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

[MiningTaken]

Hi, need an enlightenment here. 
Does CPUminer-Opt has built-in command line options to set CPU affinity?
Thanks before.

Do you have a link to the calculator itself?

EDIT: Found this useful page.

cpuminer-opt-3.8.5
Added argon2d-crds and argon2d-dyn algos.
sha256t 8 way AVX2 & 4 way SSE4.2 optimized.
CPUs with SSE4.2 get optimizations previously reserved for AVX.

https://github.com/JayDDee/cpuminer-opt/releases/tag/v3.8.5

big move in cryptonight algo with Monero and other fork...
some move to V7, some not....
some be used antiAsic made by Monero Dev team, some(like Sumo Dev) go much deep with antiAsic and move to new algo cryptonight-heavy

can you make and add this algo to cpuminer-opt?

Hello, it seems that avx512 can make a big difference for argon2d: avx512 can reach very high hashrate according to https://docs.google.com/spreadsheets/d/1ZTbJWvvSUu-5ULL-FGCdCuDGwa4SJsj6lj4ns50lJYM/edit#gid=0
with a 7820x (6 cores) can surpass the amd 1950x.

For this processor : 36000 with avx512 versus 28500 with probably avx2.

 With beastpool avx2, I can reach 38 000 with my xeon E5 2696V3 @2,7 ghz.

[Nokedli]

Argon2 SOLO no any accepted block with 3.8.5
No error, cpu usage 100%, but no accepted block.
same with 2x2680v1/Manjaro and 1700x/W10

3.8.4.1 accepting blocks on both config.

I think I found the bug. Argon2 and Argon2d had many name conflicts so I renamed all the argon2
conflicting names, but missed one, so it was calling the wrong version of a function.
I haven't found a pool to test it but it should work in the next release.

So, where did this magnificent AVX512 code come from?

It seems beastpool miner has a AVX512 version at least:
https://github.com/BeastPool/cpuminer-argon2d/releases
the sources are provided, with some info in the file avxdefs.h.

What a farce!

I put the AVX512 code in avxdefs in early preparation for when I start converting the existing
AVX2 code to AVX512.

It's expemimental and ISN'T USED ANYWHERE.

So beastpool forks my code, assumes the AVX512 is active and claims it in his release.
That's either pretty stupid or deliberately deceptive.

Or they didn't release the sources for their avx512 code... Now I have some doubts.

The miner included in the wallet pretend to have avx 512 code too:

cpuminer-opt-3.8.6

Fixed argon2 regression in v3.8.5.
Added x16s algo for Pigeoncoin.
Some code cleanup.

https://github.com/JayDDee/cpuminer-opt/releases/tag/v3.8.6

I plan to remove the AVX Windows binary in the next release.
Please report any concerns with supporting data.

In the wallet miner code (not beastpool miner but the dyn wallet miner): file opt.c, I find this code:
#if defined(__AVX512F__)
static void fill_block(__m512i *state, const block *ref_block,
                       block *next_block, int with_xor) {
    __m512i block_XY[ARGON2_512BIT_WORDS_IN_BLOCK];
    unsigned int i;

    if (with_xor) {
        for (i = 0; i < ARGON2_512BIT_WORDS_IN_BLOCK; i++) {
            state = _mm512_xor_si512(
                state, _mm512_loadu_si512((const __m512i *)ref_block->v + i));
            block_XY = _mm512_xor_si512(
                state, _mm512_loadu_si512((const __m512i *)next_block->v + i));
        }
    } else {
        for (i = 0; i < ARGON2_512BIT_WORDS_IN_BLOCK; i++) {
            block_XY = state = _mm512_xor_si512(
                state, _mm512_loadu_si512((const __m512i *)ref_block->v + i));
        }
    }

    for (i = 0; i < 2; ++i) {
        BLAKE2_ROUND_1(
            state[8 * i + 0], state[8 * i + 1], state[8 * i + 2], state[8 * i + 3],
            state[8 * i + 4], state[8 * i + 5], state[8 * i + 6], state[8 * i + 7]);
    }

    for (i = 0; i < 2; ++i) {
        BLAKE2_ROUND_2(
            state[2 * 0 + i], state[2 * 1 + i], state[2 * 2 + i], state[2 * 3 + i],
            state[2 * 4 + i], state[2 * 5 + i], state[2 * 6 + i], state[2 * 7 + i]);
    }

    for (i = 0; i < ARGON2_512BIT_WORDS_IN_BLOCK; i++) {
        state = _mm512_xor_si512(state, block_XY);
        _mm512_storeu_si512((__m512i *)next_block->v + i, state);
    }
}

And there is some avx512 code in blamka-round-opt.h too.

It appears the AVX512 in the wallet is legitimate but if you look at the beastpool miners page
there's no evidence of any supercharged stratum miners.

I have just checked more carefully on beastpool github: they have added avx512 code (I didn't check if there are some difference with the in wallet miner code for the same opt.c file):

Yes the code is there but it didn't make it into the release even though the commits match.
I can import the code but can't test it.

Does it run in 32 bit computers?
