Topic: [ANN]: cpuminer-opt v3.8.8.1, open source optimized multi-algo CPU miner - page 102. (Read 444067 times)

core2 seems more appropriate than corei7, but i also like plain cpuminer-sse2.exe

yes of course looks better and clear to understand .  thanks for your effort

still on testing OLD Oranges report will follow soon

no need for further testing , as the greedy Sharks are inside the pond , diff raising up , coins worthness going down ,  nothing worth anymore for
cpu-mining . 

Next algo dead for CPU´s

maybe  I'll go with cpuminer-core2-sse2 for more clarity. What do you think? I want to get it right and be done with it

alright

i actually dont have a script to change, rather my miner paths would need to be changed on each computer (they are not hardcoded/in the sourcecode), so i will note that and just rename the sse2 file on each new version when i manually push it in my bin repo

Oops, you're right, corei7-sse2, next time.

Still wrong, it's permanent name is cpuminer-core-sse2.exe

Edit: maybe  I'll go with cpuminer-core2-sse2 for more clarity. What do you think? I want to get it right and be done with it.

in the new dl its still *-corei7-sse2.exe (or did you mean "Your script should expect cpuminer-corei7-sse2.exe from now on"?)

sse2 was intentional naming becaused it's used so often on AMD, I messed up last time calling it core2.
Your script should expect cpuminer-sse2.exe from now on.

New binary download link:

https://drive.google.com/file/d/0B0lVSGQYLJIZbk9jM3FaUWJvUDA/view?usp=sharing

so its only the renaming i assumed for both? in that case no new dl link is needed, ill just rename them

Let me fix that.

Edit: it's just a naming error in my build script with cpuminer-corei7-sse41, drop the avx2.
sse2 should be there.

I'll provide a new dl link.

the naming scheme changed again?

*-sse2.exe missing
*-corei7-sse41.exe missing

*-corei7-sse2.exe new
*-corei7-sse41-avx2.exe new

am i right to assume that they are the same arch, just different names?

*-sse2 => *-corei7-sse2
*-corei7-sse41 => *-corei7-sse41-avx2

cheers

cpuminer-opt 3.5.6 is released.

https://bitcointalksearch.org/topic/m.13542056

./cpuminer -a hodl -o stratum+tcp://erc.suprnova.cc:7674 -u worker.worker -p ppppp -t 4

./cpuminer -a hodl -o stratum+tcp://erc.suprnova.cc:7674 -u worker.worker -p ppppp -t 8

.

sorry my ignorance, but where? because ....   for example on  ~/nheqminer/nheqminer/build $ ./nheqminer -l zec.suprnova.cc:2142 -u worker.worker -p ppppp t4      = t4 4 miners threads  work for me in nheqminer... but dont know how put only 4 in cpuminer-opt-3.5.5  ./cpuminer: unsupported non-option argument -- 't4'


--help will tell you  that -t sets the number of threads

when --help

and you say
You might also want to recompile to take advantage of AVX2.

thanks, but how i can do that?   , any link or location  


. thanks for your help @joblo ..

--help will tell you  that -t sets the number of threads.

You might also want to recompile to take advantage of AVX2.

hi
need help for run only 4 miner threads , not 8 miners

thanks for your help and the work here.

Haha. Yes that happens some times, not much interest to miners, mostly other devs.
I'm an experienced programmer, but not an experienced "C" programmer. As a result
I get hung up a lot on some of the C quirks, such as pointer arithmetic. Bugs in pointer
arithmetic always take me the longest to find and I seem to make them a lot.
I think it's evil. Just venting.

Things are much better now. Performance boost is better than expected. just testing left to do.
I managed to squeeze a little more juice out those old oranges.

im sorry but all you wrote is spanish village (nur Bahnhof) for me , even i dont understand this , i believe you makes the right decision and deliver us a good and stable release as usually
thanks a lot for putting so much time and headache into this 

Pointer arithmetic strikes again. It caused the stack smashing when I was up scaling a pointer
offset to AVX size and messed it up badly, thought I was converting from uint64_ when it was actually bytes.
I inspected that function many times carefully but everytime I was thinking uint64_t to __m256i.

Lyra2z now works in AVX and I assume on Windows too.

One more tweak to do, then cleanup and full test. Should be released tomorrow.

This will likely be the end of any Lyra2 optimizing. AVX2 is fully done and AVX has only one function left
to convert. It's a difficult one and it's only AVX so it would only be for the learning experience.
It's at the point now that being too aggressive with manual optimizing is having a decreasing benefit
and increasing risk.
