the cpu doesn't look to have AES: did you try compiling with -DNO_AES_NI?

Even more (x11):

[joblo]

It doesn't support AES, it's a Nehalem.
I think the miner should be compiled with the best "-march" as it will impact the performance of most kernels, regardless how far your optimisations will go.
On a side note, I've found out that -march=native may lead to slower binaries than -march=<the best for your cpu>

AFAIK corei7-avx is tops do you know of anything better?

The best is your right chipset name:

https://gcc.gnu.org/onlinedocs/gcc-4.9.2/gcc/i386-and-x86-64-Options.html

I was looking for something like that. It works down to nocona, only one generation
older than core2 and the first with X86_64. It looks like the legacy code can be tossed
unless I want to try supporting 32 bit. Naaah.

I will include a link to that page in the build instructions.

Edit: Core2 includes SSE4.1 and I recall seeing some hooks for that in the code. I may be able
to define a new second tier for core 2 and better and improve their performance.

Edit2: I tried haswell down to sandybride and none worked. corei7-avx worked. I'll do some
performance comparisons to see if it makes a difference on my haswell.

Did you get that from Wolf0's cryptonight? Yet another thing to look into is all those compiler switches.
Some are obvious by their name but other I have no clue, yet.

Some from Wolf0, some I found myself, some I don't remember...
Some are included into the generic -O optimisation switch: the best to try are -O3 and -Ofast.
The defines could be integrated into the code as defaults, if they benefit most cpus.

Mining with an Intel GPU? I need to look into that.

No source? I want to import the Intel GPU mining. I wanna expand my territory.

Went googling, found out cgminer 3.7 supports Intel GPU mining. Hard to find files,
recent version dropped support.

Found a source file and a windows binary that only does blake256. Haven't got the
source compiled yet but gave the binary a spin with wine and blake at zpool.

It found the GPU, connected to the pool and started hashing, but... all rejects.
Maybe an incompatible form of blake. It's a start.

Why is iy everytime I say I'm going to give windows another shot something
really, really interesting pops up?

[zTheWolfz]

This line seems to have worked will know in a few mins. if it mines. I'm guessing this could be tweaked more if this get its started?

First post your console session with your command line and error messages. *
And stick with the instructions in the READme.md file.

You've got an AMD Opteron 64 so try to find a match

* I can be prickly, so be careful with your questions, This is your first warning.
    I'm not trying to be mean, it just happens, so don't take it personally. Well
    formulated questions with supporting data and a demonstration you did
    your best to solve it will always get the best response (and not just from me).

Getting closer it does start but hangs at checking the CPU.

Code:

h8qg6@h8qg6-VirtualBox:~/Downloads/cpuminer-opt-3.0.3$ ./cpuminer -a x11 -o stratum+tcp://x11.usa.nicehash.com:3336 -u 18tvS3deKZK5q4eTtPRWYeEMWmGmuErHgz.H8QG6 -p d=0.01 -t 1

Only quark and qubit support SSE at this time. Whenever mining
other algos with an SSE2 capable CPU the generic x86_64 miner
will be used.

Checking CPU capatibility...

Ok now I have something towork with. I have a workaround that requires some code changes.
I will explain the changes in detail so you shouldn't have any problems.

First backup the original.

Edit file cpu-miner.c and make the folllwing changes to block the actual check and hard code the
result.

Replace any calls to has_aesni(), has_sse2 with true
There might be a couple of each.

ex:
change "cpu_aesni = has_aesni();" to "cpu_aesni = true;"

You can also set each one to false if the feature isn't supported but try true for both to start.

remove the call to "check_cpu_capability()" on line 3157. Just delete the line.

Save, compile and run. Let me know how it goes.

Edit:It seems your CPU does not have AES_NI to you will likely have to set cpu_aesni to false
in cpu-miner.c and use -DNO_AES_NI.

Time for another story.

The company I worked for produced lage scale mission critical control systems
to institutional customers. They had an emergency response team that provided
24 hour service with a guarantee the customer was talking to an engineer within
5 minutes of the initial call.

The training for this team was interesting and included getting a call from a senior
engineer posing as a cleaner.

He would call and report that hes just a cleaner working near the computer room
and heard alarms. He went into the room and saw a poster with the phone number
to call in case of an emergency.

You can imagine how it went from there. It even involved getting the cleaner to change
circuit packs. One particular trainer would exploit any ambiguity or imprecision in the
instructions to deliverately do the wrong thing. Lots of fun.

I owuld open discussion  with devs and dev wannabes regarding initializing structs.

It may be trivial but considering my inexperience with c/c++ I'm not clear and
a couple of points.

initializing of contexts is a frequent thing in cpuminer and is done by assigning
each field one by one, very inefficient.

There are some shortcuts where a copy if an initialized contex is saved and used
to reinitialze using memcpy, much more efficient.

However I am considering whether assigning a nul version of the struct would be
better.

Ex:

typedef struct {blah, blah,blah} ctx_t;
// init null_ctx at compile time
const ctx_t null_ctx = { null_blah, null_blah, null_blah };
// init my_ctx at run time
ctx_t my_ctx = null_ctx;

Am I on the right track? It might not beat memset but it can handle
non-zero null fields.

Honestly I don't think it makes any noticeable difference.
Initialisation is a very little part of the whole hash computation.

InteI GPU mining with cgminer.

I got the source compiled and it too only does blake256. I tried it and got all rejects
on blake but it works on blakecoin, woopee. But wait, it's not mining with the IGPU
but with my Nvidia GPUs. Crap.

A device query doesn't find the Intel IGPU.

Thoughts?

Honestly I don't think it makes any noticeable difference.
Initialisation is a very little part of the whole hash computation.

I found a measurable difference (<1%) taking the initialisation out of the loop especially the longer
chains with many ctxs to manage. I expect this to have even less. Low priority, I've got better things
to work on.

Tossed away everything I had done with cryptonight and started form scratch.
It took 2 hours to get my first share 180 KH/s.

V3.0.4 coming right up.

Done

Get v3.0.5

Edit: Thanks Wolf0

Edit: I may have overstated the hash rate, more like 170.
