Latest release "cpuminer-multi-wolf-05-29-2014" fails on Win 7 64-bit.

minerd.exe crashes.

I have the same problem too on processors that do not have AES-NI

I have the same problem too on I3 3240 processors!

Well, yeah. The binary was built for processors with AES-NI - there have been no improvements to non AES-NI code yet.

EDIT: Also, the little to no increase in Windows is likely due to Windows having no mmap() function. Therefore I cannot use hugepages (or prefault aforementioned hugepages.)

If you want to damage your brain (even more than if you were to continue your sleep-depravation routine Cheesy

) you could try out using CreateFileMapping / VirtualAlloc and friends on Windows to grab some huge pages. The brain will start to hurt when the windows users complain about it not running without them doing some setup work.

I tried VirtualAlloc and had people test - some said better, some said worse.

Weird, I thought I fixed that. Try using its IP? (62.210.78.186)

I don't want to be a dick, but the OP page is certainly the most confusing I ever read...
A readme file would be good too.

You're not being a dick, it's really disorganized and confusing. Sorry.

Hello there is tutorial for newbies on ubuntu linux for using your miner ?
It will be appreciated.

cheers

I believe davidlatapie has one - it's more or less the same as the original cpuminer.

Hello! I upgraded and recompiled your miner yesterday and it was killed during the night by OOM, because it allocated too much memory:

Any idea?

Yep - known bug, and fixed bug. Re-clone and rebuild.

Code:

./autogen.sh && CFLAGS="-march=native" ./configure && make

And NOTHING ELSE - there are very good GCC flags built in and used by default.

you have -falign-loops=16 twice in there, and -fsplit-ivs-in-unroller is enabled by default in gcc4.4+ Cheesy

Do I? I've been awake for like three days - I'll fix it lol

Wow, I also had both -O3 and -Ofast. I need some sleep.

Ubuntu 14.04, I 4770k diff 10k on moneropool.com, I get same hr as simpleminer.

First, do you have AES-NI? Second, are you using only 7 threads? And third, try using the following to build:

Code:

./autogen.sh && CFLAGS="-march=native" ./configure && make

And NOTHING ELSE - there are very good GCC flags built in and used by default.

Is it faster for all CPU or only for the ones with AES-NI?

Non AES-NI implementation is deprecated. I won't make any more improvements to it, at least not without incentive.

I got an offer to be paid for the non AES-NI implementation... guess I'm on that next.

I don't see any speed improvement, cpu is 3570k.
Solo mining with minerd, is it possible?

EDIT: Also, the little to no increase in Windows is likely due to Windows having no mmap() function. Therefore I cannot use hugepages (or prefault aforementioned hugepages.)

I believe yam miner uses Windows analog of huge pages

I can't see any real increase on the hashrate on my Windows 8.1 x64... Will it be it worth the effort to use this new miner on a Linux virtual machine?

Will I get the 2x (or similar) increase by running the miner inside a unix OS?
