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

[volapyk]

Thanks for the miner.
Is there any command to reduce the number of cores the miner is using or any other way to reduce heat and efficiency?

Thanks

Yes you can limit the number of threads and there are some other options.
Always check the help: cpuminer --help
Note temperature limit only works on Linux.

Thanks!
I can be a little lazy from time to time.
If wishing donations I recommend adding some coins with cheaper transaction costs than BTC. For instance Pascal Coin - Infinite Scalability.

[freebutcaged]

From what I understand as soon as a coin hits the net there are already too many powerful mining machines started on mining them that makes the

Mining with CPU a complete waste of time, I want to know if there is any coin which gives any profit if mined with CPU? I guess there is none. funny

When someone launches a coin they first look to find a pool before the first block, where and when can we find a coin like Bitcoin? when I think about

It now there shouldn't be any CPU mine-able coin unless they have no value. every CPU coin has it's backdoors implemented somewhere by coders to

Mine with a boost, Bitcoin was the biggest coin and it had one backdoor for miners to mine with %20 more efficiency, I don't trust hundreds of other

Coins, that's why I wont waste my time and energy on any of them, but I will try this to see how it works only to learn something so thank you mate.

I have a 1950X CPU and tested mining monero XMR with cpuminer.
The algo supports AES SSE2 as indicated by cpuminer, but there is no such exe from the release,
we would need something compiled for cpuminer-aes-sse2.exe

When I run it on 26 cores, using the cpuminer-aes-avx2.exe it gives 365 H/s
When I run it using cpuminer-sse2.exe it gives 424 H/s.

Sorry for the dumb question, but if i download the files there is no *.exe to start. Where can i find it?

bat file is present? open it and check the name of the executable file.

Download the binaries, not the source code.

can someone pls recommend DASH coin pool for CPU miner please

[Elder III]

can someone pls recommend DASH coin pool for CPU miner please

You can't mine Dash with CPU, even GPUs are too weak at this point. You will need specialized and expensive equipment to mine DASH. Depending on your CPU, it may be worthwhile to mine different coins and exchange them for DASH instead.

You should repeat your tests, I suspect the difference has more to do with thread mapping that AVX2. There is no AVX2 code
in cryptonight to explain any difference in performance. But your choice of the number of threads makes it impossible to
map correctly to the available cores. It is likely that some threads are bouncing from core to core causing erratic performance.

I recommend trying with 16 threads which matches the cache size and avoids hyperthreading.

You should generally choose the build based on your CPU's capabilities, not the algo. However some users have reported
lower performance using AVX2 on Ryzen CPUs.

I am having trouble compiling it on digitalocean cloudhosting.   I am using the Ubuntu 14.04 drop.   Here is my config.log output.

https://pastebin.com/z1Jh7mRY   

I am not an experienced compiler, so I have no clue what is wrong. I have installed dependencies. $ sudo apt-get install g++ libcurl4-openssl-dev libncurses5-dev pkg-config automake yasm git and done ./autogen.sh

Try following the instructions in RELEASE_NOTES.

Hey joblo, the past few days the Windows Defender antivirus started to flag your binaries. I am not sure if you're aware but that hasn't happened before. Just though I'd let you know.

Thanks for the heads up. There seems to be a recent increase in miners being flagged.

Anyone planning on testing the 7980XE?

[joblo]

Anyone planning on testing the 7980XE?

The specs don't impress me and it's overpriced. It has a low base clock and a relatively small cache, both
critical for CPU mining. Intel is known for better single threaded performance but that doesn't matter when
mining.

The 24 MB cache limits the number of threads mining cryptonight to 12, not even enough to load all the physical cores.
A Threadripper 1920X (12C/24T, 32MB cache) will likely perform better for less than half the price.

Compute intensive algos are irelevant because GPUs are much more efficient and CPUs can't comptete.

The 7980XE doesn't yet have SHA support, unlike Ryzen, but that's less of an issue because there are few algos
that can use it.

It does have AVX512 but I don't see much benefit in that because it only improves compute performance. On those
algos that could potentially use it the gain would be small, less than the gain from AVX to AVX2. There are fewer opportunities
to promote AVX2 to AVX512 because AVX512 works on larger vectors, only algos that use vectors of 512 bits or greater
can use it.

I'm curious for some real results to compare, but I won't be bying one.

Is it just me or is Windows Defender detecting cpuminer-opt as a Trojan:Win32/Vagger!rfn malware?

You conveniently left out the part that explains the legacy version.

Anyway it's virtually useless because the affected algorithms mostly have ASIC miners now or very
efficient GPU miners.

The only people who should consider using the legacy version are those who know what the're doing.
If you have to ask, don't use it.
