[LOCKED] cpuminer-opt v3.12.3, open source optimized multi-algo CPU miner

[joblo]

solo mining is not working in ver 3.5 and newer

Did it work before that?

yes for some coins

That's a surprise. I'll look into it.

Actually try adding http://, I changed the default to stratum if you don't specify.

its working thanks

Although I don't support it I don't try to break it either. All this time I've never tried as I don't have many wallets
installed. Thanks for posting.

There is something that I don't understand. If I mining at 252.80 kH/s then what the 5937.08 kH stands for?

I don't understand.

I don't understand.

It's simple arithmetic. It allows you to calculate your work efficiency.

Anybody tried to mine cryptonight coins on CPU i3 4170 3.7 GHz by cpuminer-opt v3.5.5? I want to compare miners.

if you own it you could just run it

have you taken a look at the xmr-stak-cpu miner? without hugepages its only slightly faster than cpuminer-opt, but with hugepages its significantly faster (90-100h/s -> 130-150h/s)

i wondered whether it is possible to also utilize hugepages with cpuminer-opt to gain this significant speedup as well

src is here: https://github.com/fireice-uk/xmr-stak-cpu

i really dont like this miner, no cli options, only config file, no api, only some "web interface", would be great to use cpuminer-opt instead

There are a few issues with large pages, like needing to be setup in the OS, need to run as admin on Win.
I need to investigate further.

yes, i have tested the miner on windows, you will need some os settings to be done for it to work (in linux its the same, but easier through grub, i have not tested it there though)
but you can always fall back to "normal" mining without hugepages, as the miner currently also does
i suppose if hugepages support is possible other memory bound algos can be improved as well, hope you can work the hugepages stuff out for cpuminer-opt

cheers

It's a feature for advanced users, more advanced than compiling from source. there's going to be a learning curve
and a lot of pitfalls. The implementation will require a lot of thought to make the introduction as painless as possible,
for me.

BTW I have a fix coming for missing aclocal building from git. It's now needed with configure now gitignored.
Tarball includes both because they are not deleted by make distclean.
both

XZC (Zcoin) with unit 20500 changes the algorithm.
Will the new version of the cpuminer-opt?

[MAC]Machinecoin. Joblo see that there did doktor83.
It shows the growth in the miner and the pool at 20% ((

By the pool is hard to say. The received hash floats, but the average seems more.

Same question .

[doktor83]

I already implemented new zcoin changes you can download from here with source and binaries:

I'm working on more lyra2 optimizations, not sure how much it will benefit zcoin.
I don't think it will be ready before the cutover, but stay tuned.

Just a straight port of zcoin.

Where's the timetravel source with that huge improvement you claimed?

Not just a straight port, implemented matrix like it was in optiminer version, it gives a speed boost.
You did not have that actually.


I am not giving out the source for timetravel ....yet

I'll be doing better than optiminer, I included the new fully aligned matrix plus a few more improvements
not included in optiminer. 

I also have more timetravel speed coming but may hold back untill you release your source.

@Doktor

something didnt work for me with your sourcecode  

Linux Xubuntu 16.04LTS
i7 2600

im frustrated   hmmm joblo´s source im able to compile in less then 2 minutes   grrr

until i can compile it    running the binary trough wine   looks good
  increase around 180kh/s

EDIT: doesnt like dirty written code , useless  and non exist description of given binary nor source-code , resulted in an switch back to Joblo´s clean and flawless working one

well i worked on windows and compiled on mingw, did not try it on linux tough..

Hey guys, I'm a little pissed right now at doktor83 for using my code for zcoin (it was mine, not optiminer as he claimed)
and not releasing the source for his claimed 40% improvements to the timetravel algo.

So please take this elsewhere.
