PLEASE CONSIDER THIS:
================

RinHash is really beginning to chart.  This is a new note on a CPU coin, RinCoin, following: "https://github.com/Rin-coin/RinHash-cuda".

The coin has done well for me.       --scryptr

HAVE YOU LOOKED AT ALLIUM?
====================

While digging through GitHub, I came across FancyIX's CCminer 0.51.  With his version, he has improved Allium algo (Garlic Coin, GRLC) by ~50% from TPruvot's CCminer 2.31.  I was mining with a single GPU, an EVGA 1650, and received ~2kH/s with TPruvot's version, and ~3kH/s with FancyIX's.  FancyIX releases his miners for free.

Unfortunately, his miner does not allow for ZIL mining.  I really have adopted the use of Zilliqa mining seriously, and would appreciate if Team Black could add Allium algo.  I am sure you could improve the code to a new level, and you have the most reasonable fee.

Hope things are well with you, the summer is really hot here.  L8r...       --scryptr

USING "-march=native" WORKS
====================

Editing the "build-armv8.sh" script to read "-march=native" resulted in a working executable.  My Rpi-4 now mines "Yescript" algo at ~66H/s, getting a share once every 24 minutes on average.  Slow, perhaps, but Yescript is a top earner on ZergPool today.

Thanks!       --scryptr

It was a brief test, as I sent the Pi units back to mining quickly.  The Rpi-4 also produced a nearly identical error with "Yescript" algorithm.       --scryptr

THE CODE COMPILES
=============

My Rpi 5 and Opi 5 units, also my Rpi 4, have all successfully compiled v24.1.  I used the "ARMv8" build script after finding a hint in the above reply. The "necessary packages" may have been missing.

After using your very latest prerequisite string, the build went to completion.  The executable worked on each unit, printing out help.txt and Version info in each case.  But, the Rpi 4 errored out when attempting to mine YescriptR16, likely due to its incomplete set of crypto instructions.  It is currently mining Zephyr with XMRIG 6.20, slowly.

The Rpi 5 mines Verus at about 4850kH/s, the Opi 5 units at about 6800kH/s.  They are using Oink's ccminer.  I also have some older CPUs mining Verus with Monk's ccminer.

Perhaps you should look into a CCminer-Opt branch?  A fine tune may really improve performance.  Monk's version gets a lot of rejects at times.       --scryptr 

ANSWERING MY OWN POST
=================

The Rpi 5 supposedly has the crypto instructions. See below:

(QUOTE  from Reddit)


"@hyc
 
Amazing that they finally quit being cheapskates and decided to pay for the crypto instruction extension that every other ARM producer in the world has included for the past 8 years already. I wonder what changed their minds.

So it’s another Broadcom chip quadcore with only 2MB L3 cache. I.e., only enough cache to run a single RandomX thread. The other cores will be wasted.

These have always been and continue to be worthless junk. For practical use these days you need closer to 4GB RAM per core, and of course 2MB cache per core. This thing only has enough resources to utilize 1 (core."

END QUOTE)
 
Although I have been able to compile Xmrig on my Rpi 4, none of your recent crypto builds worked.  I finally was able to purchase an Rpi 5 from Adafruit and will try again.

I have several Orange Pi 5 boards mining Verus coin.  I'll be able to check the Rpi 5 hashrate in comparison.

Apologies to the quoted Reddit user.  The post is 5 months old, and from a MoneroMiniing thread.  I have not done a thorough search to verify its validity.

RE: ARM UPDATE --

I tried to compile the latest source on my 8GB Rpi 4, utilizing the ARM build script.  It failed with an error pointing to line 1247.  The line instruction "-flex-vector-conversions" was in the ARM build script CFLAGS portion, so I did not edit that script, I just ran it.

I can run the build and log the entire thing in a text file, or just cut-n-paste the final error details, then pass the log to you in an email, zipped.  Let me know what you might want.       --scryptr

R-PI MAY BE CRIPPLED--

This is an old post from "oink70", who optimized Monkins' Verushash ccminer:

        "Oink70 (2 yr. ago on Reddit)

Mining Verus is impossible on any Raspberry device. The Raspberry company did not license all CPU instructions, so the required functions are not available on Raspberry branded devices.  As far as I know Raspberry is the only brand that crippled the CPU, so any other ARM device should work."

I picked up your recent interest in coding for ARM processors after reading the CryptoMining-Blog post on VerusCoin (VRSC) mining.  I have been able to compile XMrig and tpruvot's CPUminer-Multi on my R-pi.  The above CCminer packages (Monkins & oink70) will not compile.

I am currently mining VerusCoin on a new Orange Pi 5.  Verushash and MinotaurX look like good targets for coding, if you are able to find the right functions.

Raspberry Pi 5 is scheduled to hit the market this month, I believe.  The CPU runs at 2.4 GHZ.

Hope to see some fresh code to match!       --scryptr

ZIL IS NOW ON EPOCH 1--

Use the parameter "--zil-epoch 1" in your command line.  This was addressed in the Discord support thread by the Doc.       --scryptr

DYNEXSOLVE IS THE ONLY CURRENT MINER FOR DYNEXCOIN (DNX) --

DynexSolve will only run on CPUs and nVidia GPUs.  There are no FPGAs or ASICs that can mine DNX.  DNX is not a coin that uses a Cryptonight-based algorithm.

If you have a bag of coins that were once called Dynex, they will likely not fit in a current Dynex wallet.  The information that you post about appears unrelated to DNX as it is mined and traded with the current Dynex softwares.       --scryptr

DYNEXSOLVE IS THE ONLY CURRENT MINER FOR DYNEX COIN (DNX)--

There may be a coin in the past that you are confusing with Dynex Coin (DNX).  The DNX coin is in no way based on a cryptonight algorithm.       --scryptr

MINOTAURX --

First, thank you for the rapid response.  MinotaurX is one of the top 5 in profitability at ZergPool.  As I type this, it is #2, with 3 coins being served. 

Check it out.  The code is already out there, you are the coder with assembly skills.

--scryptr

MINOTAURX --

The CPUminer-Opt docs say that the "minotaur" algo is supported.  Is there support for the "minotaurX" algo, or could it be added and optimized?

Currently, the "minotaurX" algo is rated high in profitability at ZergPool.

--scryptr

ANOTHER SCAM POST WAS ABOVE YOURS AND DELETED? --

Anymore, I just report them.  The mods will delete thame almost as fast as the bots post them.  I have made more than 100 reports that resulted in a scam post deletion.  I just report them.

But, your angry response now points to a good post, I believe.  I am angered by these scam campaigns and mear campaigns also, but the mods are doing their best to contain the truly dangerous posts.  Just report the scam software posts.

--scryptr

UPGRADE TO UBUNTU 18.04--

You need to do a system upgrade.  I did it, it can be done..       --scryptr

USE YOUR PASSWORD STRING--

ZergPool uses the password string to set RigID.  Set the rig name like this:

        "-p ID=1,c=BTC,sd=8" , or "-p bozo,c=BTC"
The rig name is not set as a suffix the the wallet address with a dot separator.  It is set in the password string.

--scryptr

KEEP IN MIND THAT ETH MINING STILL PAYS BEST--

The new GPUs with more than 4GB VRAM will mine ETH.  Miners with older, smaller cards need software that runs on older systems.  The algorithms that you want to incorporate in your miner are just fine for the smaller cards.

Ethereum Classic (ETC) had a spike last week that had it paying second only to ETH.  Not too long ago, before it forked, it paid better.  I just need software that is going to run on my Linux rigs.  VTC is my top earner for my smaller cards, but nVidia is left out.  Software designed for the latest and greatest isn't running on smaller GPUs that fit the algos (VTC, ETC, ZIL) that need less VRAM.

--scryptr

TRADEOGRE LISTS ZANO--

It also requires no listing fees, and is non-KYC.  I really think that the developer for BBR should diplomatically represent BoolBerry (BBR) and encourage the TradeOgre staff to list BBR.  Zano is doing well on their exchange.

Please "keep the family together", get both currencies on the TradeOgre exchange.

TEST RESULTS--

I ran spminer with the flag "-h".  This is what I got:

 "./spminer_cuda10.1: error while loading shared libraries: libcudart.so.10.1: cannot open shared object file: No such file or directory" .

Thanks for looking into things.  I have tried to update the driver in the past and failed.  I may try again, but I don't want to hose up a working system with a failed install.

--scryptr

NVIDIA-SMI RESULTS--

The driver version is 430.26, with CUDA 10.2.       --scryptr
