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

[joblo]

I still have a lot to learn about c/c++. I got burned by pointer arithmetic this week. It seemed only logical
to me that  "p + n" would be a byte offset while "p[ i ]" would be scaled. Surprise, the're both scaled.

My next issue is how to consolidate the definitions of frequently used text strings. In my native language
it's a simple matter of defining the strings in a header file and referencing them in many source files. This approach
causes multi-def warnings in c/c++.

I often see #define macros but they result in the strings being copied by every reference.

Does anyone know of a way in c/c++ to have one definition with multiple references that don't make copies?

-fmerge-constants
Attempt to merge identical constants (string constants and floating-point constants) across compilation units.
This option is the default for optimized compilation if the assembler and linker support it. Use -fno-merge-constants to inhibit this behavior.

Enabled at levels -O, -O2, -O3, -Os.

Thanks Pallas.

The description of this option indicates it tries to merge multiple explicit definitions of the same constant which means
I'm worrying about nothing. I'm trying to merge explicitly defined identical constants by making a single
definition while it seems the compiler will do it transparently. Outsmarted by the compiler again, I just wish things
wouldn't break when the compiler overrides my code.

cpuminer-opt v3.2.3 is released.

More restructuring, code cleanup and bug fixes. This should be the best release yet.

is this better than the wolfo version for hodl and esper?

is this better than the wolfo version for hodl and esper?

It should be equal to Wolf0 on hodl and esper is not implemented yet.

Edit: I'm taking a look at espers and i think I can improve it.

cpuminer-opt v3.2.4 with support for hmq1725 (espers).

https://drive.google.com/file/d/0B0lVSGQYLJIZY1BVV1RGZFlJclU/view?usp=sharing

it's 56% faster than cpuminer-hmq1725 on CPUs with AES_NI, 17% faster with SSE2.
I recommend using the GPU port at suprnova, the CPU port has a rough start before the diff
settles.

You can use Virtualbox to create a virtual Linux machine, same performance if you allocate
all CPUs to the VM.

What do you need to know? Everything should be in the README.md file. Debian should be no problem, nor any other
major distro. I didn't mention it because I assumed most Windows users would find Ubuntu less intimidating.

So, here's the tentative plan:

1. set up a new VM with all cores and 4 or 8 GB of RAM
2. install Debian on it, probably a net install of Debian 8
3. run build.sh
4. install whatever coin wallet software and set it up so I can mine to localhost.

This is almost what I do with my Windows VM; installed Win 10 on it, downloaded the wallet software, and ran three different versions of cpuminer on it. (I come from the ESPERS thread, there have been 3 versions of cpuminers there I think.)

I run Windows Server 2012 R2, so I use Hyper-V on one of my little boxes. I got it cheap, used, something like $600 USD for a dual quad core 48 GB ram rack server.

Only stratum has been tested so I have no idea how it will behave if you try anything else.

The miners I tried used getwork gbt version 112. This fork should work similarly. I'm willing to do the testing. I've been solo mining ESPERS.

I appreciate your offer to test. Looking forward to your results. I hope I haven't broken anything.
