MultiMiner: Any Miner, Any Where, on Any Device (Free, Open Source, Cross Platform)

[nwoolls]

So CGminer will no longer be supported, even just locking the version down for GPU's of the last supported version?

It will remain working with the v1.4 line for MultiMiner. The device detection in v2.0 is rewritten.

The problem (among others) is that device detection and device specification for bfgminer and cgminer is going in two wildly different and incompatible directions. Both cgminer and bfgminer are starting to return different information for the -d? output, and both are starting to require different input arguments for specifying individual devices reliably.

Personally, what I would like is for these miners (bfgminer, cgminer, cudaminer, cpuminer, whatever) to have a standard way to:

• List available mining devices
• Mine with a specific list of devices
• Gather output and details on mining progress

If Luke and Con felt up to doing this I think it would rock for both me and other GUI authors.

If someone wants to help contribute to the source code and keep cgminer compatibility that works for me too.

And more...

[nwoolls]

Here is another unofficial 2.0 release for any adventurous folks to test:

https://www.dropbox.com/s/3651qrrluin9oq9/MultiMiner-2.0.0.51.zip

Again, this requires bfgminer built from currently unreleased Git sourcecode:

http://luke.dashjr.org/tmp/code/webisect/webisect.php?dobuild=bfgminer

Changes in v2.0 include:

• A Restart button has been (re)introduced when mining
• Mining is no longer automatically restarted by MultiMiner due to configuration changes (use the Restart button instead)
• Added the ability to expand and collapse the amount of detail shown on the main screen
• Devices are now grouped by kind (GPU, CPU, USB, Proxy)
• Added the ability to view mining devices in a list, tile, icons, or details
• Newly discovered devices default to Bitcoin
• Separate processes are used for mining GPU & CPU versus USB & Proxy (for stability)
• Added support for CPU mining (if it is enabled in bfgminer)
• Improvements to the Getting Started wizard
• Previous mining history is loaded on startup
• It is now possible to select multiple devices
• It is now possible to to mine several different coins across several different USB devices (previously this was troublesome as USB devices may be in use)
• It is now possible to mine with both Block Erupters and Blue / Red Fury simultaneously
• Per-device settings now do a better job of "sticking" when devices are added or removed
• Improved device descriptions
• Support for cgminer has been removed
• Support for bfgminer 3.7 has been added (and is the minimum supported version)
• MultiMiner will no longer prompt to automatically upgrade to major new releases (e.g. from 1.0 to 2.0)
• Migrated to Semantic Versioning (major.minor.patch.build)

Hello,

Just say that as an idea but if Multiminer could manage from one place (desktop computer, mobile), many mining hardware and / or Rigs (many peoples still uses rigs for ltc or gld), it could be great.
I saw CGRemote ( http://manotechnology.blogspot.fr/p/cgremote.html ) doing that kind of thing.

I planned to build 4 rigs soon. It could help a lot.

Well, if it's not planned, you'll have to do it !

[nwoolls]

Just say that as an idea but if Multiminer could manage from one place (desktop computer, mobile), many mining hardware and / or Rigs (many peoples still uses rigs for ltc or gld), it could be great.

Currently you can use MobileMiner to monitor and control your multiple mining rigs. The future plan is to allow MultiMiner to detect other instances of MultiMiner on a network and allow once instance to control all of them.

I have always used CGminer. I have been doing a little reading on BFGminer since MultiMiner wont support it anymore. I am not 100% sure so just thought I would ask, Does if fully support scrypt mining?

I have always used CGminer too, and I tried BFGminer today on one rig, as I want to continue using multiminer, but the hash rate was about 40 kh/s less per card with the same settings. I didn't spend much time tweaking, but I reverted back.

Sad to see with so many coming into Scrypt mining now that we're stuck with no more updates. Hoping that the Scrypt fork gets off the ground, wish I still had some programming skills.

In my opinion there's no need for a fork. All that is needed is for someone to contribute to bfgminer. It is only if nobody decides to contribute to bfgminer that scrypt and GPU support will probably be axed from that as well.

There's lots of folks on the Litecoin forum forking cgminer and I get emails from folks also interested in forking. To me it just seems like a much more straight forward and beneficial path to improve the scrypt support in bfgminer.

Personally, as the developer of a GUI miner, I'd much rather just support one miner backend. Version 2.0 will have many more features because I don't have to code to the "lowest common denominator" backend. Even if a fork of cgminer were to become popular and widely used, I'd have to see a significant advantage to switch back to supporting multiple backends.

BFGMiner is great, but saw recently it have some tweaks and improvements and code purposes still required, especially on Mac. It was impossible to make it work last week with scrypt & CPU/GPU on a OSX. LukeJr said coders are free to come and improve BFGMiner on Mac computers.

I'm not sure what you are referring to - do you have a link?

CPU mining is not enabled by default in bfgminer or cgminer (though either can be recompiled with it enabled). I just tried scrypt mining with bfgminer on my Mac and it worked fine. Check out the steps in this article:

I posted this is the support forum, and apologize for double posting. After almost 90 views and no replies I'm taking some measures.

MultiMiner detects my block erupters, but only utilizes one of the two. BFGMiner by itself will run both, so MultiMiner not running both is baffling. I've had them hooked up into my front USB ports, with success, and my USB3 ports on my motherboard directly, also with success.

I've tried both ICA and BES devices under the settings, both worth fine (well, with the one that's hashing).

Any suggestions?

Post the arguments found on the Process Log screen compared to the ones that you are able to use to successfully mine with both.

Also try the recent link to an unofficial v2.0 build with an unofficial v3.7 bfgminer as these both fix the way multiple devices are started.

[ford0415]

I don't use any arguments with BFGMiner 3.6 (I just run it, and add the devices myself erupter:all). After that I have it set for Balanced, 256 workload, 2 GPU threads, with a 6 intensity.

I've tried MultiMiner 2 and it crashes on my end.

This is what I'm getting for the Process Log

-I D --scan-serial all --scan-serial opencl:auto -o coinotron.com:8322 -u USERNAME-p PASSWORD -d 0 -d 1 --api-listen --api-port 4029 --api-allow W:127.0.0.1, -T

Just for reference, I *DID* blank out my username and password.

Can you please post the full crash text (copy & paste)?

Please try running bfgminer directly with:

Code:

bfgminer -I D --scan-serial all --scan-serial opencl:auto -o coinotron.com:8322 -u USERNAME-p PASSWORD -d 0 -d 1

This is the same arguments MultiMiner is using. Does bfgminer mine with both ASICs?

Just for reference, I *DID* blank out my username and password.

No need to unless you are re-using passwords. This is just your worker name and password which is of no use to anyone else unless they want to mine for you.

[ford0415]

I just tried BFGMiner with those arguments, and well... only one erupter works.

Here's the crash log for MultiMiner v2...

Here's the crash log for MultiMiner v2...

Just to clarify: you also downloaded the version of bfgminer 3.7 linked and installed that under the Miners\bfgminer folder? MultiMiner v2 won't work if you just let it automatically download bfgminer (as 3.7 isn't out yet).

[ford0415]

I did download 3.7 and extracted it to the miners folder for multiminer v2.

I am having an issue getting multi miner to start on OSX mavericks 10.9.  I've installed mono 3.2.4 and Xquartz 2.7.5.  When I start MultiMiner I get the screen asking to download cgminer and bfgminer, whichever of the three options I select, the window goes away and mono-sgen goes to 100% cpu, and no further windows appear.  At this point the application says "not responding" and no windows appear.  I don't see any output in the console, and I can't seem to find a log file.

 I've looked at this thread and the mono mailing list and can't find any similar issues.  Can someone point me to some debugging tips, or if you have an idea of what the problem might be, that would be fantastic!

Thanks,

You could try installing bfgminer or cgminer yourself first. MultiMiner only installs it if not present. There are instructions here: http://thread.xgminer.com
