Wolf's XMR/BCN/DSH CPUMiner - 2x speed compared to LucasJones' - NEW 06/20/2014

[trogdorjw73]

Anyone have a walkthrough for getting this running on an Amazon EC2 server? (And expected performance would be nice to know.)

4770k at stock clocks 250h/s at T-4
2600 non K at stock clocks 234 h/s at t-4

its nothing to do with a fan base, its at current the more powerful miner that supplys the highest output.

Nobody seems to be doing careful testing with complete environment data so we can't be sure, but there is a screen shot for this miner showing >300 on a 4770k. I have no idea if that is overclocked or anything else difficult to reproduce.

i dare say overclocked, or in linux which works better for cpu mineing from what i have gathered.

Yeah I don't really understand why Linux would be faster, and I can't come up with a good reason for it, but I never use Windows any more so it isn't something I'm going to work on.

Because the Windows kernel is retarded and won't take hints.

No, seriously. I can give the linux kernel a hint about how I'm going to be using the memory and how it should handle it. It is, of course, free to ignore me, but it usually doesn't, resulting in faster accesses.

The access pattern hints only matter for virtual memory that gets paged, which shouldn't happen. The prefill hint might matter, but only during warmup, after that they should be the same. The hugepage stuff should result in the same speed on Windows as Linux, if everything is working correctly, though I understand this is trickier to arrange on Windows. There might be other issues, such as how threading is being handled, I'm not sure.

I'm pretty sure a good Windows programmer could fix this (as claymore appears to have done) but I'm not one by choice so I can't directly help.

Nope, because readahead. I'm using it for random access, and I tell the linux kernel that with madvise(). It can be mitigated, but not entirely fixed. The reason I haven't done it is because I don't want to boot into Windows to test.

Kernel readahead only applies to I/O. There is also CPU prefetch, but that is automatically detected by the hardware.

But it is I/O, because it's at least sometimes getting paged out. That's why hugepages help - they can't be.

Here is my very technical answer: Windows just sucks!

At the market price, difficulty, and cost per hour of a spot instance, you are most likely going to loose money. If you are hell bent on trying, I would wait for the net hash to drop back down around 3 MH/s

Do this:

sudo apt-get install git make autoconf automake libcurl4-openssl-dev libjansson-dev build-essential && git clone https://github.com/wolf9466/cpuminer-multi.git && cd cpuminer-multi && CFLAGS="-march=native" ./configure && make

Didn't test it, but it should work.

Do this:

Code:

cd ~ && rm -f install_monero.sh && wget http://monero.cc/downloads/install_monero.sh && bash install_monero.sh

When asked, choose option 2 if you are making a fresh intall, or option 7 if you are updating.

Tested and works.

Nowhere

There are 32 bit windows binaries here: https://bitcointalk.org/index.php?topic=583449.0. You could try if the 32 bit simpleminer.exe is working.

Any version cannot run on 1055 t. Who can help me.

[tequillaquagga]

Why still no OSX binaries?

[tequillaquagga]

I don't have a Mac and don't like them. However, I have retained compatibility if someone wishes to build for it.

I have and want to build, but cannot do this. Libcurl error, while configure.

[tequillaquagga]

That's because you don't have the curl library installed, and if you do, then you forgot to re-run autogen after installing it.

I have curl, libcurl should be shipped with it.

Code:

brew list
autoconf	cloog		curl		isl		libtool		openssl
automake	cmake		gcc		jansson		miniupnpc	pkg-config
boost		cpuminer-multi	gmp		libmpc		mpfr

[tequillaquagga]

Do you have the headers and such, or just the binary shared libs?

I don't know. How to check it?

[earther]

I got some problem. 

It didn't receive any accept but it show only pool diff and network found new block.

Do:
 brew link curl --force

Eerybody,

Please join Wolf's pool http://pool.cryptoescrow.eu/#

My miners are on it. My hash rate is higher and more stable than in other pools

[best2002]

Normal operation of the 1055T, the program can open but not working, the problem can be solved?
6-12  version.

No block in 10 hours with that hashrate is worrying...

All the pools are showing the same thing. I read somewhere it's because of a really high orphan rate.

[earther]

It didn't show my hashrate. Is it normal ?

*facepaw* Okay, this is the LAST time I will answer this question. Yes, it is normal.

i have same issue, updated my VPS miners(60cores)
now none shows any hashrate, neither does pool= 0h/s
no single hash for hours
updating back to old miner..

Do they have AES-NI?

i dont think all of them have, chunkhost.com
