an --avalon-cutoff feature which puts the avalon idle should it reach this
temperature, defaulting to 60, re-enabling it when it gets to target
temperature.
- Change default avalon target temperature to 50 degrees.
- usbutils - incorrect test for * in bus:dev
- Redo +1 fix in bflsc.

Nice! But is there a way you can implement 5MH steps from 300 to 375? That would get more on some configs. My avalons run fine on 365.

Tip is on the way  Wink

EDIT: Holyshit!!! it's already in there  Cheesy Cheesy  Another Tip send!!! Thanks!

This is so awesome!
Getting my new avalon just today when so much new functions are released!

Thanks a lot Con for avalon-auto option. Is it possible to create something like avalon-limit frequency option?
One of my avalons has freezing controller board at 350 MHz, but during avalon-auto it worked around 330-340 without problems, so I'm currently locked at 325  Sad.

What does the error "-3" mean when I have a BFL FPGA Single with the WinUSB drivers installed, but CGMiner says it can't open the device?

Tips? 1crazy8pMqgwJ7tX7ZPZmyPwFbc6xZKM9

ASICMiner USB Block Erupter
cgminer 3.3.1

I get

AMU0: Comms error (werr=-7 amt=0)



cgminer 3.1.1 works fine.  I couldn't get 3.2.1 to work.

I'm starting 3.1.1 with --icarus-options and --icarus-timing and -S and the pool info.

I'm starting 3.3.1 with just the pool info.

Yay zadig utility fucked up my ability to connect to my FPGA BFL MiniRig.  Sad

Is there a tutorial out there somewhere?  Maybe this can't be done on an older XP laptop?  Was working before just fine prior to this winusb garbage.  It appeared to install correctly but no com ports are recognized now.

Easy to undo.
Go under system, device manager, USB serial bus controllers. The device will be there. Tell Windows to upgrade the driver. It will install the old serial one. Open Zadig, show all devices, and administrator. use WinUSB and the version of Zadig in the FPGA-README to try again. It will work.

I went to Linux and found far less errors. Raspberry Pi's are cheap, capable and low power. Personally it was the best <$60 I spent case included. Good luck!

There aren't supposed to be COM ports ... read the FPGA-README.

cgminer 3.3.0 under Ubuntu 13.04 - 64 bit.   Runs fine with 11 Erupters initially, but after about three minutes, it locks the system up so hard that I have to power off and back on to get it to respond..

cgminer 3.1.1 works, (after I create a symlink for libusb.so.0) but the devices change to SICK one by one over a period of time until they are all down.

Any suggestions?
