Getting a LOT of orphans today :/
You might want to check you're not on a fork or something.  I've not had a single orphan since day 1 (many hundreds of blocks)

Sorry, I don't understand what "chainspermin", "chainsperday", "primespersec" mean and why it isn't proportional ?
What is important among the 3 ?

If I got the essential ones of the last several hundred posts right, the "chainsperday" seems to be the best indicator for the speed of the miner, whereas the other two seem to be not as useful for indicating the mining speed.

Also, in case anyone is curious

24-core Opteron 6164HE 1.7GHz:
"chainspermin" : 29,
    "chainsperday" : 1.67533939,
    "primespersec" : 8389,

32-core Opteron 6274 2.2GHz:
"chainspermin" : 12,
    "chainsperday" : .71721642,
    "primespersec" : 7039,

Because 6164HE is K10 and 6274 is Bulldozer. The 1st consists of two downvolted/downclocked Phenom II X6 dies, therefore 12 FPUs per each CPU. The 2nd consists of two downvolted/downclocked FX dies, therefore 8 FPUs per each CPU. In addition, K10 delivers better performance per GHz, though Bulldozer supports AVX with FMA.

Has anyone mined a block with the same address more than once?  I am community oriented, maybe someone else has an idea or a solution?

I have used keypools=10000 to start a new wallet with 10,000 addresses (which is what I thought keypools would do, similar to bitcoin)

 Any idea why I am receiving a block with the same address more than once during solo mining?

That is typical if you have multiple miners sharing the same wallet. Each miner will randomly pick an address out of 10,000 keypools, and there is destined to be duplicates between miners for picking the same key at some point.

Simple question simple answer. Thank you so much.

Anyone mining with 16core VPS? What OS do you use and how many block can you get in 1day, 1 week?
Thanks very much.

Getting a LOT of orphans today :/

I noticed that if you start a machine where the blockchain is not up to date and where the wallet is more current, transactions show up as orphans until the blockchain is synced.

That happened once yesterday, I had just started a new vps and found a block in 30 seconds that was as you say an orphan. I went from nice surprise to being pissed in a second.
The other orphans were not from fresh install. How do I check if I'm in a fork ? I doubt this is the case as most of the blocks are plain normal.

Well, block payments just dropped below 11 and difficulty passed 9.54

It's amazing how much a software update and better parameters can get you.
On that note, I'm starting to think the chains/day measurement is becoming less accurate.  Either that or I've been quite unlucky.

Hm, maybe the SCAM added not with "ZAX", but with "za*"  Grin

Better not make worker with Z !!! But not with T too. Just with b or r Wink

It seems to not be accurate for me - I haven't gotten any blocks since the 25th (other than an orphan on the 25th) on my desktop though so I feel it's hard to tell.  Then again my sister got three blocks on saturday with the same cpu... It seems like it's a rough average that was accurate when it was added but is slowly becoming less useful for judging how often you might get a block from my experiences.

Don't just trade, get paid to Atomic⚛Trade !!!

I wonder if there's a way to use  stats like jhPrimeminer (ypool client) does but in this build. Basically counts how many chains per hour of different lengths. For instance, my AMD Phenom II X4 is currenlty 17 6-length chains per hour, 193 5 length/hour, and 2046 4-length/hour. There are more stats of course, but that gives you an idea. If you let it run for a day or so, it is quite accurate.

One major misconception on this coin is people think it acts like any other coin out there... in one way it does, but for the most part it doesn't.  Bitcoin, Litecoin, etc, all use a hash.  Since the hash needed is random, it takes time to find.  This is the only area where primecoin is like the others, in that it is a random chance to get the right variable to find a prime.  Where primecoin diverges is that it can never reuse a number already found.  Bitcoin and Namecoin can use the same hash and be 'merged mined', primecoin alone can never be merge mined.

The basis behind blocks is finding Cunningham Chains of length N where N is the difficulty rating.  What does this mean?  The smallest known length 9 chains are:85864769  and
857095381 (1st and 2nd kind).  The proof of work on this coin is such that once a prime chain has been found, it cannot be reused.  So each prime found means the one less prime that can be found.  Look at the records primecoin has found in length 9 chains: 2030793138184474269420052163338592688212588454185304749794006580858788424425799 69*179#-1 is 151 digits long!  In a way, the nice thing on this is that as time goes by and the length of these primes gets up into the 1000+ digit range, difficulty will start coming down as they become harder to find and we'll start finding larger 8 chains and larger 7 chains.

Therefore the metric for finding blocks is ever changing, you can't count on what works today being the best thing to do in 2 weeks time as well.  This is an ever changing coin and people really need to start thinking outside the box.

You are proposing to build a model to predict how many blocks can be found per day. As I understandd that was basicly why Sunny added the chains per day gauge. However Sunny pointed out somewhere that chain/d is not block/day. They are just closely related.
