New CPU Miner!!

I have created a new cpu-miner 64bit and I achieved about 22% more khs/sec .
 
This version is based on cpu-miner-1.2c by ig0tik3d, and plus uses AES-NI/AVX instructions from an other library, so it's usable with this list of Intel Processors:

http://ark.intel.com/search/advanced/?AESTech=true

and with these series by AMD:
    AMD Bulldozer-based processors
    AMD Piledriver-based processors.
    AMD Jaguar-based processors.
    AMD Kaveri-based processors.

I'll release it today, but it's in alpha stage and needs testing because I tried it just with a Sandy Bridge i5-2400 from a friend.

I have not cpus to mine, so bounties for my time will are very appreciated.

Let me know if you are interested.

Windows?

Later, I need time to set the crosscompiler.

dear elmad ... all time i post source code and binary after that claim donations ))) i think you can do the same))

Oh thanks, you are right! I dont ask for donations now or later, I'd want to say that I'll appreciate that later if it works for who use that, because I cant mine Smiley . Anyway, thanks to you, I forked ur project, but if u like, we can collaborate Smiley

You can't mine? Why not?

If you are writing the code of a miner, I assume you have at least one computer (maybe more).

I am mining this coin with just two computers, one of them being equipped with a low-end CPU.

I have just a old notebook. For this version, I wrote the code in this notebook, and compiled and tested on a my friend's computer Smiley .

Doesn't compile under KVM. Sure, there's limited CPU exposure.

It is only 64 bit for now. Your OS in this case is 32bit? I tested with KVM on a virtual Machine, and it's ok. But guest OS needs to be 64 bit for now.

No, it's 64-bit.

Yes, Core 2 Quad doesnt support AES-NI and AVX instructions. I posted early the list of the processors supported. For Intel, from Sandy Bridge and later processors.

What is the cpu of your virtual machine? Could you post your "cat /proc/cpuinfo" ? And, the version 1.2c by ig0tik3d compiles on the same machine? Say me so I can figure out where is the problem.

I guess my virtual machine does not use hardware virtualization. Unfortunately the hypervisor there is out of my control.

As u can see, here misses both avx, aes-ni, and ssse3.  1.2c version by ig0tik3d compiles with this virtual machine?

Is it XEN the host of this virtual machine? I tried just with vmare, and there, with a processor that support VT instructions, the CPU is fully exposed, while there I see that cpuinfo reports a Qemu cpu.

ig0tik3d's version runs without problem. I don't know what the underlying hypervisor is.

Ok, because you have sse2. I was curious just about the message that said "not supporting x86_64".
But sure there is the problem with missing AES-NI and AVX.

From 166 kh/s to 184 kh/s.
So, it is about 11 ~ 12% improvement.

I guess you have generic kernel, right?

With the i5-2400 that I tried, the boost was about 21%

What cpu? And do u compiled with -march=native? Just to know so we can make a statistic. Because, for sure, improvement depends by AVX and AES performances of the processor.

For now this version boost just the echo algo, if I'll have time I want to try to boost some other from the 11 algos Smiley.

Awesome, but I can't find instructions on how to put in march=native?  Where do I do that?  It's not in the readme?  Thanks, and I will donate if I get it running!

Gosh, I am getting old, was reading the install file  Lips sealed

Well, looks like it's running a little bit better Smiley  from 19kh/s  to 23 kh/s  Still, accepteds very few and far between, wish I knew why Sad  Tip on it's way (sorry, I'm not a big holder, but hope it helps Smiley )
