[XPM] [ANN] Primecoin Release - First Scientific Computing Cryptocurrency

[Moebius327]

Interesting that some optimized primecoind builds are being shared now, but the block spacing has gone from ~10 seconds back to a more reasonable ~30 seconds.

From this we could conclude either:

• these optimized primecoind builds are worse at finding blocks despite higher primespersec
• or, a superior stand-alone miner was tested on the network and is currently offline pending release...

there you go. the answer to your questions

There is currently a DDOS against http://Digitalocean.com  we have updated our status page: https://status.digitalocean.com  & https://www.digitaloceanstatus.com

I don't think this is related as it is unlikely that efficient mining in the hosted instances was the cause of the ~10 second block spacing we saw earlier, and Digital Ocean's status states that customer's virtual private servers are not affected by the attack. If just 1 VPS was targeted by a DDOS then the operator would stand up another VPS pretty quickly.

Doing pretty good on my own optimized x64 build of primecoin...

Anyone know how to import a priv key?

I tried :

importprivkey <<Privkey>>


But i got an error message.
i know the key is valid.



EDIT : i found how to do
You need to unlock your wallet first with

walletpassphrase "YourwalletPassphrase" 600
The 600 means your wallet is unlocked for 10 minutes (600 seconds).

I'm getting 0 primes per sec even though the CPU usage is near 100%. I'm running Ubuntu 12.

All I did was
1. Set rpc user and password in .conf file.
2. run "./primecoind -daemon"
3. run "./primecoind -setgenerate true 8"

Then when I run "./primecoind getmininginfo", it says my primespersec is 0 even though CPU is being used.

Can someone help me?

Okay, can we get instruction on how to extract coin from our DigitalOcean droplet.  It has been so long since I have had to do console/coding like this .

Sure. I do it this way:

• ssh into remote instance
• ./primecoind listtransactions –> copy the address mentioned in the output at "address"
• ./primecoind dumpprivkey {{paste copied address here}} –> copy the private key returned
• on your local computer holding the "master wallet" -> ./primecoind importprivkey {{paste copied private key here}}
• now address holding the minted coins appears in your local wallet

No need to send coins over the blockchain this way, immature coins can be imported immediately.

I understand you will get the minted (even immature) coins from the remote wallet, but since you dumped the private key remotely, will you be able to get any new coin?

And will a new private key/public key generated in the remote wallet?

I am close to closing down here giving up on this coin. 14 hours I have been mining on all 4 cores of a 2500k and a 8 core ec2 instance. Not one block yet.

Are people getting blocks still or are there a load of optimized clients gobbling up all the coins?

[craslovell]

110K coins minted, I wonder how evenly spread it actually is. Somebody must be baggin'

I'm running 6 different CPUs and have about 160 XPM so far

I think all the optimized people are sucking the blocks up. I haven't gotten one in about the same amount of time with 6 different CPUs

Hey Midas, err I mean Sunny King ;o) Nice job on the coin. Lots of good publicity right off the bat also.

and whomever take offense at this or not... Are you really complaining about someone not releasing an optimized miner because it's somehow not fair that they used their education, intellect, or a combination of the two to adjust how the client runs? By the way, is that an obama phone I see in your pocket?

People will bitch about anything bro!!!

Either way here goes again!  been mining since a couple hours after launch on my 3770k @ 4.37 on air

I left this on overnight a got three blocks late morning, all within three hours of each other.

12 hours later and I've had nothing since.

Intel i5

{
"blocks" : 5742,
"currentblocksize" : 1000,
"currentblocktx" : 0,
"errors" : "",
"generate" : true,
"genproclimit" : 2,
"primespersec" : 80,
"pooledtx" : 0,
"testnet" : false
}

I mined 160 on 1 CPU since the genesis of the coin.

Compile with gcc 4.6.x+ x64 and these compilation flags:

Code:

-O3 -march=corei7-avx -mtune=corei7-avx

My rates haven't changed much over ~36hrs, but I still see no clear relationship between no. of cores/speed of cores/core:memory ratio and rate of finding blocks

I'm still getting blocks, well on my i5 laptop anyways. I have 2 amd machines that haven't done a thing as of yet. I have 6 blocks on the laptop, last one was about 2 hours ago. Just stock client as of now.

[poiuytr4]

The client is using some sort of sieve to mine for primes. Is this so that you can check for chains starting at multiples of the origin using the same sieve?
When you hash to produce your origin why not just check for the chains using the verification tests ie the Fermat and Euler-Lagrange-Lifchitz tests? If the chain length is only seven then you would only have to perform the tests eight times for each origin or multiple of origin.
 Then you could double the origin and use the verification tests again or you could hash again for a different origin and use the verification tests again.
 Would this just simply be a slower method?
 Or have I misunderstood something?

Close to what i have been experimenting with, need to reinstall ubuntu first for the 64 part. Just noticed i have been sloppy earlier

Thanks

Ok!!... I think I got it... I think I have to sacrifice a virgin in a pyre meanwhile I performance a tribal dance in order to get more blocks... ok... so... I'll tell you the results in a while (when I can find a f***ing virgin... of course) 

No joke, I had 12 servers on this (8 AMD phenom x4 965s and 4 Xeon 5xxx series...12 cores each) and didn't find a single frigging block.
