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

[joblo]

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.

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

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.

That where the confuision arises, scrypt:n vs scryptjane:nf. I can make the software work either way so that scryptjane:18
and scryptjane:524288 would both work. It's a simple conversion: N = 1 << (Nf+1). The only question is whether there is any
overlap where the same value could represent both a valid N or Nf.

Do you know the lowest N value and highest Nf?

I don't like the automatic NF setting because it requires 3 parameters instead if 1. It may work well if always mining the same
coin but is more complicated when switching coins.

Thanks, anything less than 32 in Nf, everything else is N. I can work with that.

cpuminer-corei7-avx- i3 refused to work, but it works well on cpuminer-corei7

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);

I had to learn on the job Mingw64

Are there any improvements to make by building it with gcc-6 over gcc-4?

fx6300 and i3 which is 5% faster on gcc 6,2

Your i3 is probably first generation which doesn't support AVX. It's good that you can now compile, a native compile is
usually always best.

Thanks for the info about GCC 6 performance.

cpuminer-opt v3.4.12 is released.

Lyra2z is updated to mine zcoin from block height 8192 until the next time they change the algo.

Scryptjane is fixed to support different N factors, ie -a scryptjane:18

You might be the first to try Ubuntu 16.10. How did you compile? Did you try the compiler's suggestion "recompile with -fPIC"?

[joblo]

In view of the seemingly never-ending problems with the Groestl SSE2 macros (see previous post) I am proposing removing
them from future releases of cpuminer-opt.

These macros are used by algos that have a Groestl function if the CPU does not support AES. All these algos will use the
AES optimized Groestl function if the CPU supports it.

All agos will still be mineable with a reduction in performance on CPUs that don't support AES when mining
any of the affected algos.

The following algos are afffected: X11-17, quark, nist5, zr5, hmq1725,

These algos are considered legacy as are non-AES CPUs. Any affected users can continue to use older versions of
cpuminer-opt.

Removing these macros should result in fewer compile problems when migrating to newer systems.

Zoin uses a memory hard algo meaning it makes many memory accesses, so much that the CPU has to wait for

It's like being on a congested highway. A bigger engine won't help you go faster.

That is, I balk at the limit of memory bandwidth?

Work virtual machine hyper-in does not limit the maximum performance of the processor?

Yes, memory bandwidth is the limiting factor.
