[Blackbird0]

can asic usb block eruptor be used for anything other than mining BTC? or can they scrypt as well?

No. A SHA-256 ASIC cannot be used for mine a scrypt coin.

I've tried looking back and can't find anything on this- does BFG support or work with the Antminer U2?

It should.  Same everything except a slightly easier overclock and bigger heat sink..

A 2nd preview of the DualMiner driver for BFGMiner is now available for testing. There's a Windows download available here:

https://www.dropbox.com/s/dqbk841frvxdsmk/bfgminer_dualminer_pr2.7z

And you can clone the feature branch here:

https://github.com/nwoolls/bfgminer/tree/feature/dualminer-support

You can now mine SHA2 and Scrypt at the same time with two BFGMiner processes by using the --dual-mode argument. You can also specify a clock frequency using --set-device, e.g.:

Code:

--set-device dualminer:clock=850

Tested on OS X and Windows so far. Thanks in advance for the feedback!

 I wasn't sure since info seems scarce so far on the U2 and most of what I've seen refers to using CG. I'm not looking to jump camps yet!

I've already contacted Bitmain. They've been good about sending us dev samples in the past.

[ManeBjorn]

You can mine other SHA-256 coins.  Here is a good list of them to choose from.
I suggest checking exchange rates on them as well to decide what to mine.

I am trying to run bfgminer as a stratum proxy on my LAN so I can connect with my BE cubes, but I am not having much success. I downloaded the 3.10.0 source from github and compiled it. But when I try to run bfgminer with the --http-port option, i get "/bfgminer: --http-port: unrecognized option"

Did I have to specify any options with ./configure? I did not. 

What am I missing here? Can someone else help me out? Much thanks.

You need to have libmicrohttpd installed before you configure and compile BFGMiner.

Thanks. Now I seem to be getting disabled proxy:stratum "To enable proxy:stratum, install libevent 2.0.3+", when I do ./configure. After I received that error, I installed libevent-2.0-5, and re-ran ./autogen.sh, then ./configure again, but it still gives me the message that the proxy is disabled.

When you install libmicrohttpd and libevent there are generally instructions printed out on the screen for other steps you need to take afterward. You may need to run ldconfig and / or logout & back in.

So, trying to compile bfgminer in windows per those instructions in the readme file, I use MinGW and tried to install Git.  I did manage  to install git, but when trying to run the git clone from MinGW it says Git doesn't exist...Also the instructions in the windows-build.txt file says:
********************
** Install libusb **
********************

1.  Visit http://git.libusb.org/?p=libusb.git;a=snapshot;h=master;sf=zip
2.  Download and open the resulting zip file
3.  Extract the libusb-master folder to C:\MinGW\msys\1.0\home\USER
4.  Return to the MinGW Shell
5.  Type the following (replace XYZ with actual identifier):

   cd ~/libusb-master-XYZ
   ./autogen.sh --disable-debug-log --prefix=/MinGW
   make
   make install

but the website doesn't exist so I can't install libusb like that.  is there another libusb to install?

Oddly enough, I am able to run the bfgminer with --http-port option, and my cubes connect to it as stratum. High reject rates though (20%), may be the pool.

Not that I have much time, but I did the following for you.  And I could not get the stats from BFGMiner after the q because it just ABENDs when I quit. ABEND=Abnormal End, I am old IBM Mainframer programer (have had a email address since 1969).

I haven't diagnosed for differences, and I currently don't have the time since one of them is working. The box is a ASUS Sabertooth 990FX r2, 32 GBytes of RAM, Phenom II x8 @4.02 Ghz, running Windows Server 2012.  The box is part of my web hosting business.  The GPU is a R7 260x. Since you asked I gave it to you.

What was hashing with a passion on Scrypt was not so productive on BGMiner, apparently.  Not very scientific, I just looked at accepted per minute.

Do you have time to be scientific? If so:

What hardware are you using?
What arguments are you launching BFGMiner with?
What arguments are you launching SGMiner with?
Can you run each for 15 minutes, then hit Q, and then Copy & Paste the summary here?

[nwoolls]

Two things I noticed. First of all, you are using different settings for BFGMiner versus SGMiner. You are using Intensity 17 with BFGMiner and 18 with SGMiner. You are also specifying thread-concurrency with SGMiner and not BFGMiner. This should make a big difference when set correctly.

"intensity" : "17",
"vectors" : "1",
"worksize" : "256",
"lookup-gap" : "0",
"thread-concurrency" : "0",
"shaders" : "0",

"intensity" : "18",
"vectors" : "1",
"worksize" : "256",
"lookup-gap" : "0",
"thread-concurrency" : "8000",
"shaders" : "836",

Additionally, CGMiner (and it seems SGMiner) report the work done by weighing it with diff 1. So you will see inherently different numbers for Accepted, Rejected, etc. when comparing to BFGMiner. If you would like to have BFGMiner do the same so you can compare things more closely, run BFGMiner with the --weighed-stats argument.

Edit: Luke let me know that even with --weighed-stats it may not match up. Best bet is to compare the # of Accepts shown in the BFGMiner UI with the total # of Accepts shown when you quit SGMiner (75 in your post, not 2400).

Now from another post on this thread about your MultiMiner, I am going to check this out since I have one hub with USB BlockEruptors, a ANT U1, and a BE Cube from ANT.  They are currently on separate boxes, I could consolidate.

Thanks

sgminer's changes, as far as I can see, are shit.  I'm using either bfgminer 3.10.0 or cgminer 3.7.2 for my scrypt mining - those two miners actually work.  sgminer doesn't work at all well.  I think they're adding 24" chrome spinner rims to an AMC Gremlin.  

I use a mix of HD6xxx, HD7xxx, and R9 GPUs on Windows 7.

+1, I have not yet tried out SGminer, but early versions of cgminer are what I still use when I want to do things such as solo mine Scrypt alts. I gave it a shot with BFGminer for Scrypt mining and had it running fairly well after some initial issues, but since I have a large farm, and need the capability to solo mine for profitability of newer "crap coins", I can't do that without issue with BFG yet.

I don't understand the "rift" between SGminer and BFGminer though, I don't know why there always needs to be drama on any similar products. Human nature? I don't think Apple is going to join Google because they provide similar services, so how about we live and let live?

Much of the confusion over supporting BFGminer has always come from Luke's past comments on all Scrypt coins, and while they may have been retracted and there is a larger development team now committed to that area, it doesn't change the statements. CK said similar things, and then dropped support. I'd venture to say that the Scrypt community needs someone committed to that area to lead up a project, and while many here say they should just join and contribute here, I'm not fully convinced that a new project isn't a better thing for the community.

I'm also a believe in completely separate miners for each protocol, however ASICs with mixed mining have made that unlikely.

I think one of the bigger problems with scrypt mining in general is the fragmentation of drivers vs current software.  Many people with large rigs (or even smaller ones) found older driver configurations that work great, but when combined with newer drivers those configurations do not function as well.  Add in the changes to AMD's SDK and compiling, and we are not seeing scrypt CL advance and keeping pace with new drivers in both stability and performance. 

Without a willingness to optimize for the newest SDK's (because of reduced performance or reprieved reduced performance/stability) and try to increase performance using future centric thought (modern SDKs and modern driver support), scrypt is stuck in a rut as far as gpu performance.  If anything, scrypt asics will become desirable simply for "plug and play" that should do away with these complicated factors.

If I could get my old 5770 to mine without rolling all the way back to 2012 Catylist drivers, I'd be mining scrypt with it right now.  However, seeing as it is my only desktop graphics cards, I want my gaming and scrypt too, and I can't have both (SGMiner, or BFGMiner be damned, neither work correctly for me).
