The new version 3.1.6 returns only invalid (low-diff) shares with zr5 algo on ziftrpool.io
AKAIK v3.1.5 worked just fine with that pool.

There is some more room for improvement, especially on zr5.

With scmorse/ziftr-cpu which is ig0tik3d/ziftr-cpu with stratum,
I get about 640 khash on Core i7-4790K CPU @ 4.40GHz and with your miner I got as close to 600 khash...

Just my 2 cents. Smiley

Thanks for the feedback, I'll look into it.

Edit: No rejects for me with default options at yiimp. I also reviewed the code and found no changes that would affect zr5.
Can you confirm that 3.1.5 & 3.1.6 behave differently? Could you also try yiimp?

When I mine the diff is reported as .013. You could try setting the diff manually. On yaamp clones it is in the password
string ( -p d=n ), but your pool may be different.

Edit2: I took a look at the scmorse implementation and i might be able to do better. His implemetation does not use the
aes-ni optimized groestl. If I can integrate that it should hash even faster.

Merging my optimizations with scmorse gave a 33% increase to zr5 but I'll wait to release it until your issue is understood.

Well after recompile of v3.1.6 on my Ubuntu box there is no low-diff rejects on ziftrpool.io
v3.1.5 is also good, but little bit (about 5 khash) slower.
Guess it was something wrong with the previous compile...  Grin (I think I used ./build.sh script)

33% more harshrate on ZR5 sounds just AWESOME!  Shocked
I expect that my Core i7-4790K will go upto ~800 khash...
Just to compare - an older GPU, AMD HD6870 makes 860-900 khash average with wolf's GPU miner @ 845 MHz...

I haven't looked at build.sh since the fork, I should clean it up. Thanks for the tip about scmorse.

New in v3.1.8

  - sib algo optimised:
      +116% AES_NI & SSE2
       +63% SSE2

  - nist5 algo SSE optimised, in addition to previous AES_NI optimizations
      +111% AES_NI & SSE2
       +68% SSE2

  - c11 algo +57% optimized for AES_NI & SSE2

Very nice bump in hashrate for ZR5!  Cool

v3.1.7 - goes to 830-840 khash
v3.1.8 - goes to 825-830 khash

Read something about SSE2 optimisations on some algos - does that means that I can use your miner in AMD cpus that have SSE2 (since they lack AES-NI support)?

P.S. You are very welcome for the scmorse's tip. Smiley
Right now I'm making your miner default for my i7 cpu.

Damn!  Undecided
Just when I get my hopes up for AMD cpus...

It wont compile on AMD Phenom II X4 940.

This is the error that I get:
Code:
In file included from algo/cryptonight/cryptonight-aesni.c:2:0:
algo/cryptonight/cryptonight.h:65:6: note: expected ‘uint64_t *’ but argument is of type ‘union hash_state *’

make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/home/***/cpuminer-opt-3.1.7'
make: *** [all] Error 2

Can you do something about that?

In the meantime I will find my cross-compile image so I can try to compile AES-NI and SSE2 win64 builds.

Add "-DNO_AES_NI" to the CFLAGS.

I haven't gotten Windows to compile since I forked from TPruvot, the project file hasn't been maintained.
Good luck.

Thanks!

I used the following:
Code:
./configure CFLAGS="-DNO_AES_NI -O3 -march=native" --with-curl --with-crypto
and
Code:
./configure CFLAGS="-DNO_AES_NI -O3 -march=amdfam10" --with-curl --with-crypto

But it seems that still got an error:
Code:
algo/echo/aes_ni/hash.c:387:4: note: in expansion of macro ‘TRANSFORM’
    TRANSFORM(_state[i][j], _k_opt, t1, t2);
    ^
make[2]: *** [algo/echo/aes_ni/cpuminer-hash.o] Error 1
make[2]: Leaving directory `/home/***/cpuminer-opt-3.1.7'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/home/***/cpuminer-opt-3.1.7'
make: *** [all] Error 2

With
Code:
./configure CFLAGS="-DNO_AES_NI -O3 -march=core2" --with-curl --with-crypto
I got a successful compile on AMD and it mines at 370 khash, which is about 10 khash slower than my scmorse build.

and so far the best is:
Code:
./configure CFLAGS="-DNO_AES_NI -O3 -march=k8-sse3" --with-curl --with-crypto
which gets 373-375 khash on that Phenom II.

P.S. Stall searching my Ubuntu image for cross-compile.
If I don't find it I will use MSYS and Win 7 x64...  Undecided

The SSE2 compile should be on par with scmorse.

Perhaps I should change the recommendation to always use -march=core2 for all non-aesni cpus since it works
on AMD as well.

Nice work, nice bump, went from 890kh/s on this one rig to 940kh/s over 3.1.5 I was using on it.

Nice work, nice bump, went from 890kh/s on this one rig to 940kh/s over 3.1.5 I was using on it.

Intel Duel CPU 21 cores used on EVGA SR2 MB.

Which algo?
Oh lol sorry forgot to say x11

W7 64bit w/ VB Linux

Not sure how that happened, I didn't touch x11. There is no change for me.
Maybe you had fewer processes running.

Don't know either, also 100% out of 1502 summits.
My AMD rig is seeing a small loss 2291 v3.07 down to 2243 v3.1.8
48 cores full Linux 64bit also x11

If this is a NO_AES_NI compile then, yes there were improvements to many algos.

Thanks!
It seems that ZR5 on v3.1.9 AES-NI compile is a little faster than v3.1.7 (about 5 khash)

But decred is just SSE2 on both Intel and AMD - almost same speed per thread on Intel i7 and Phenom II x4 940?
Strange thing is that both of them don't succeed to submit a share for about 5 minutes. (Maybe the network diff is too high now).
