Primecoin GPU miner: 9.1 CPD on a 280x / pool / 2% dev.fee

[andy_gpu]

Hi, all.

I'm a PrimeGPU team member also.

So I have a couple questions/problems.

1) Running the client on the system with my PrimeCoin wallet, I can't run the client and wallet at the same time -- the wallet is locked out by the client, or vice versa. How do I see my wallet balance? (I guess I just need to run it on another PC maybe?)

It's a known issue. Not sure that we can fix it fast, but we can make a workaround: show the balance in the client.

Practically we can fix it quite soon. The intended behavior is the same as exists in bitcoind/primecoind where you could operate using standard bitcoin's options and commands.
Such functionality exists in our client but does not work because of a code bug. So we should just fix it.
However it will not be possible to start the GUI wallet because it requires exclusive lock to the database.

A good side is that it will be possible to add simple automation of these command-line operations and the syntax will be the same as in existing crypto-coins.

Confirmed.

I can test on 290x cards

[ivanlabrie]

It only works with r9 280x cards for now apparently.

Well, it should work with other "new" cards (7xxx and R9) as well.
But it's optimized for 7970/280x and would under-perform on other cards.

I tried better CPU but then licence is no longer valid..

[jjiimm_64]

I would like to test this.. I have many 7970s and 280x's

[rozey514]

i want to try
16 x r9 280x
best regards

Sent you a PM primeGPU

but I would like to publicly say I would like to help test this GPU miner for Primecoin, I have 7970, 7950 and a few other older cards.

I am the operator of the Official Primecoin Forum (and Peercoin)

happy to help show the community your miner does what it says it can.

PM sent.
Please keep in mind that the miner would probably crash if a pre-7xxx card is installed in the rig.

Found 4 blocks in 24h using 3 and then 4 280x cards with a weak processor. Good stuff.

@primeGPU,

I would like to help test and promote your software, I've sent you a PM.

Thanks

[neza777]

i'd like to test you miner to i have 35 x r9 280x
i'll be glad to test it

Nice I was wanting a gpu miner last year!!!   Glad to see somebody finally pulled through pm sent.

So here are our reasonings regarding licenses:

We do want to get some money from selling the miner. At the same time we don't want to ruin the coin by making it non-profitable via raising the difficulty into 11-chains in a week. We are now looking for a solution that will suit both us and the our customers.

Unless you talk us out of this idea, we are going to sell a limited number of licenses for the first 1-3 months.
The number should be 1440 GPUs - we are able to produce licenses for any number of GPUs (1-6).
This way the number of chains per minute on the network would rise by 1.2 and the difficulty would rise by 35-40%.
2nd month - for 2880 GPUs, maybe 2x this amount. We go open source in 6 months.

Of course, we can't totally control the difficulty:
For example, if a more profitable GPU miner appears and we are unable to optimize ours anymore - we will go open source. This would probably pump the difficulty.

One more thing:
We've already recieved 4 suggestions to sell licenses for farms with 40-60 rigs. Selling these licences would mean that all of 1440 go to 3-4 people/organizations.
It would be very bad for the coin. So our idea is to limit 2 licences (8 GPUs max) per each buyer - at least for first 2 months. We would only sell the miner to bitcointalk'ers with a registration date prior to 25.03.2014.
If we are unable to sell this limited number of licenses within 2 weeks, we would sell the rest to farmers (alternatively - slash the price).

You comments / ideas are very welcome.
Also regarding the price - we would like to hear the voice of the community .

I'd like to see developers getting rewarded so that there is incentives for people to improve Primecoin miners. Someone will try and probably succeed in a month to reverse engineer your miner. I suggest you keep your miner and mine for a while, and at the same time make the miner working for a broader selection of GPUs, so that  you get financially compensated and more people will benefit from it once it is released. However since your miner is already out, that may not be an option any more. Another possibility is working to get developer;s fee from e.g. ypool.

+1 on this!  I don't have much but would be willing to make some sort of contribution myself!

Problem with releasing with dev fee, which is usually the method i prefer to see is the difficulty will climb very fast to the point where its no longer profitable to use the miner, meanwhile the price will tank due to dump fest. +1 to the dev's for trying to take a very responsible course on releasing this I hope the software protection holds out, its in no ones interest to see the difficulty go any higher while the price continues to drop. As to the license fee i hope its not so high that smaller miners cannot afford entry to the market leaving only whales to benefit. Will the price be on a per card basis? Using my rig as an example 4x 280x + E3 1230v3 would 50xpm per gpu be a suitable price, would be nice to have a ballpark figure that you are considering.

[ivanlabrie]

Tried my other system with an intel g465 celeron and 2 r9 280x xfx cards...1000/1500mhz clocks, 2gb 1600mhz cl9-9-9-24-2t ram.
Results:

-Time: 310-350

Using cpuusage=2 for now.

Still not sure if I'm doing everything 100% right.

Here's my primecoin conf contents:

server=1
rpcport=9911
rpcuser=*
rpcpassword=*

Is that ok?

[usahero]

-cpuusage 3 works much more stable on my rig than -cpuusage 2. With -cpuusage 2 time is higher and not very stable, as it jumps from 290-350. So I am running 4 cards @ 1125 Mhz, 65'C, and Time is stable around 280s. With better cpu that Time would probably be around 220. Already found 7 blocks which is very impressive.
