News: BIP91 seems stable: there's probably only slightly increased risk of confirmations disappearing. You should still prepare for Aug 1.

Most likely you used -T which stops you from using the menu options ...

If you compiled it yourself (and didn't use -T), then you didn't take note that configure told you CURSES was not available
(the curses.TUI message at the end)

If someone else compiled it - don't use their version, use ckolivas or my version (depending on Linux OS version)

If you are running on a 32bit linux, then you'll need to take note of how whoever compiled it for you (and the configure reply at the end)

i.e. supply more information about OS and who compiled it and what configure said.

Inaba were you able to resolve this? I'm running into exactly the same issue.

Ok, so I'm at stumped, maybe someone has an idea:

I have a W7 x64 box that I reloaded recently.  I loaded the ATI drivers and the SDK... firing up CGMiner, it mines just fine.  However, when I q out of CGminer, W7 will BSOD with a SYSTEM_SERVICE_EXCEPTION in atikmdag.sys.  I've Googled the hell out of it and tried all the suggestions and nothing seems to work.  I've uninstalled and reinstalled several different drivers versions, including 11.2 which I know worked with v2.4, v2.5 and v2.6 of the SDK.  Nothing changes the behavior.  

I realize it's not directly a CGMiner problem and something is wrong somewhere in the system, but bugger all if I can figure out what it is.  Does anyone have any ideas?  I've tried Driver Sweeper and reinstalled the drivers from scratch, but nothing works.

The system operates fine, I can play games, etc... and CGMiner mines fine.  The only time there is a problem is when I quit CGMiner, otherwise zero problems at all.  I'm completely stumped.

PS - this is mining with a pair of 6990's.


Anyone?

sorry if this has been asked again:
(U)tility is a sum of all the shares, accepted,rejected,HW?
is there any measurement (shares/min) only for accepted ones?

Pretty sure it was just Accepted shares. Since rejects kill your hashrate I would expect the U (SPM) to drop off too.
HW in my experience (BFL single) did change U (SPM). This would be caused by 15 seconds of doing nothing. I am not sure about GPU based work as I do not own profitable hardware for that.

I am sure Kano, Con or someone far better informed will let you know if I am wrong. I could be wrong and it is even semi-likely that I am.

Yes you are correct, U is accepted shares per minute.

You can calculate U directly from the screen: 60 * A / Elapsed
(Elapsed = now - Started: at the top)

Also, WU is the amount of 1 diff work done per minute by the hardware.

Note the other difference there: U is shares per minute, WU is 1 diff work per minute.
Share per minute is obviously affected by the share difficulty.

The API has all the numbers in it (both of: based on shares and based on difficulty)

The semi-official Bitcoin Pool Comparison Chart only shows 2 stratum pools, BTCGuild and Slush's.  Are there others?
Most pools are in the process of implementing it. Of the other ones that already have it, ozcoin is my favourite, but emc also does it (though with too unstable a variable difficulty IMO).

Come on now, lets be honest.  The variable difficulty isn't the problem here, Stratum is the problem: it's difficulty to work relation is broken from the ground up and needs to be fixed.  If the difficulty were too unstable, why can GW and GBT keep up just fine?  CGminer doesn't seem to have any trouble keeping up with it in GW, right?


If you're searching these lines for a point, you've probably missed it.  There was never anything there in the first place.

Um.. Oz has variable difficulty, I'm not seeing people complain it not working there.

New release - 2.9.5, 25th November 2012

Bugfix release.


Human readable changelog:

Fixed the crash when a GBT pool was used either as primary or backup when its gbt coinbase was very large.
Fixed the ztex submits lots of dupes bug based on an idea by luke-jr
Fixed the much larger amount of shares being leaked to backup pools
"getworks" will not be counted now from backup pools when they're just being used to see the pool is alive
Mips openwrt fixes


Full changelog:

- fixes target calc for mips openwrt
- openwrt needs roundl
- Get rid of unused last_work in opencl thread data.
- Do away with the flaky free_work api in the driver code which would often lose
the work data in opencl and simply flush it before exiting the opencl scanhash.
- Use base_work for comparison just for cleanness in __copy_work
- Remove all static work structs, using the make and free functions.
- Add pool no. to stale share detected message.
- Add info about which pool share became stale while resubmitting.
- Copy the work on opencl_free_work
- Add an extra slot in the max backlog for ztex to minimise dupes.
- Do not use or count the getworks submitted which are simply testing that pools
are still up. This was increasing share leakage and making stats not reflect
real work.
- Track all dynamically allocated memory within the work struct by copying work
structs in a common place, creating freshly allocated heap ram for all arrays
within the copied struct. Clear all work structs from the same place to ensure
memory does not leak from arrays within the struct. Convert the gbt coinbase and
stratum strings within the work struct to heap ram. This will allow arbitrary
lengths without an upper limit for the strings, preventing the overflows that
happen with GBT.
- libztex: Work around ZTEX USB firmware bug exposed by the FreeBSD libusb
- opencl: Use new dev_error function for REASON_DEV_NOSTART

I assume you mean on windows? I may have built it without adl support, lemme check

EDIT: yes my fault. Repackaged the windows binaries. Try redownloading.

New Windows build instructions.

http://pastebin.com/3pzivj32

Can someone with a Windows rig that has a Ztex test the new libusb section?
Need to know if you can mine successfully using libusb instead of libusbx because that is what cgminer will be going to in the future supposedly.

cut/paste ...

2.9.5
An Xubuntu 11.04 x86_64 executable is in my github downloads called cgminer-2.9.5a
https://github.com/kanoi/cgminer/downloads
(it also works on Fedora 16 and 17)

For anyone who didn't realise, it's just the executable file to put in place of 'cgminer'
Nothing else needs changing
First get and extract the full binary release from ckolivas and then copy my file in place of 'cgminer'

No problems so far on my '2xGPU' or 'BFL+2xICA' (90 minutes so far)
GPUs (687Mh/s) on solo and BFL+ICAs (1.6GH/s) on OzCoin Stratum with fixed 8 diff
(MMQ is doing new code testing)

The same configure options as cvolivas' binary version
In case anyone was wondering:
CFLAGS="-O2 -W -Wall" ./autogen.sh --enable-icarus --enable-bitforce --enable-ztex --enable-modminer --enable-scrypt
make clean
make


--

(and yes I made a 2.9.4a but didn't post about it)

--

sharky112065's post above is actually (indirectly) about ASIC.

I've rewritten the MMQ driver (as I've said a few times) and the problems with windows drivers included a problem with libusbx so I switched to libusb (thanks for help from the libusb developer) and the last problem was gone.
So when I finally get my changes into the main git - we need to use libusb not libusbx on windows.
Those changes include early code for the up coming ASICs.

Most pools are in the process of implementing it. Of the other ones that already have it, ozcoin is my favourite, but emc also does it (though with too unstable a variable difficulty IMO).

Come on now, lets be honest.  The variable difficulty isn't the problem here, Stratum is the problem: it's difficulty to work relation is broken from the ground up and needs to be fixed.  If the difficulty were too unstable, why can GW and GBT keep up just fine?  CGminer doesn't seem to have any trouble keeping up with it in GW, right?


stratum and variable difficulty are 2 different pieces of code
Ozcoin implemented stratum then coded the vardiff- not sure what you consider "broken" but we have it working fine, maybe the vardiff you coded before implementing stratum is the issue?

Seems to be your implementation of variable difficulty with stratum. It works fine on all the other implementations that were not influenced by GBT.

No, it's an acknowledged problem with Stratum.  The original Stratum design is flawed.  Difficulty is decoupled from work and that is simply an incorrect way to handle mining.  Difficulty and work are inseparable from a mining perspective.  The way Stratum handles is is entirely incorrect and needs to be addressed. This is not really in question, everyone involved pretty much agrees that something needs to be done about it, the only question is exactly what.

My implementation of variable difficulty is the original implementation of variable difficulty and has been working fine on both GW and GBT for months now. It works fine in CGminer on GW, it also works fine in GBT, Stratum and GW in BFGminer. The only implementation it does not work on is CGMiner with Stratum, but that's not really CGMiners fault as its' a design flaw in Stratum and Conman doesn't really have control over that.

I hope you realize that every other Stratum implementation throws away a bunch of valid work you are doing for the pool and it even throws away solved blocks if the conditions are just right because of the flawed difficulty design of Stratum.  So tell me which would you prefer?  Shares going POOF magically on your Stratum server of choice or you getting paid for your work?


If you're searching these lines for a point, you've probably missed it.  There was never anything there in the first place.
