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

[joblo]

The results for nist5 on Ryzen are baffling. I get much better performance with i7-6700K
using 4way and all threads. It's even more baffling that the tribus results on Ryzen are
consistent with Intel. They share a lot of code.

4way 8 threads: 2720
4way 4 threads: 2205
1way 8 threads: 2055
1way 4 threads: 1850

I have i7-7800X CPU @ 3.50GHz

Trying to see which CPU miner is best for lyra2z... anyone know...? I tried 4way and AES-avx2. they seem to get the same KH and KH/s.
For aes-sse42, it seems i get lower.

From personal test, it seems like aes-avx2 is way to go. can anyone confirm? also, what would be safe CPU temperature for CPU mining?

Thanks for that. Do you have a howto guide? I need to file it for when I finally upgrade my build environment

With your permission I will add your link to the OP.

Oh please let this happen!  Been waiting for SHA optimization for Windows since it was available for Linux.

While I understand the link is to the SHA enabled Win EXE, I'm a little weary about using it because it's not from the dev themselves though.

AVX2 is the way to go, 4 way does nothing for lyra2. You can also try reducing the number of threads, it might improve cache
performance. The cooler the CPU the better. Make sure the fan is at 100%, it's cheaper to replace a worn out fan than a burned out CPU.

Hi guys. For using AVX/AVX2 in mining safely on latest Intel CPUs with full thread/core count, use Z170/Z270/Z370 chipset with "avx offset" bios setting. So, e.g. your 4GHz cpu will be running at 3.6-3.8GHz while mining with avx/avx2/4-way on all cores/threads.

To (partly) avoid speed degradation, lock turbo boost speed (if you do not want to overclock, of course) in bios - set max performance plan, disable c-states, disable speed-step. This is supported on non-overclocking chipsets as well (e.g. H270, B250).

Simple benchs for i5-7600 (non-k) for lyra2z330 AVX2 with -t 2:

1) Stock settings (base clock 3.5GHz, goes to 4.0GHz for 2 busy cores) - ~812-824H/s
2) Stock settings + speed-step OFF (base clock 3.6GHz, turbo boost on, goes to 4.0GHz for 2 busy cores) - ~829-836H/s
3) Performance bios profile + speed-step OFF + c-states OFF (base clock 3.9GHz @ all cores, turbo boost on, but it does not go to 4.0GHz) - ~844-861H/s

I may note that this CPU goes to 98C (2C to Tj ) under lyra* with -t 4 and avx2/4-way under 150W TDP tower cooler, so avx offset helps to keep it @80-81C at 3.5-3.6GHz.

So, this just shows that turbo boost reacts slowly, and should be locked for a mining PC. I've tested for cryptonote as well, but the diff is much less - ~0.5% (as there's perfectly stable cores utilization there - no jumping load at all).

I'm cross compiling cpuminer-opt for my own usage for some time (since I posted the instructions here)
You can link to my github
https://github.com/yuzi-co/miners/releases/download/1/cpuminer-opt-3.7.7-4ward.7z

It includes all the windows versions you release (compiled with openssl 1.1) + sha + all necessary dlls

One thing I couldn't resolve is that neoscrypt always fails to run (same in My9bot's version)

[lncm]

Ya, the default affinity was choosing virtual threads instead physical ones. Damn! 6MH/s!

All Ryzen users should take note. Intel chooses one thread per core before using HT.

I confirm major performance increase with Ryzen in scrypt adding --cpu-affinity 0x5555

From 22 H/s to 29 H/s with 8 threads and from 28 to 35 H/s with 15 threads!

I see. Do I have to modify my bat file to run less threads? sorry this is my first time using cpuminer so wanted to see what I need to try to see if I can get the maximum performance.

The option needs to be on the cpuminer command line or in the config file if you use one. If you run cpuminer from a bat
file then yes, you need to add the option to the comand line in the bat file.

Is there a possibility to make a SHA version with AES-AVX/AES-AVX2/4WAY to improve the tests?

Is there a possibility to make a SHA version with AES-AVX/AES-AVX2/4WAY to improve the tests?

There should be no problem adding 4way to the Ryzen build. 4way only needs AVX2 and all Ryzens
have it. Itcould become an issue in the future if some low-budget CPUs are built with SHA but not
AVX2.

Edit: At this time the only algo that can use both 4way and SHA is skein.

is CPU mining zcoin (lyra2z) still profitable? I have i7-7800X 3.5 GHz giving me about 950-971 kH/s where my 1080Ti gives me 3300 kH/s. I could not find easy resources to see if CPU is profitable

see for yourself on http://whattomine.com/coins/175-xzc-lyra2z
on my cpu, core i5 7600k it gives almost 500 khs, which is above 1$ per day (at current difficulty) after deducting power costs

This is perfect. It's exactly what I needed. Since 4way is somewhat stalled right now I tried it out in a Ubuntu-16.04 VM.
I ran the script manually, had to make adjustments for compiler version, and lack or "znver1" arch but I built a 4way with sha.
I just can't run it anywhere.

I just need to tweak a few things and the next release should have the full suite of binaries, with the addition of AVX2-SHA
and 4WAY-SHA.

[joblo]

I've uploaded a new windows binaries package of v3.7.7 to git with support for SHA. I also trimmed some
of the file names to remove redundancy.

4way includes avx2
avx2 includes avx
avx includes aes and sse4.2

It's avaiable on the releases page or this direct link:

https://github.com/JayDDee/cpuminer-opt/files/1569739/cpuminer-opt-3.7.7-windows-v2.zip

Be careful with sha, only the AMD Ryzen family supports it at this time.

Consider this a beta for the new Windows build system.

One thing I couldn't resolve is that neoscrypt always fails to run (same in My9bot's version)

I can look into this now.

Great, now I don't need to compile it every time )
You version is even slightly faster that mine now, and much better than your old one
