Intel xeon 1.7ghz for cryptonight . Only 3.04 H/s.

Can I optimize something?

In Cryptonighte good result is 60-100 H\s on one core. My i7-2600K  360-400 H   .  xmr stak  or xmrig . Need cpu affinity for best result

I'm mining Intense Coin. How can I optimize for Intel XEON E5-2650L v4?

Need write cpu affinity . U have 35Mb and will work 17 threads. Use XMR stak or XMrig.

And need
* LARGE PAGE SUPPORT
 * Large pages need a properly set up OS. It can be difficult if you are not used to systems administration,
 * but the performance results are worth the trouble - you will get around 20% boost. Slow memory mode is
 * meant as a backup, you won't get stellar results there. If you are running into trouble, especially
 * on Windows, please read the common issues in the README.
 *
 * By default we will try to allocate large pages. This means you need to "Run As Administrator" on Windows.
 * You need to edit your system's group policies to enable locking large pages. Here are the steps from MSDN
 *
 * 1. On the Start menu, click Run. In the Open box, type gpedit.msc.
 * 2. On the Local Group Policy Editor console, expand Computer Configuration, and then expand Windows Settings.
 * 3. Expand Security Settings, and then expand Local Policies.
 * 4. Select the User Rights Assignment folder.
 * 5. The policies will be displayed in the details pane.
 * 6. In the pane, double-click Lock pages in memory.
 * 7. In the Local Security Setting – Lock pages in memory dialog box, click Add User or Group.
 * 8. In the Select Users, Service Accounts, or Groups dialog box, add an account that you will run the miner on
 * 9. Reboot for change to take effect.

At now for my 4690k @4700GHz on lyra2z algo the best is 3.8.1 - 522.17 kH/s, 3.8.2 gives me only 505 kH/s

I backed out a previous optimization from Lyra2 because I couldn't get allium to work with it. It didn't
seem to affect other lyra2 based algos so I may reenable it once I understand more.

[host21]

Thanks, i configure XMR stak, but I only have 1 core.

I put in config.txt "cpu_threads_conf" :
[
    { "low_power_mode" : false, "no_prefetch" : true, "affine_to_cpu" : 0 },

And hash is the same

[Enth]

joblo, allium has more profit then lyra2z?

OMG   Xeon have 28 threads. Write 17. U write cpu-affinity 1 thread and its wrong. Need all 17 . And download  xmr stak 2.2.

Ok, Thanks for your help

Which coin is the most rentable to mining with cpuminer-opt?

[Manato]

Hello,

first of all: Great project, thanks joblo - you're the man! Great community and thread here as well!

The reason for my post is that compiling from source fails. My setup: Windows 10 & cygwin. Tried with mingw_w64 and msys but I couldn't get it to work.

I'm not really familiar with compiling C/C++ stuff, so I'm sorry if my question is somehow stupid or whatever. Please be kind I also hope that I provided all the needed information.

I'm pretty close to compiling the final .exe file. It fails though. The output is:

Code:

/usr/lib/gcc/x86_64-pc-cygwin/6.4.0/../../../../x86_64-pc-cygwin/bin/ld: cannot find -lpthreadGC2
collect2: error: ld returned 1 exit status
make[2]: *** [Makefile:1748: cpuminer.exe] Error 1
make[2]: Leaving directory '{{MYPATH}}/cpuminer-opt-master'
make[1]: *** [Makefile:5412: all-recursive] Error 1
make[1]: Leaving directory '{{MYPATH}}/cpuminer-opt-master'
make: *** [Makefile:859: all] Error 2

Where

Code:

{{MYPATH}}

of course is the directory where

Code:

cpuminer-opt-master/

is located.

Does anyone have an idea how to fix this?

Thanks

/usr/lib/gcc/x86_64-pc-cygwin/6.4.0/../../../../x86_64-pc-cygwin/bin/ld: cannot find -lpthreadGC2

That's the same problem I have with CygWin, there is no mingw package for pthreadGC2. Or there wasn't
the last time I dug into this. But this looks new:

I'm very busy but if you give it a try let us know how it goes.

Hi joblo !
Have you looked at Arionum ? Will your great miner support it soon ?

No way, it's completely different.

Thanks for the link, joblo. I played around a little bit, unfortunately I had no luck so far. As soon as I find out something or even can compile the .exe in cygwin I'll let you know.

Anway, your answer was very helpful since I now know that there is not an easy fix I have overlooked.

Cheers

For some reason I'm getting lots of duplicate shares on HOdl (windows avx2 version)
First time I'm noticing this, and I'm pretty sure that didn't happen before 3.8.2

I made a small change to hodl in 3.8.2 to eliminate a compile warning but if that was a problem I'd
expect invalid shares, not duplicates.

I've tested v3.7.0 and it produces duplicates as well. I suspect a problem with Nicehash. Hodl has not
seen a lot of changes and is mostly self-contained so it's unlikey it would have been affected by other work.
