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

[nightengale]

I use information from the CoinChoose "LTC Profitability" tab for my mining -- is it possible to use MultiMiner to mine with a strategy based on LTC profitability?

I have to say I have never clicked that tab in CoinChoose! That's a cool option. It looks like a very simple switch in their JSON API and I'd be happy to include this in the next update.

Thanks for the feedback and kind words.

Thanks so much for looking into it!

The app has been rock solid and I absolutely love it. I use it to switch between three coins currently, but when it switches, often the coin name will change correctly on the display, but the previous coin stats (difficulty, price, profitability, etc) will stay the same. It's nothing that impacts anything at all, and it certainly isn't a big deal, but figured I'd mention it.

Imagine my disappointment when I found Litecoin difficulty wasn't actually at 2 (was mining infinitecoin prior).

BFGMiner 3.2.0 is out, but MultiMiner hasn't popped up a message suggesting to upgrade.

EDIT: I manually updated, and now MultiMiner is saying that "3.1.4 is available (3.2.0 installed)" For some reason it thinks 3.1.4 is more recent?

Hmm.. What about making it an optional item, selectable by a menu item in the "Advanced" menu, "Show number of devices." Kind of how you let people choose if they want to see the history/API/Process log?

It's possible, but I'm also trying to reduce complexity of the code. What advantage would individual device #s give you over a total device count? It may be something I'm overlooking.

This is because Luke forgot to put the latest version in his Testing folder, which is where I pull from. We've chatted about it and he assures me that folder should contain the latest version, but the past few times I've had to ping him (which I just did again on IRC).

Interesting. I've seen one other user mention this months ago but been unable to reproduce it myself. I'll make a note of it and look into it some more. Thanks for the report.

Fair enough.

In my mind, it would be handy to have each individual device labelled according to the "-d#" flag that gets passed to the miner, in order to troubleshoot problems. However, just to confirm that all devices are mining, a total # would be sufficient.

I have two wishlist items:

#1

On the history tab, the one thing I feel that is missing is a column for how many hashes were accepted during the mining session.

I feel this information would help to identify coins or pools that are not worth mining even if their profitability is high. What I mean by that is that if I'm mining say Megacoin and get 2 or less accepted hashes for a 30 minute mining session, and I get say 40 accepted hashes for say Litecoin or Grandcoin, then that would tell me I need to either find a better pool for the low hash rate coin, or quit mining it and dedicate more time to different coin.

Does this make sense?

Thanks in advance.

#2

Is there any chance you might look at adding pooler-miner to the miner list?

I have several machines that would do well with scrypt mining on CPUs. It would be nice to be able to mine these machines while certain currencies are still young.

Sure I can add accepted shares to both the History tab and the history data (all data is kept in a JSON formatted file with the other MultiMiner settings file in %appdata%).

I won't say "no" but it's doubtful. Right now quite a bit of the code is written around using and supporting cgminer and bfgminer as they have very similar commands and APIs. It really depends on the demand from users, but right now there are not a lot of people trying to CPU mine.

Found a little problem for me, MobileMiner uses OS windows system name to show my rigs.
If i change it, MobileMiner begin to show me both systems, old and new, and old one is always offline. How to remove from list?

Sadly the program crashes constant when i try to use bfgminer

Are you using the Android app or the iOS app? In the iOS app if you swipe the row you can delete individual machines.

This feature isn't in the Android app yet but will be in the next update. If you'd like to let me know the machine name I can remove it manually.

Please post the full error text for any crashes using the .Debug.zip file found on the Github releases page.

I have a question for the Multi-Miners out there... Do you run Multi-Miners off of pools or solo mining primarily? Most of the alt-coin pools are PPLNS, which discourages pool-hopping if I understand it correctly, because there's kind of a buffer period after you start mining before you reach maximum profitability with the pool. So if you're switching a lot, it seems like you can get stuck in that buffer of unprofitability. This is not the case with solo mining, and if you pick coins with a lower difficulty, there will be less variance and the switching won't matter as much, but... Whenever I try to run more than three wallets on my system, they start having trouble syncing individually.

How are others out there running Multi-Miner?

Just wanted to note that I do plan on adding a configurable "minimum time" spent mining a coin. This would prevent strategy switches until a given coin has reached passed that threshold.

Aside from that I'd love to hear what others have to say on the topic as well.

I actually mostly use it for it's crash recovery features. I use one pool, but if my devices become sick, have zero hashrate for a time or the miner crashes, MultiMiner will restart the miner. So handy not to have to monitor it constantly.

I use information from the CoinChoose "LTC Profitability" tab for my mining -- is it possible to use MultiMiner to mine with a strategy based on LTC profitability?

I've got this ready for the next version. The only problem is, as of now, the CoinChoose API doesn't return the adjusted profitabilities when you specify LTC as the base coin. So only the Straight profitability option works.

I sent a PM to the site owner to see if that's something he can add. If/when he does that will start working properly all-around in MultiMiner.

My second wishlist item is not as important. I would like to see the accepted hashes in one of the near future versions. Thank you in advance.

Very odd, it is the other way around for me. I barely can get CGminer to mine SHA256 coins, and it still crashes, BFG v3.1.4 is rock stable, and it will mine SHA256 on my nVidia equipped laptop, where CGminer does not.

Here's a preview of the new Configure Strategies settings in the next update:

• Ability to automatically mine based on difficulty and price (in addition to the current profitability support)
• Ability to specify Litecoin as the base coin used to determine profitability on CoinChoose.com
