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

[joblo]

This was my reference:

https://gcc.gnu.org/onlinedocs/gcc/x86-Options.html

If you have mingw installed you can confirm with:

gcc -Q -march=native --help=target | grep march

Edit: yours looks more like bdver2 or 3.

Edit2: Upon further thought there's probably no need to build bins for AMD. There is no AMD specific code so as
long as the feature set lines up the Intel builds should work just as well.

The following change will be made to the share result output in the next release. There is a small change from
the initial proposal.

[2016-08-31 10:21:44] Accepted 10/10 (100%), 5026 H, 215.37 H/s
[2016-08-31 10:21:44] Rejected 10/11 (99.9%), 5026 H, 215.37 H/s

Small nit:

With the proposed change to the vocabulary after the timestamp, the following metric could also be adjusted.
In the case of an accepted share, you would see the total of accepted shares followed by the grand total of all shares submitted.
in the case of a rejected share, you would see the total of rejected shares followed by the grand total of all shares submitted.

could also change the percentage metric to display the rejection percentage when a share is rejected, instead of defaulting to the acceptance percentage for all shares irregardless of their status.

as follows:

[2016-08-31 10:21:44] Accepted 10/10 (100%), 5026 H, 215.37 H/s
[2016-08-31 10:21:56] Rejected 1/11 (0.1%), 5026 H, 215.37 H/s

It makes sense to do both, good idea.

@joblo

indeed, found this (originally japanese) text:

A description of the GCC source code of "BDver4" before delving into the subject . AMD has publicly the development plan of the architecture than before , until "Excavator" has been revealed . "BDver1" is that of the first generation "Bulldozer" which appeared in 2011 . "BDver2" is "Piledriver" in , are those some of the improvements from the "Bulldozer" has been carried out , has been used in the current FX CPU Ya "Richland" APU. "BDver3" is a CPU core to be used in the "Kaveri" APU of AMD's plans to introduce at the end of this year in the "Steamroller".

so it seems my target needed is bdver2

cheers

Tried compiling on a non-aesni cpu (core2), but it tries to use  aesni on cryptonight:

Please provide more information such as CPU, and compile procedure. The post you quoted was withan AMD CPU and appeared
to be a problem with the compiler detecting the correct CPU architecture.

@Joblo would it be cool with you if I mine to your BTC donation address at nicehash as donation time for your work? I'll mine one full day per week as donation. Every other user can do the same as well.

I just received an anonymous payment at my donation address. Thank you and any others who followed your suggestion.

[Epsylon3]

me too maybe the same source...

[pallas]

Me nothing.... nobody mining M7 on nvidia? :-/

[Epsylon3]

i think i was 2 years ago

That was from nicehash payout. Cryptonight mining has been quite good especially with the fixed rejection issues.

@joblo, here is small 0.1 BTC donation for your excellent work on cpuminer-opt: https://blockchain.info/tx/6a77b6ea11cb901741b3d3dae4d714a28dc120f7591a6372a91af5924145ab96

Is it possible to opt the cryptolight algo 

[aquelol]

hi, just a report on notebook haswell cpu (4700MQ @ 3.4ghz 47W)  with espers mining (hmq1725)

v3.3.x-v3.3.8 Start mining with AES-AVX optimizations =150/155 Kh/s ; 3.4ghz core/cache and ~46W no throttle  (stable optimised voltage/temp 76° max )
since v3.4.x Start mining with SSE2 AES AVX AVX2 = 140/145 Kh/s ; 3.4ghz core / 3.2ghz cache and +47w with some cpu throttle down the hashrate to 130 Kh/s and +85°


i have a question, i wanna try to solo mine but your client crash  when request/receiving getwork (tested with all 3.3.x/3.4.x)

log 3.4.5 crash

Thanks for testing. cpuminer-opt only supports stratum mining.

I am curious about your performance results. Can you provide more info such as whether you compiled you own, Linux or Windows,
or used precompiled binaries. Thanks.

[joblo]

thanks for the great work!  
Is it possible to opt the cryptolight algo  

Cryptolight is not a very popular algo and until recently I didn't even know there was a coin using it.
Therefore it is very low on my priority list. I haven't analysed the code so I don't know if the
cryptonight optimizations can be ported for use on cryptolight. If they can it might be possible for
me to implement it. Otherwise you will need to pay someone like Wolf to build one for you.

I am pretty busy keeping up with new algos, while trying to opitimize the more popular
existing algos. It is unlikely I will get to cryptolight any time soon.

Edit: I took a quick look at cryptolight and it appears to already have AES optimizartions implemented.
You can confirm this by testing on a CPU with AES_NI using the SSE2 build of cpuminer. If it is slower
than the AES version for your CPU then you are already using AES_NI.

[maxfunky]

Thanks joblo will try see if there is a dif..
btw I just find this https://github.com/Arux-BTT/CPUMiner-Multi-cryptonight-light/releases/tag/04082015 [with AES-NI] but I wanna keep using your version of cpuminer. I can use it easily on linux VPS (I'm kind of a noob with linux cli..lol)

I guess that means it is working and I can take out the warning about it being untested? If your tests show the AES build is faster than
SSE2 I'll change the display to indicate the algo has AES.

I haven't look at the Arux-BTT fork yet, let me know how it performs compared with cpuminer-opt.

[maxfunky]

yes you can take out the warning
