[XPM] [ANN] Primecoin High Performance | HP14 released!

[gwedo]

I plan to download and start mining this next week. 

Primecoin is the third cryptocoin which is exchangable for fiat money (USD https://crypto-trade.com/trade/xpm_usd ).
XPM should cost more. maybe 0.01 BTC.

I have XPM client mining on 9 Win7 PCs. Is there a way to:
1, have it start mining on boot up without having open it, pulldown help, click console tab, type in setgenerate true -1 every time???
2, have other 8 PCs send their coins to my main workstation PC automatically???
TIA, Aurum

ad 1) you can create a "primecoin.conf" file at %appdata%\primecoin
with

Code:

gen=1

in it. I don't remember whether you need

Code:

rpcuser=yourChosenUserName
rpcpassword=someRandomPassword

as well in that config file. If it doesn't work, simply put it in.
For starting the primecoin-qt.exe you might chose the autostart or the task scheduler - whatever you prefer. With autostart you have at least to log on to the machine...

ad 2) the easiest way would be to share a wallet on those machines. It might be a good idea to create a new one with

Code:

keypool=1000

in the config file. You should backup your wallet.dat on that machine first and move it out of the %appdata%\primecoin folder before starting the primecoin-qt.exe
If you don't create a higher number of keys than 100 (which is default) you encounter the risk that the wallets on the machine will get out of sync once the keys are used up.
I don't know a way to automate exporting and importing the keys on windows machines automatically.
To verify the successful creation you can inspect the results via console "getinfo".

at the moment the generated amount of primecoin is so much, I agree that it's not really cheap to mine xpm , but i guess such prices won't happen until the difficulty reaches something more meaningful, like 12-13 or something. by that time i expect it to be as expensive as 0.01, unfortunately by the current pace of development in mining the coin, i doubt that it'd happen that soon, probably not before a proper FPGA implementation even if such scenario would happen , there would be so many coins in the market that it would not be possible to raise the prices that high .
by then probably another coin will rise with the same algo which can use the fpga/asic, though i guess it's unlikely.
but being a cpu only coin is not good for the whole i believe.

I have no idea how one shares a wallet across multiple PCs. I thought you need the client installed on each PC that is mining. Can you explain more about to do this?
Thx, Aurum

it's simple, just copy the same wallet.dat on all the machines, note the keypool though .
if anyone finds a share, it'll be in the shared wallet and you'll see it in the management node .

Since I've had 8 PCs mining for a week several have coins in them. It takes a long time for them to mature, but I guess I could send them to my broker and then pick a wallet.dat file and copy it around.

Am I supposed to put "keypool=1000" on every PC or just the master? Will all clients share the same 1,000 keys???

Thanks much for your help! This is not intuitive at all.

[manawenuz]

backup your wallet on one of the pcs , remove the wallet add the keypool directive , it'll create new wallet .
import all your immature coins to the new wallet , and replace it on all your pcs , that would do the trick i believe.

The "keypool=1000" does only work when creating a new wallet.dat file as far as I remember. Creation of a wallet.dat is only done when no wallet.dat is found at "%appdata%\primecoin" (just open a windows explorer and copy %appdata%\primecoin into the address bar) so you need to backup your wallet.dat and remove it. Create a backup of all other wallet.dat files on the other machines as well. And create a backup of the newly created wallet.dat. After having created that consider that the master file which needs to be copied to all other machines. With that same wallet.dat on all the machines, they share the same keys. If you think 1000 is too low, make it more

And always create backups, backups, backups.

If you don't want to pay transfer fee for sending the matured Primecoins around, you can export the keys from the existing wallets and import them to the new wallet. This should work for not matured blocks as well (have a look at "dumpprivkey <primecoinaddress>" and "importprivkey <primecoinprivkey> [label] [rescan=true]"). I recommend taking some time for getting familiar with the API. Some explanations can be found in the corresponding Bitcoin API overview. But as Primecoin has some feature Bitcoin doesn't, you might enter "help" in the debug window of the primecoin-qt as well

Some last words.
Sorry that this is not intuitive at all, but you need to gather some info if you don't want to mess your coins up. You need to know where the wallet.dat is, because you need backup of that file. If this file is gone, all your primecoins (private keys) that are "stored" in that wallet are gone. You should consider encrypting the wallet to prevent unauthorized access. If you encrypt the wallet, read the instruction. Create a new backup

That's actually where it was it when I started mining last month. Unfortunately, it's since tanked.

That's not accurate, you can run keypool=xxxx against an existing wallet to increase the number of keys. Then encrypt the wallet immediately before copying it to your miners.  Each miner will then take a key from the pool when it mines a block, so in theory each miner can mine 1000 blocks each before running out of keys.  When that happens, the pool will be refreshed with new keys and the miners will be mining blocks that dont show up in your local wallet.  But if you're mining 1000 blocks per machine any time soon, you're doing something that the rest of us aren't

1.90 chains/day its normal for core i5 2500k (4.6Ghz, hp-11) ?

That looks about normal !

[nhminer]

I have 6 machines running hp-11 x64 Win7;  My .conf file contains very few settings:
rpcuser=solo
rpcpassword=x
rpcport=9912
port=9911
daemon=1
server=1
gen=1
listen=1
maxconnections=100
seednode=primeseed.muuttuja.org
addnode=107.20.202.112
addnode=54.225.123.87
(plus a few more add nodes)

So, here is the problem.  2 of the machines (intel Q6600 and FX; both with 8GB) shutdown every few days without notice
This started happening after hp-8.

Has anyone else experienced this, or just something odd about these 2 machines?

Don't know if this is related but I have a win7 laptop that shuts down at night once in a while with the ypool miner. From the system event log it appears that the laptop just weny to sleep.  In power management I had set it so that it should never sleep. It's strange.

This has nothing to do with your primecoin.conf but is more likely a problem related to the computer itself i'm sure !

Keep an eye on your cpu core temps. Your fan may need a cleaning.

Your systems are unstable and/or trying their last resort to protect themselves from thermal damage.

[ivanlabrie]

Can anyone help with compiling the hp11 miner in ubuntu? I compiled it with the optimizations listed in mikaelh's guide and am only getting 1 CPD, which seems rather low for an FX 8320 octocore...
Thoughts?

Good suggestions, thank you everyone

Clearly -- the interesting thing is that it only happens under the stress of running the primecoin miner
