It's fully utilizing the cores (minus one for some reason... maybe the scheduler thread is included in the thread limit?) so I can't see a huge gain other than running it on bare metal.

The opteron cores are not as efficient per ghz as the haswells.  The only advantage is that you have physical cores without any hyperthreading.  I'll try and compile the miner on 12.04 to run it on bare metal and see what/if any advantages are seen vs running it kvm with cpu passthrough.

The server is about $3300, so it's not exactly cost effective.  Just fun to see.

edit: just noticed the instructions to install it on 12.04, derp.

What do you get when running on only 24 cores ?

Is that the 16 core Intel system or the AMD 48 core?

methinks its the Opteron machine.

Wolf0, thanks for sharing.  I should not be surprised that the coder of the miner is very effective at managing his rented rigs, and I am not really, but I gotta say that your ~64 h/s/core is quite impressive on the c3.8xlarge instances.

Actually, I can get 70H/s/core on c3.8xlarge, 64H/s/core is just with this miner...

I get 64H/core on my opteron...  the speed actually tops out at 26 cores (26*64=1664H/s same as in the screenshot).  I guess that's L3 bandwidth limit - It's amusing to see how intel and amd are virtually identical per core due to this similar cache speed limitation.  Pushing numactl to force workloads onto physical cores/cache pairs didn't make a difference.

i5-3450 windows 7

Downloaded both the 06-09-2014 Wolf miner and the LucasJones miner.  Wolf is 5% faster according to the numbers the miners display.

Anyone have any ideal performance/cost CPU desktop/server builds for XMR?
Thinking about buy a new single/dual CPU setup for this + gaming rig and GPU mine also.
AMD has some cheap setups, but don't want to waste money, but I also want to buy something on newegg with BTC....though the 10% discount expired I think =(

I'm uncertain of the CPU side (cost vs performance).

GPU wise, merged mining (XMR+FCN) on a GeForce GTX 750 Ti hits 220->250 h/s. (can probably get more if its just dedicated to that as I'm running it inside of Linux as a desktop)
At the moment its the fastest GPU per watt of power used and its relatively cheap.

I believe there's a configure option for that...

When I start CPU miner with i5-3350p have just only 75 h/s. I changed threads from 1 to 4, always same??? What is the problem???

edit: now have 120 h/s, hope it is ok now?

I didn't try 1 or 4 threads but did try 2 and 3 threads with an i5-3450 with 3 threads being slightly faster.  Windows 7

I new to mining, I want to make sure this is working ok. Here is what I get when I start mining.

[2014-08-26 02:13:39] thread 0: 490 hashes, 48.25 H/s

[2014-08-26 02:13:39] Stratum authentication failed
[2014-08-26 02:13:39] ...retry after 10 seconds

Do I have to worry that authentication failed? If so what am I doing wrong. The reason I asked is I tried several pools and got the same failed message. So I assume that is part of the mining, or is it>

Yes worry because it's not working.  It's not the pool. 

Most likely there is a space in your wallet address when you copy and pasted it.  I think it happens because the address wraps to 2 lines in the wallet and it is not always obvious when you copy it especially if it is on 2 lines in the bat file.

Let me know what happens.
