Make sure all blocks is updated in your wallet,.

you should update wallet too, I got that error yesterday. After updating wallet, problem is solved.

Sorry if I missed this but all I get running the miner is "failed to update height".  I see there is an updated miner coming shortly so will wait for that, but thought I would try again as there was an update since I last tried.  Before it just crashed after a few minutes, now only this error.

The Wallet needs to be running when you run the miner. Also you need to get both the updated wallet and miner not just one of the updated pieces.


Yeah I downloaded the latest walletn redownloaded the blockchain and used the newer miner.  Downloaded both from Vic's latest post where he linked them.


As I stated, I did in fact update both the wallet and miner from Vic's last post.  In checking the wallet again, I am running the wallet dated 9-26.

Just checked and tested everything again.  I am definitely running the wallet and miner dated 9-26.  My wallet shows synced and getmininginfo shows I am on block 4262.  Ran miner again, still same error "failed to update height".

Got the miner enhancements. Kids are up at daybreak, so I'm off to bed. I'll get to this first thing in the morning. I'm also working on the two issues: segmentation fault and failed to update height.

Keep posted.

All good man, thanks for the update.

Still have not been able to earn any coin, looking forward to seeing a non zero balance in this long awaited project:-) 

I just noticed I have been referring to you as "Vic" and not "Viz"........apologies for that!

Something is up...

I started mining this about 24 hours ago. In the first 12 hours I managed to find 30 blocks with 14 high end cpus. After updating to the latest wallet and 64bit miner I have found 0 blocks in these last 12 hours. The difficulty has remained the same around 4 the whole time.

Has anyone found any blocks since updating their wallets and miners?

Have you worked out the block rate?  Maybe someone has a significantly enhanced miner and is just getting all of the blocks before you... 

On a totally different and not in any way related note, I stopped mining around 36 hours ago, around the time that SuperComputer started working on improving the miner.  I noticed from his debug output screenshots that he was mining consecutive blocks.  Not sure whether it was on the test net or not though.  I'll start mining again when Viz releases the new miner with SuperComputer's update (or has that already happened?Huh)

I get a block per day with the Windows x64 miner, maybe it's just luck?

I have a Core i7 3930k and I'm only using 4 threads.

How many PPS do you have with that i7?

Everyone,

I checked through Supercomputing's code, currently his optimization is only for difficulty 4.x which will not be sustainable for long, especially when it is released [Difficulty will go over 5x]. I've been seeing difficulty climbing up to 4.9. Each 0.1 increase in difficulty is a 5x increase in time required to find. This is why no blocks have been seen by small miners, I haven't seen one for a day or so.

I am testing a fix for the segmentation faults, and made some optimizations myself. I've been running that for the past 12 hours on testnet and it seems to be stable, so I'll get to cleaning up this code and upload new binaries and GitHub. PPS increase from 40 to 55 PPS.

I'll release an optimized miner with Supercomputing's updates once I verify his code's full functionality. I'll be working on getting his optimizations working for all difficulty sizes, sent him an e-mail about the same. I have to understand his code and verify its functionality before I release it.

I'll keep you guys posted,
Viz.

With 4 threads I get about 70 pps. With 12 threads I get 120 pps but the miner constantly restarts. I can leave it on 4 overnight without it blue screening Wink

I just checked my pc that has the wallet, looks like I found 4 more blocks since I posted. The CPUs I'm using are o/c'ed i7-4770K's.

Guess its just more people hopping on the network and I had bad luck last night. I also restarted the wallet after I posted. That could have had something to do with it.

I asked for comparison, I get around 70 pps with 7 threads with fx8350 and no blocks in last 24hrs with 2 of them.

@Videlicet

The source code contains an implementation of wheel factorization:
http://en.wikipedia.org/wiki/Wheel_factorization

Primorial = size of the wheel:
http://en.wikipedia.org/wiki/Primorial

PrimeLimit = factor base:
http://en.wikipedia.org/wiki/Factor_base

BitArray_Size = size of the bit array:
http://en.wikipedia.org/wiki/Bit_array



Then we apply the above method to search for prime quadruplets:
http://en.wikipedia.org/wiki/Prime_quadruplet

Prime constellation of various lengths have different forms:
{30n + 11, 30n + 13, 30n + 17, 30n + 19} for prime quadruplets.
{30n + 7, 30n + 11, 30n + 13, 30n + 17, 30n + 19, 30n + 23} for prime sextuplets.

From WikipediaA: "A prime sextuplet contains two close pairs of twin primes, a prime quadruplet, four overlapping prime triplets, and two overlapping prime quintuplets."

So uncommenting portions of the source code should sustain a difficulty of 6.x for a while before we optimize for prime octuplets.

Supercomputing,

I understand now - Thank You - this is a great idea. The problem I see though, is that you are searching for each cluster with a defined set of gaps instead of ambiguous set up to +12 for the prime gap. This miner will be useless when it breaks difficulty 5x and it won't find all specific prime clusters that are possible, just a defined set. It needs to be able to find at least 2.x, 3.x, 4.x, 5.x if you are to go this route, the difficulty is already getting very close to 5.x.

I developed this algorithm with the thought in mind to find constellations of any size. When they get very large they can be gapped as such:
+ 0, 6, 8, 12, 18, 20, 26, 32, 36, 38, 42, 48, 50, 56, 60, 62, 66.
+ 0, 2, 6, 12, 14, 20, 24, 26, 30, 36, 42, 44, 50, 54, 56, 60

This is not deterministic for the constellation of size X, for they follow random patterns. Sometimes +2, 6 other times +2, 4.

From a paper of constellation records, the largest gap I saw was +12 in very large constellations. This is what this is based from. Once your miner supports more difficulty sizes I will implement the update in my Github. Otherwise you are free to use / give your miner away, host your own github, etc.

If this is the case, let me know and we'll be sure to update the OP with links to your experimental optimized miner.

@Videlicet

You are missing one important fact which is smaller prime constellations are always embedded within larger prime constellations. So the code already finds constellations of all sizes but we are only interested in those which meet the minimum difficulty requirements. If you cannot follow this logic then it would be best if I host the code. Sometimes, seeing is believing.

This is really making less and less sense!  With a coin requiring specialized mining, it should NEVER have been released without a better tested and vetted miner!  You have essentially had a single person who understands how to code and has ENORMOUS CPU power acquiring most of the coins the past few days while most everyone else has not been able to earn much at all.  I have not been able to mine more than 10 minutes without crashing and have been able to earn ZERO coins.

Fair distribution is very missing here and it gets worse with each passing day that this one person can mine the vast majority of the coins!!  Personally I think the only fair thing to do is to pause this project until a fully functioning miner can be given to EVERYBODY.......this should be relaunched at that point!
