Is there any way to make the gpu miner use any other gpu besides gpu 0?

edit: found the answer to my question

why involves only one GPU

You have to use one instance per gpu.
Use --gpu-dev <id>, to select the right one.

That means you are connecting with the wrong protocol. Are you using the stratum port or rpc port?

I made a thread here twice https://cryptsy.freshdesk.com/support/discussions/forums/4000000207 but it never showed up. Dont know why.

Someone else may want to try it again. Or just spam cryptsy. They add every shit coin that exist i dont think they will have a problem adding gapcoin...

I'm confused by what a gap and a merit is

You have two following prime numbers like pn=11 and pn+1=13. The gap is gn=13-11=2.

The ratio of gn / ln(pn) is called the merit of the gap gn.


Now why and if bigger merit is important i dont know.

Now why and if bigger merit is important i dont know.

The average size of a prime gap increases with higher primes and is about ln(pn).
In fact it its very trivial to find a gap with at least length n:

Quote from: Wikipedia
For any prime number P, we write P# for P primorial, that is, the product of all prime numbers up to and including P. If Q is the prime number following P, then the sequence

P#+2, P#+3,...,P#+(Q-1)

is a sequence of Q − 2 consecutive composite integers, so here there is a prime gap of at least length Q − 1. Therefore, there exist gaps between primes which are arbitrarily large, i.e., for any prime number P, there is an integer n with gn ≥ P

The merit is the ratio of the size of a prime gap in comparison to the average size of a prime gap in the proximity of p.
To find a gap with at least merit m, the average calculation amount is e^m primes.

To sum it up it is easy to find long prime gaps, but it is very difficult to find prime gaps with a high merit.

I just wrote cryptsy, and they "submitted the coin to their development team who will review it to see if it meets the requirements for addition to the Cryptsy exchange."

Got the same but nothing happened after days passing. In fact if i go now and try it again because of the title it finds the post i tried to make in the 'Matching Topics Found' with those links but they just doesnt show up:

It's the shame that coin with such beautiful idea for PoW is semi-dead now.  Embarrassed No way we can set a record with such volume and price. Well, RIC also not very active, but I think prime gape searching is more simple and elegant idea, also more clear for 'average man'. Looks like only good old Primecoin is more or less alive in 'prime family'.

Hi there,

I just want to inform you that Gapcoin just broke 544 records of first known occurrence prime gaps.

The records are listed here:

http://www.trnicely.net/gaps/g4k.html
http://www.trnicely.net/gaps/g6k.html

Even if we are currently a few of steps away from the world record of the highest merit primegap,
I'm pretty sure Gapcoin can break some more records on those lists.


All gaps found by the Gapcoin network can be download either as plaintext or zip from the website (http://gapcoin.org/downloads.php).
The files are updated every hour.

I'm currently working on a method (involving Chinese remainder theorem) to improve the mining algorithm.
(I'm not really sure if it can be applied to Gapcoin's mining algorithm, but I'll keep trying)

I'll also working on a tool for parsing and processing Gapcoins prime gaps.

(both will be released here, when finished)

I already wrote them, once we got listed within the top-20,
but I submitted the new records too.

I don't think it's dead, I don't think anyone has ever heard of it, yet. I found out about it on accident. I think a tiny bit of promotion would bring many people in.

The coin's early inflation is what was driving the price down, the total coins was doubling every few days, then weeks, I think now it is probably 50 days until it doubles again. But market cap has stayed around $5000 the whole time.

No one is dumping (I'd buy if they were), and only 30% of all coins are on poloniex. Who's hoarding the rest?

And to top it off the hashrate has not dropped much, it is around the same it was a month ago, it did not crash even though the price did.

So I am still very optimistic on this coin. Overtake Donald Knuth's record and you've got a great news story that can make it to programmer circles and gain new interest.

need some updates:
1. wallet
2. site
for a start it will be enough.

crz just sent me the new logos for the wallet,
unfortunately I don't have access to my compiler environment over the holidays,
but I'll publish the next wallet release afterwards.

I just made a few updates to the website, including the prime gap section.
The is a new site containing new first known occurrence prime gaps which are not yet listed at http://www.trnicely.net
I'll frequently submit the gaps listed there, so please don't spam Dr. Nicely.

http://gapcoin.org/primegaps-length.php

ps: I submitted the gaps only two days ago, and we already found 29 new records.
