Sorry guys, took my code down for a variety of reasons but I am considering re-posting it.


Yeah, its a fine solution in this spot.  Check out the Diablo miner if you don't believe it.  Java 4-ever http://www.youtube.com/watch?v=vL1riGEwkFo

If you think the C# scene is being underrepresented here, why don't you create your own C# miner?

Would you see this replacing a stale work timeout?

I sent out messages to the people who have volunteered.  Please let me know if you have any trouble getting to the binary or source and if you have any questions.

Thanks again for your help.

Ive posted my code on github:

https://github.com/johncarl81/MeteorMiner

I will post the binary artifact soon, possibly on sourceforge to distribute for the beta.

If you feel adventurous and want to build from source, go right ahead.  Please PM me with questions / issues.

Yes, performance is decent.  There already is a java Miner out there called Diablo if you want to see for yourself.

Even the fastest CPU miners would not hold a candle to a gpu miner, and are arguably a waste of energy, so the one I am including is just a proof of concept.

Great input guys, Im really encouraged by these suggestions.

Honestly, my inital beta will not include a majority of these suggestions, but I certainly want to put some of them into future stages.. and possibly leverage you guys to help.


Props for identifying that malicious code and outing that guy


Really good idea... I think I may be able to add that for the beta.

Just read this post:

http://forum.bitcoin.org/index.php?topic=11723.0

I will be providing my code along with the beta, in case anyone would like to inspect for shenanigans :-).  This is one reason I gravitate towards open source.

Im pretty sure temperature and fan output would be very hard to make portable across gpu / os.  I think we're going to have to use a separate monitor for those.

Thanks for the input, ill add you to the beta.

Thats not a bad idea too and may go hand in hand with Tycho's suggestion.  I'll see about adding that too.

That should be pretty easy to add... I'll get on that immediately.  Is this a new feature for deepbit and do the other pools implement this protocol?

Quick update:

Just about ready for this beta with some good results on my end.  I will probably be contacting people that responded in the coming days to set up some trials.

Here are the features I have included so far:

gpu and cpu mining
multiple gpu support
long poll
multiple theads per gpu
various timeout parameters: getwork timeout, error timeout
tandem mining.

There is also no perceived performance difference when mining in tandem vs mining in parallel... at least with my 1 gpu and multiple cpu miners

Ive also put some work into unit / integration testing and archetecting the application, which I think has some merit.

All that being said, I would say my mining speed is comparable with all the other top miners.

Also, I have not focused on some of the more gpu / kernel specific compilation parameters (LOOPS, BFI_INT, etc), but im sure those will be easy to add.

Again, if you're interested in beta testing, contact me.

Agreed, a GUI would be nice.. I wonder if I could throw one on.  I know that there is a python based miner with a GUI out there.. haven't tried it though.

I wonder if I could handle the data differently than a crossfire/sli would... certainly at a higher level and simply divide the work chunks (what a gpu mines at a time) between the cards.  Potentially the overhead would be much less than fully integrating the cards together.  Unfortunately I don't have multiple GPUs, so im a little handycap writing this sort of code.  I think I may try it, as an option, but I think the default will simply give each card their own work.


I'm writing a Java based miner.  Target platforms are Linux and Windows... Ive heard Mac/OSX doesn't support opencl very well, but I guess it's a target as well.  I use basically the same opencl kernel that poclbm, phoenix and Diablo use.


Python makes my brain hurt too ;-)

Glad to see some responses to my post.. thought no one was interested ;-)  I'm planning on posting my code on github.. you guys interested in beta testing?

Ive been working on a miner and I have some questions around what people would like to see.

Would multiple cards working in tandem be attractive?  As in, multiple cards working on the same work request.  I am not sure if this would prove to be a faster way to mine, but it is an alternative to running separate miners on separate work requests per gpu.  In addition to this, I have the option of running 1 miner to handle multiple gpus in parallel.

I'm also looking to get some beta testers involved in my miner.  I'm not quite ready for a beta yet, but please ping me if you're interested.

Are there any features that are lacking in the current offering of mining software?
