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?

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?

Think any of this would help me to get a completion compile on the problem AMD system I posted about a few pages back?

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

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.

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=

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.

not exactly : http://ccminer.org/slackex/
Cool. I didn't mean slack was obsolete, just that people who like it are old school.
I've played with it but never any real work. At one time I had 8 different distros
multibooted on 2 20GB HDDs running on a pentium 1. Now the're all in VMs.
A guy I used to work with was a slackware fan. Give him the keyboard, toss the mouse,
and he could do magic. He's was also pretty sharp in networking, knew his protocols
inside out.
I started using Linux with Slackware 2.0 :-)
RH 5.2 for me, bought the CDs. I discovered Slack around v5 or 6, when PV was sick
and out of action for a while.

Nope, it's a bug. I think it will be irelevant when I implement X86_64 compiling.
But "-march=x86_64" won't configure. I don't know if it's the wrong target name or
if GCC has dumped support for it. Maybe I need to install some compat packages.
Edit: just checking your output again. even though it says no for SSE2 it should
still the SSE2 kernel. Formyour hashrate it appears to be normal for and i5 SSE2.
I guess the early corei didn't have AES_NI. Do you want to give it try to make sure?
Just edit cpu-miner.c:1949 and hardcode cpu_aesni=true. Then compile with AES_NI
enabled and let me know if it works.
Thanks
I intalled the x86_64 cross compiler and it still doesn't work.

Is it correct that "SSE2: No"?
AFAICS, it runs fast anyway.

Nope, it's a bug. I think it will be irelevant when I implement X86_64 compiling.
But "-march=x86_64" won't configure. I don't know if it's the wrong target name or
if GCC has dumped support for it. Maybe I need to install some compat packages.
Edit: just checking your output again. even though it says no for SSE2 it should
still the SSE2 kernel. Formyour hashrate it appears to be normal for and i5 SSE2.
I guess the early corei didn't have AES_NI. Do you want to give it try to make sure?
Just edit cpu-miner.c:1949 and hardcode cpu_aesni=true. Then compile with AES_NI
enabled and let me know if it works.
Thanks
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=
AFAIK corei7-avx is tops do you know of anything better?

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