Have you tried this...

https://bitcointalksearch.org/topic/m.12684868

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.

Thanks for your response.
-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
Tue, 08 Aug 2017 16:15:28 GMT YAC NF will be 19 http://download.muuttuja.org/yacoin/countdown/
UTC will stay forever at NF 14

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.

Thanks for your response.

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.

i have taken a screen of the interesting part:

There's likely an unallocated stratum session id variable with value "deadbeef......"

Like I said in my previous reply, very strange. Hex code that form highly visible words are often used to help debugging
by making invalid data stick out in a hex dump.

Those hex tags are very useful. The specific deafbeef tag was used in a product I supported and got us into
trouble when we tried to sell to India.

I this case deadbeef is used to initialize a local variable in uint256 code only used by the non-optimized hodl code.
In other words this code does not get run on a 4770K.

The invalid session id also contains two other hex tags: cafe & babe, that are only used in hamsi code which isn't used
by hodl.

It is also interesting that a valid share was hashed with the apparently invalid session id.

These three observations are not related to each other and don't appear to be related to the crash which tells me process
was corrupt. Either the program file is corrupt or the CPU is corrupting data. Since your system is running I assume the
CPU is ok.

Try downloading a fresh copy. I've had no other complaints about the download so it should be ok.
