NEOSCRYPT OPTIMIZATION--

NeoScrypt has become more profitable recently.  I notice that when I launch Neoscrypt algorithm with CPUminer-OPT that it is only optimized with SSE2.  Are there any plans to improve the code with more recent (AVX and later) optimizations?       --scryptr

It uses a lot of Intel ASM, beyond my current skill set. I need to master the concepts
of vector programming and the associated Intel intrinsic functions before I start trying to learn ASM.
I need to do all that before I know if there are any improvements to be made to neoscrypt.
Since neoscrypt already contains SIMD instructions implementing 4-way would be double
the work for only half the improvement. I explained that issue for Lyra2 a couple of pages back.

Short answer, no.

Code:
algo-gate-api.c:156: error: #pragma GCC diagnostic not allowed inside functions
algo-gate-api.c:157: error: #pragma GCC diagnostic not allowed inside functions

Old compiler, edit the file to move those lines (and the third one further below) so they are not
inside the function.

Sorry I'm a novice. Which file - and which three lines - and move them where?

Many thanks

Ok I see 'algo-gate-api.c' is a file and the numbers are line numbers. So what do I do to fix this section?



A few lines before the first errors and a few lines after the last one are the boundaries of the function.
It should look like this.

Code:
// Ignore warnings for not yet defined register functions
#pragma GCC diagnostic push
#pragma GCC diagnostic ignored "-Wimplicit-function-declaration"

// called by each thread that uses the gate
bool register_algo_gate( int algo, algo_gate_t *gate )
{
...
  return true;
}

// restore warnings
#pragma GCC diagnostic pop

cpuminer-opt maximum support only 64 threads CPU? My CPU threads more than 64, how to use it to be able to fully play

There is nothing in cpuminer-opt to limit threads, maybe resource limitations or a system issue.

Good stumble, didn't think of the affinity mask overflowing.

Edit: It looks like this breaks affinity other than default, I don't think 128 bit input works from the cli.
Every affinity I entered turned into -1 even with < 64 threads

I'm often a cynic but the poster removed the post at my request. Thank you.

Edit: what I would have accepted (and still will) is a useful comment or suggestion
with a link for his coin and pool included in his sig. He deserves some credit for being
cooperative.

Hi,
i have downloaded from github. compiled it. and get this:

         **********  cpuminer-opt 3.7.5  ***********
     A CPU miner with multi algo support and optimized for CPUs
     with AES_NI and AVX2 and SHA extensions.
     BTC donation address: 12tdvfF7KmAsihBXQXynT6E6th2c2pByTT

CPU: Intel(R) Xeon(R) CPU E5-2623 v4 @ 2.60GHz.
SW built on Dec 11 2017 with GCC 5.4.0.
CPU features: SSE2 AES AVX AVX2.
SW features: SSE2 AES AVX AVX2 4WAY.
Algo features:.
Start mining with no optimizations.

why does it start without Algo features?

i run it with: ./cpuminer -a scrypt:1048576


thanks in advance.

best regards,
freeapp

I noticed it also with windows binary and same script. Is this normal?

Is it possible add many pools like if i want mine pool 1 but its go down so miner go mine pool number 2?

And return pool1 when up again.

Yes it's normal and dependent on the algo. It means cpuminer-opt has no optimizations for scrypt algo.

Take a look at the retry options in the help. You can use these in a shell script (bat file) to start a backup pool
if the primary fails. There are a few threads in this forum that discuss ways to do this. There also a few GUI
miner manager porgrams that can do that and more.

Yes it's normal and dependent on the algo. It means cpuminer-opt has no optimizations for scrypt algo.

Oh, OK, it's just it previously stated SSE2.

On another subject, I tried 3.7.5 windows binary in my desktop (Ryzen 1700) and all executables fail to start - it states:
"thread xx (random): Scrypt buffer allocation failed Fail: thread xx failed to initiate.

I noted the change in feature reporting in the release announcement.

You're out of memory.  You only have enough memory for xx -1 threads.

cpuminer-opt-3.7.6 is released.

Added lyra2h algo for Hppcoin.
Added support for more than 64 CPUs.
Optimized shavite with AES, improves x11 etc.

Get it on git:  https://github.com/JayDDee/cpuminer-opt/releases

More detailed release notes:

Lyra2h has not been tested. It is virtually a clone of lyra2z so it should work.
Please report any problems.

Support for over 64 CPU is limited in that specifying --cpu-affinity has no effect.
The arg will be ignored and he default affinity will be used. This has not been
tested either so if anyone has the ability to test it please do so and report.

There are no new 4way algos this release but optiizing shavite came as a surprise
and helps all CPUs with AES.

The past two releases have also seen some reworking of some existing SIMD code as
I learn new techniques. It should be more efficient but not likely to produce a significant
speed up.

There are currently 2 4way blockers. BMW is blocking full optimization of x11 and blake256
is blocking m7m. I'd like to get those resolved but I'm stuck at the moment. Since m7m is
CPU only I'd like to prioritize that algo.

A few algos have 4way enabled bur are either untested or have known problems that affect
performance.

Tested working: skein, keccak, keccakc, nist5, tribus.

Enabled untested: skein2, jha, whirlpool, pentablake.

Enabled with known problems: blake256 lane corruption: lyra2z, decred, blake.
These algos operate in 2way mode due to invalid hash in 2 lanes.

Stupid mistake, try this change in algo/lyra2/lyra2h.c line 34:

Code:

<         LYRA2Z( lyra2h_matrix, hash, 32, hash, 32, hash, 32, 16, 16, 16 );

>         LYRA2Z( lyra2h_matrix, hash, 32, hash, 32, hash, 32, 8, 8, 8);
