[LOCKED] cpuminer-opt v3.12.3, open source optimized multi-algo CPU miner

[joblo]

Zcoin-xzc Algo was modified after block 8192 - lyra2z

It's not worth making the change, it will change again soon to something completely different.
For those who compile their own it's a one line change in algo/lyra2/zcoin.c line 11:

Code:

old:        LYRA2Z(hash, 32, input, 80, input, 80, 2, height, 256);
new:        LYRA2Z(hash, 32, input, 80, input, 80, 2, 8192, 256);

Ok, works fine : thank you :-).
Any future optimisation for ZCoin ?

We'll see when MTP comes out.

If I have a good reason to release a new version before then it will include the above change.

Can anyone please give me an .bat example to mine on nicehash?

Needed .bat file example to mine Groestl with your miner.

cpuminer.exe --help. Get the parameters from from the pool you want to mine.

Hi. How to use cpuminer-opt for scryptjane algo at NF 18?

Did you try "-a scrytpjane:18" ?

Edit: That's not going to work. The Nf code is messed up. By default it runs scrypt(N,1,1) with N=2
which works on Nicehsash scrytjanenf16. Looking at the code I have no idea why it works and Nicehash
is down due to lack of orders.

If you know of anywhere I can test I can play with it.

Do you know hows cpu miner Works or Setup a bat file its always the same bat file with only change th - a to your algo you want  example -a groestlcoin  for groestl algo  -a cryptonight for xmr algo

Hi. How to use cpuminer-opt for scryptjane algo at NF 18?

Did you try "-a scrytpjane:18" ?

Edit: That's not going to work. The Nf code is messed up. By default it runs scrypt(N,1,1) with N=2
which works on Nicehsash scrytjanenf16. Looking at the code I have no idea why it works and Nicehash

Thanks for your response.

Have you tried this...

https://bitcointalk.org/index.php?topic=1120634.msg12684868#msg12684868

It looks like the same code I'm using except it sets the N factor automatically.

I know this old miner, it works, but I am curious if in this miner is some optimisations for scryptjane.

It's aready optimized up to AVX2 so it's as good as it gets.

Edit: Upon further analysis of the code scryptjane:18 might work for yac.

When I first ported scryptjane I just did a quick functional test on Nicehash and it worked with default options.
That was good enough and I Ieft it at that. I hadn't noticed that the default NF was 1024 which made no sense
and that Nicehash was NF16.

I'd like to retest at Nicehash with NF16 but the stratum is down due to lack of orders.
I know nothing about scrypt so I have no idea of the effect of the wrong NF. If the wrong NF works
maybe the right one works better.

I'm not that interested in setting up a user on a yac pool just for a quick test but if it works for you I'd
be curious.

-a scryptjane:18 miner say "Unknown algo: scryptjane:18"
-a scryptjane:16 seems to work, but as far I know, there is no coins at NF16 (LEOcoin switched to POS)
to mine scryptjane need to use corect NF for  respective coin

Are you sure the miner isn't expecting N instead of NF? So for NF18, maybe you should specify scryptjane:524288 instead (according to the table in the link you provided)

That's part of it. There is inconsistent handling of N vs NF. The command line parser expects algo:n but scyptjane expects algo:nf.
scryptjane:18 fails because it is not a power of 2.

This is not an area I am familiar with so some suggestions are welcome.

NF seems more user friendly than N. Is it a convention to use algo:n notation or is algo:nf acceptible?

Can software reliably distisguish a NF spec from N spec by its value? For example if the value is not a power of 2 and
is smaller than some limit it is interpreted as NF, else N. What would be that limit?

Any personal preferences on how to handle it?   -a algo:nf    or -a algo -n nf

I still don't understand why the default NF=1024 worked on Nicehash (Leo). This was actually interpreted as NF=2.

As far as I know scryptjane is not scrypt:n, is not only to change N, is different algoritm, in scryptjane algo in miners need to put some aditional parameters --starttime --nfmin and --nfmax, to automaticaly calculate NF, but in some miners is manual you need to put NF --scryptjane:NF.

In Nicehash miner v1.3.0.3 (cpuminer_x64_AVX.exe)  scryptjane algo work corect with -a scyptjane:NF, (tested with YAC -a scryptjane:18)

I mined LEO at NF 16 and before NF 15 ... 14..., but with GPU. If I put cpuminer with -a scryptjane (NF16) to YAC (NF18) miner work but submited shares is rejected.

cpuminer-opt is CPU only. You'll have to search for other threads for GPU miners.
