I'd like to chime in and say that after upgrading to CGminer 2.5.0, I'm getting an increased number when dividing DW by Q while solo mining. Doing this USED to get me ~ .003 - .006 in BFGminer 2.4.4. Now I'm getting above .01 on 2 different machines, both running Win 7x64. To be honest I'm not even sure doing this math means anything while solo mining, but it's what I've been doing to try and see how much work has been useless, and I can't see it being a good thing. Running 11 singles with a couple odd gpu's in 2 different cmd prompts across 2 machines.

Do these numbers actually mean nothing when solo mining or..? I figured I'd post this just in case. Maybe it was for naught Smiley

I don't think it means anything.
AFAIK, DW is work requests that have been discarded for whatever reason. Work that has not be started, just retrieved from the server then thrown away.

I typically get 10-15% discards.

Yes, I believe I spoke too soon. After closer inspection, it seems upon detection of a new block, it dumps everything under - I'm guessing - ST to DW. Just getting rid of old work that has not been processed yet for a block that matters none anymore.

For some reason it seems as though one of the miners always takes about 5 or 6 seconds longer to realize there's a new block. Maybe because of the lack of long poll, the prompt with higher hash speed will always notice first because it needs to send something to realize it's not longer relevant. This would suggest that if you have to use multiple computers to host your gpu's/devices, you should try to spread hash speed as evenly as possible. For solo mining of course, where with long poll this wouldn't matter. At least this is my guess. Not related to CGMiner I know, but I wanted to put it anyway Tongue

After running 2.5.0 overnight, the reported rejects are only 0.5% now vs. 1.5% before (with the BFL singles).

Thanks for the feedback. That was one of the improvements mentioned that I finally got sick of the arguments over and coded up the solution myself. Glad it works for you  Smiley

That's (partly) because they're not reported. There's also about as many valid shares being silently dropped, as the shares actually being prevented.

Cgminer: 2.5.0
It is still hanging after a while if NOT use --no-adl ... It can be ever fixed somehow?
Or can I do something to debug that?

I couldnt easily find this anywhere, but whats the proper json format for the new "restricted access" feature? vs full access for remote API accessing of cgminer?

Being a windows driver bug, there really is nothing I can do about it apart from suggesting trying a different driver version. I'm surprised you hit this bug so quickly after 2.5.0 though since most people find it hitting after a week of running.

Mayeb add some async watchdog that will detect stuck miner (lock over 1 minute), ignore ADL for a while using safe settings (fan on 99%) then try restart it?

Just built this on OSX 10.7.4, but I have trouble getting --enable-bitforce to work, and beeing a newbie on these kind of things I would like if anybody can help. If I can be of any help, I built it with these steps:

  • installed Xcode via App Store
  • sudo port install pkgconfig curl +ssl
  • ./configure --enable-cpumining
  • sudo make install

The error I get when trying with --enable-bitforce is:

Code:
 CC       cgminer-fpgautils.o
fpgautils.c: In function ‘serial_open’:
fpgautils.c:214: error: ‘CBAUD’ undeclared (first use in this function)
fpgautils.c:214: error: (Each undeclared identifier is reported only once
fpgautils.c:214: error: for each function it appears in.)
make[1]: *** [cgminer-fpgautils.o] Error 1
make: *** [install-recursive] Error 1

EDIT: Btw: You must use -w 64 because of the OSX OpenCL bug. And, if you have two adapters, it seems that the weaker one is device 1, and the discrete is 0. E.g. in the mid-2009 MBP: Device 0 is the 9600M and device 1 is the 9400M.

I'm not really sure exactly what you mean by your question - but the API-README contains all the info about the API ...

Edit: If you mean the command line parameters then they are in README for the basic command definitions and more details in API-README

CBAUD is part of termios.h - which is included by termio.h - the same place B115200 comes from.
The actual definition of both of them is in bits/termios.h

Find where B115200 is defined and CBAUD should be in the same place:
 grep B115200 /usr/include/*
 grep B115200 /usr/include/*/*
 grep CBAUD /usr/include/*
 grep CBAUD /usr/include/*/*

If it's missing then all I can guess is that OSX has done something very strange ...

The addition of CBAUD was to fix an old issue that setting the serial BAUD rate should only change the bits that represent the BAUD, not zero everything else.

Hi, What caused this after cgminer-2.4.3-x86_64-built? Have no any problem before 2.4.3. Thanks!
Quote
./cgminer: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.15' not found (required by ./cgminer)
./cgminer: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.14' not found (required by ./cgminer)
That's why I recently added xubuntu 11.04 builds of the binary in my git download for anyone who still uses ubu 11.04 or similar and doesn't want to build from source:
https://github.com/kanoi/cgminer/downloads

Kano, sent some bitcs your way for saving me an OS upgrade. Seriously, why is it required to upgrade your OS for a new version of software? Shouldn't there be an easy way to just get the new GLIBC installed on an old version?
