LOL, quoted for posterity. Old BitcoinExpress with his never knowing what is going on and the telling of porkies.... ah

There is no GPU LTC Miner


A lot of the CH Sock Puppies claim to have seen it, vouch for it but not one can provide a screen shot, video or link. Twenty plus people have downloaded and no one can post it?

As far as Coinhunter, his credibility speaks for itself 

As bad as Coinhunter despises Coblee and Litecoin, if he had a GPU miner that would essentially destroy Litecoin he would release it ASAP. Solidcoin is that desperate to gain status.

Bottom Line: This is a Solidcoin fabricated lie.

Goes to show where the best developers are... working at SolidCoin.

"GPU resistant" . Nice work artforz and coblee, fooled your few fans for some months. Reaper gets 200KH/s on a 5830 . artfoz and coblee went around telling people gpu mining was impossible because they only got 9KH/s on a 6870.... believable with hindsight?

Has anyone been able to confirm the claim? My rigs are in a different continent and I can't install Windows on them right now.

Just about to test it on my fx8150, (gota compile for win64 first)
Any use for the instruction sets that the fx8150 has?

(MMX, SSE 1 2 3 3S 4.1 4.2 4A, amd-v, aes, avx, xop ?

Question:  Is the password really that important when mining from the local client?

No luck so far...

I created the litecoin.conf file and I changed only the rpcuser and rpcpassword values.  Then, I edited one of my .BAT files and tried both my own IP address and http://127.0.0.1:9332/ as the URL, and I switched the user and password values to match the ones in the .conf file.

I tried to open the BAT file to run the miner (with Litecoin-QT open) and it says "HTTP request failed: couldn't connect to host" and "json_rpc_call failed, retry after 30 seconds."

I'm not sure what I'm missing here.  Any ideas?

Edit:  Well, I think I fixed it.  I'm actually not 100% sure how I fixed it.  I think what happened is I was editing some of the files (the .bat, the .conf) but I didn't restart Litecoin-QT after making changes to these files.  When I restarted Litecoin-QT, it allowed me to connect to the host.  Sweet   Let's see if I can repeat the process on my other computer with similar results.

Actually we are against that in principle, but it's hard to stop a bank at the moment if they truly wanted to buy many SolidCoins. I'm sure if they offered $10/coin a lot of people would "cash out". That cost is still significantly higher than a Bitcoin attack. That said being a trusted node doesn't really give that many "Special powers" it just protects the network by limiting the number of blocks non trust nodes can create in a row, making it more fair and less "Suspicious" of miners holding back blocks. If a bank/government became a trust node RIGHT NOW they could cause some annoyances and slow the network a little, but they couldn't stop it.

There will be work done on trust nodes going forward to improve them. SolidCoin aims to protect its users from government, bank and large corporation attacks, so that is where work will be done to ensure that's the case as much as it can be. It's going to be hard. You can read some more about that on our myths page :-

There has yet to be a Bitcoin derivative that has come close to being half the price of a Bitcoin. I just one other peoples' opinions on the matter. I think it could help the crypto-economy if we had multiple currencies once the user base is large enough, but might also hinder it. If people choose one currency over the other this creates competition. Competition could go either way, raising or lowering the value of the coin. I just spent a few Bitcoins on a new CPU cooler to Litecoin mine with, and I've made about $0.80 mining with 30kh/s for a day or two. Maybe this is like Bitcoin, where the price skyrockets after it is publicized, making early adopters and on time sellers rich.

Opinions?

How in the world are you getting 10.5 KH/s per core?

No that's just what an idiot thinks. Either you don't have the brainpower to understand how SolidCoin works or you are deliberately being obtuse to serve some other purpose. If you think 12 million coins that can't be spent is "holding it back" then you shouldn't use any cryptocurrency because it is software and it can be changed! You need to leave the "big time thinking" to the people that can understand it and just have faith. You seem to have faith in Bitcoin for whatever reason, good, stick with it, see how you go.

Thanks for the inputs.
I would be mining for around 14-15 hours per day.
In that case, solo mining is not feasible, pooled mining would be better?

I think you should find out more about why Coblee created litecoin :-

Either litecoin is a CPU coin or the major reason for its existence just disappeared?

From the latest stats it appears GPU mining scrypt is 25-35x faster than CPU, is able to be stacked in the same PC and is 6-10x more efficient.

Check out SolidCoins mining page for info on how a correct implementation of CPU/GPU hard algorithm should figure in performance.
http://wiki.solidcoin.info/wiki/Mining_Hardware_Performance

One thing (somewhat theoretical) I would throw out there is that as GPUs become more "CPU like" they will devote the necessary resources (transistors and chip yield) to increased L1 cache.  GPU long since outstripped the growth in pixel counts so they devoted more resources to improved image quality at a fixed number of pixels and/or polygons.  The GPU resources are growing faster than developers ability to use them as devising more complex and realistic "effects" requires more human capital than simply doubling the polygon count or going from a 800x600 pixel count to 1920x1200 pixel count.  So it will be increases in GPGPU workload which increasingly drives development of future GPUs.   

GPU traditionally had very little local cache because there is no need when performing traditional graphics work.  That dynamic likely won't hold true in the future.  NVidia Tesla cards for example can be configured to double the amount of L1 cache because it is so useful in boosting performance of some GPGPU functionality.   Larger L1 caches will eventually trickle down into consumer grade products to.

No coin today is "anti-GPU" it is they can be described as "large L1 cache dependent".   Even if GPU mining is impossible w/ todays hardware the desire for GPGPU performance will drive higher cache in the SP for future GPU and eventually they will be able to perform with no limitation.

One "hard" alternative is to make the lookup tables so large they can only fit in main memory (say a 3.2GB lookup table).   That obviously makes the code less functional on those with limited system resources but given CPU access to memory is always lower latency that GPUs it becomes hard to defeat.  Eventually GPUs shared memory will be 4GB, 8GB, 16GB etc so possibly some algorithm which adjusts size of lookup table based on Moore's law might be needed (i.e. uses a 3.2GB lookup table at current block but that increases by 7% every 40,000 blocks as part of the protocol, maybe on a multiple of difficulty like every 8th difficulty adjustment is also a memory adjustment).

The first feedback and actually a patch for the Cell miner sent to me as a private message: https://github.com/shakt1/cpuminer
But one problem is that shakti is a newly registered user and has no permissions to post anything here yet.

edit: here is his thread in the Newbies section: https://bitcointalk.org/index.php?topic=64222.msg753270#msg753270
If there are more people "on probation" (maybe newcomers from the playstation3 linux community), then it could be a good place for them to post some comments.
