Trying the new miner and generating a new crt file. Can you post an example command to mine after the ctr file is generated? Do we still use sieveprimes? Is ctrevolution used in the ctr generation and the mining command?
ctrevolution and ctrprimes are only necessary for generating the ctr file. sieveprimes will still be used for mining. Mining still works the same way as in the previous ctrminer version: ./gapminercpu localhost p 31397 u <rpcuser> x <rpcpassword> shift 1024 crt myctrfile.txt threads 4 fermatthreads 1

nscythe, same one that has all the cpu power? If you're still mining on shift 25 you may mine faster on the higher shifts (400600). It's still solo mining but the second release of the chinese remainder theorem, this latest release let's you build custom crt files.

CTR GapMiner UpdateNew Feature: Creating custom ctr filesThe ctr algorithm is divided into 2 parts. The first part, is a simple greedy algorithm which ties to find offsets for each involved prime, so that the desired number range has at least prime candidates as possible. The second part is an evolutionary algorithm, which tries to improve the results form the greedy algorithm. Therefor the greedy algorithm will be executed several times with slightly different parameters, to produce ctrs which differs in quality, which than can be used by the evolutionary algorithm. The output is a text file which can be used by gapminer as an input for ctr sieving. Parameter description: calcctr Indicates that we want to calculate a ctr file.
ctrstrength This is used to variate the computing time spend within the greedy algorithm. Higher strength can yield better results.
ctrprimes The number of primes to use in the ctr file. The more primes the better the ctr result, but the shift also increases. Minimum shift can be calculated as the binary logarithm of the product of all primes: log2(p1 * p2 * ... *pn).
ctrevolution Whether to use the evolutionary algorithm or not.
ctrfixed This number indicates the number of starting primes which wound get touched by the evolutionary algorithm the offsets for the primes 2,3,5,7,11... are mostly perfect computed by the greedy algorithm, and changing them only declines the result.
ctrivs The number of individuals used in the evolutionary algorithm. More increases computing time but mostly also the result quality.
ctrrange Percent deviation from the number of primes. Useful if you don't want to look for a specific number of primes.
ctrbits The shift value you later use for sieving has to be greater than log2(p1*p2*..*pn). With this flag you can fine tune a specific shift by setting this to shift  log2(p1*p2*..*pn).
ctrmerit The target merit (while testing the ctr it seamed that sieving for targetmerit  1 yields the best results)
ctrfile The target ctr output file. You can open this with a text editor. Look for the n_candidates value, the smaller it is the better the ctr file.

At the ctrbits flag you have to subtract 256 from the given value. The links above were updated. Any already generated ctr files can still be used, but they are targeting a 0.25 (130 primes) till 4.7 (14 primes) times greater merit.

I was wondering why a shift 1024 was taking multiple days and counting though I had set the ivs to 10000 and the target shift to 20.

I'm not sure the table for ctrbits is fixed.
Example: If you want to generate a file for shift 384
ctrprimes = 58
ctrbits = shift  log2(p1*p2*..*pn)  256 ... ctrbits = 384  log2(58#)  256 ... ctrbits = 384 64  256 = 64
Yet the table shows the ctrbits set to 16 for primes=58.

It's: ctrbits = shift  log2(p1*p2*..*pn) ... ctrbits = 384  log2(58#) ... ctrbits = 384  368 = 16 The ctrbits in the original file were 256 bits to high.

Good work with the latest CTR GapMiner (CPU) Initial results for: Sandy BridgeE  Intel Core i7 3930K CPU @ 3.20 GHz (Factory Overclocked to 4.1 GHz on all cores) with liquid cooling. 6 Cores and 12 Threads. Just running with 6 threads atm. shift 896 crt crt/crt22m896s.txt threads 6 fermatthreads 1 sieveprimes 500000Seems to be the most 'optimal' / highest pps shift out of the full range I tested.pps: 2100000 / (lowest)pps: 3500000 / (avg. approx.)pps: 5100000 / (high)Have yet to test with full optimizations etc., Noticed that shift multiples of 64 always seemed to yield a higher pps average on 64bit over shift multiples of 32 ? EDIT: 'tested' optimizations: shift 512 crt crt/crt22m512s.txt threads 8 fermatthreads 7 sieveprimes 10000 pps: 15,000,000 (avg. approx.)

Submitted a coin voting request at cryptopia exchange: https://www.cryptopia.co.nz/Home/Voting for Gapcoin. EDIT: It is now possible to vote for Gapcoin. N.B. Listing is currently "Awaiting moderator review..." So, we can't vote for Gapcoin just yet.... Perhaps we could try to generate some additional relevant interest in Gapcoin via the official twitter: https://twitter.com/GapcoinHow about following some University "Department of Mathematics" etc., as well as their followers ? Cheers!

Gapcoin is better than most shitcoins and the cap is just 11 BTC. The coin does useful work, has no pre/instamine, has an active dev, etc. Fuck it. This is ridiculous. What's wrong with this world? This one is extremely undervalued. Buy while you can.

No. Not at present. You can try solo mining though. gapcoin.conf listen=1 server=1 rpcuser=<rpcuser> rpcpassword=<rpcpassword> rpcallowip=127.0.0.1 rpcport=31397

Market cap only 5 bitcoin.
Yes, this is let say "half empty glasses", but we can see "the second half full glasses"  coin is not overpriced and easy to get in, it may be on bottom  we will see, got unique algo (asci resistance), only 2,15mil total coins atm, no ICO/IPO, a few guys care about this coin and is still alive after "crashing" year for many altcoins looking back.

A lot of upside potential if the dev is still working but he has not logged in since July. I don't understand exactly what the coin does but similar coins like Riecoin have started to move up. Website and so on work but without a dev it is a risky shot. True, however in whole crypto it is not easy to find something that is not a risky. That, too, that some "good old" coins begin to bounce back. Sometimes we need months or a year to get profits.
