If anyone wants this speak up. I'm only doing this once as I have no intentions of forking, but I will
continue to try to integrate argon2 into cpuminer multi.

I'd be interested, please PM me a link. Thanks

Slight change in direction see pallas's post above.

I'm mining scrypt-jane on all my CPU's so it would be very interesting to see the boost
and maybe have a windows version since all my rigs are on W7 at this time, 1 with W10.

What are you using to mine sj? I'm a scrounge, can't help it.
What ever comes in the NiceHashMiner_v1.2.2.2\bin package. Haven't noted the version or who built it.
Edit: cpuminer-muti 1.1

Thanks for your efforts.
But testzcrypto version is not the fastest publicly available Argon2 miner.

Do you mean OPES? Found it, will follow up. Looks like a fork of testzcrypto.

This one:

https://github.com/Encel-US/cpuminer-multi

It includes teztcrypto optisation plus some scrypt-Jane.

Some quick numbers I got from this on a Intel 980X CPU.
Command line used: 10 cores
cpuminer-sse2.exe -a lyra2re -o stratum+tcp://lyra2re.jp.nicehash.com:3342 -u 18tvS3deKZK5q4eTtPRWYeEMWmGmuErHgz.980x -p  x -t 10



Edit: Going by this I didn't see scrypt-Jane as a option?

Maybe it was ccminer or a special version of cpu-miner-multi. I'll look for the source, I think everything
is open over there.

Thanks for the heads up on lyra2, I thought it was dead. Will update the chart with the current numbers (mine that is)

Edit: what did you use for lyra2? It seems to be broken on cpuminer-opt.

Edit: it works in cpuminer-multi 1.2pre so I must have broken it. Something else to do.

However while testing I found lyra2v2 to be working well, 4/4 so far.
I'll update the performance charts.

Edit: 47/47 accepts @ 469kh/s. It's officially supported in v3.0 and the most important missing algo, imo.

Looking great there. I'm about to try to compile v3.0 for testing. Will post once I have some results.

Too late  Tongue now that I have it all setup there's nothing to it.
Cool will DL 3.0.1 now and run some new test.
 Thanks for the heads up.

Edit: did you miss adding the .1 to the new download?
The download says 3.0 so I was unsure if I was downloading the 3.0.1v or the 3.0.0v.

I rushed it out. No point in fixing now. I believe 3.0.1 is in the file name of the tarball.

Maybe a mix up in the links to the new  one? Both I downloaded says 3.0 in the file name & when compiled and ran both show v3.0?

Hello, I wish to ask about the intel co-processors xeon phi. Is there any optimizations, which gain benefits using them?

Bang on. Thanks. fixed it now but he starup message might still display 3.0.
Updated OP

I'll get v3.0.2 out early to clear up the mess but not rushed like this one. Maybe some lyra opts
and one or two new algos supported, already present.

I gave encel a spin. It performs about the same level as my optimizations, we probably made the same changes

Scrypt-jane is not there as a mineable algo, but part of argon2's chain.

Hi Joblo,
Thank you for this initiative. 
I downloaded the 3.0.1 version.
It compiles (and runs) on my machines having i5 processors (Ubuntu 12.04), but it fails to compile on
my Intel Core 2 duo machine (Ubuntu 14.04), as well as on my old Athlon single core machine (Ubuntu 12.04).
Here is the build log (from ./build.sh) from the core 2 duo if interested.

Hi bobben,

Thank you for your interest. You are the first person to report with a CPU without AES_NI support and I only have AES_NI.
as a result cpuminer-opt on older CPUs is untested.

I hope we can work together to get this working. I will download and look at your compile but I'm busy right now
preparing another release. Stay tuned.

X11 Something I noticed Stratum difficulty set to 0.01 works gets shares at nicehash. Anything above 0.01 say 0.02, 0.04  I never get found shares. So perhaps a forced Stratum difficulty set to 0.01 in the command line would be best for some worker hardware. Just so it gets to finding shares quicker. This was on the same laptop in my previous posts in VM. It just goes on & on until the server finally lowers the Stratum difficulty to 0.01 wasting a lot of time & power. If the server Stratum connection timeout it starts you back at 0.04 and more time is wasted until it drops back to 0.01.

X11 Something I noticed Stratum difficulty set to 0.01 works gets shares at nicehash. Anything above 0.01 say 0.02, 0.04  I never get found shares. So perhaps a forced Stratum difficulty set to 0.01 in the command line would be best for some worker hardware. Just so it gets to finding shares quicker. This was on the same laptop in my previous posts in VM. It just goes on & on until the server finally lowers the Stratum difficulty to 0.01 wasting a lot of time & power. If the server Stratum connection timeout it starts you back at 0.04 and more time is wasted until it drops back to 0.01.

I have been told, but I can't confirm, is that you don't lose shares when the difficulty is high since the share submission
is based on hash rate, so multuiply by time to get the share size. Longer time bigger share.

However, the number of stale blocks may go up if the miner does not submit shares on a regular basis.

CPU miners (the people not the program) should all be aware not to expect the same rate of submissions
as with GPUs.

When things settle down I plan on studying hash efficiency, ie how much hash is wasted.

Hi Joblo,
Thank you for this initiative.  
I downloaded the 3.0.1 version.
It compiles (and runs) on my machines having i5 processors (Ubuntu 12.04), but it fails to compile on
my Intel Core 2 duo machine (Ubuntu 14.04), as well as on my old Athlon single core machine (Ubuntu 12.04).
Here is the build log (from ./build.sh) from the core 2 duo if interested.

Hi bobben,

Thank you for your interest. You are the first person to report with a CPU without AES_NI support and I only have AES_NI.
as a result cpuminer-opt on older CPUs is untested.

I hope we can work together to get this working. I will download and look at your compile but I'm busy right now
preparing another release. Stay tuned.

I took a look at your build file and I think I know what the problm is. The package contains code for CPUs with
AES_NI but your cpu can't handle it. The miner can handle this at run time but compiling is the issue.
the compiler option -march=native means to build for your CPU. Since your CPU can't run AES_NI instructions
the compiler refuses to compile it. If we can get it compiled I think it will run fine because cpuminer-opt checks
the CPU architectire in order to select code to run for the correct CPU architecture.

I have an idea for a workaround. We can fool the compiler into think it is bulding for an AES_NI CPU but in fact
we'll run it on your core2. Change the configure option "-march=native" to "-march=corei7-avx" and see if it
compiles. If successful try to run it and note the startup messages regarding the CPU capabilities.

I hope this works.

Edit: Only 64 bit CPU are supported.

A new release is available. Get cpuminer-opt v3.0.2 here...

https://drive.google.com/file/d/0B0lVSGQYLJIZZENfVzlIa1JjeWs/view?usp=sharing

See OP for details, new algos need testing.
