Is this the Cryptonite (M7) XCN support or some other cryptonite? Sorry for that question of a newbe

No, different spelling.

cpuminer-opt does cryptonight algo which is used my monero coin (XMR). cryptonight is also sometimes
called cryptonote.


cryptonite is different,you should look here for it

After a lot of hard work by me and NiceHashSuppport the stale share rejects problem with cryptonight
is in fact a bug in the miner. It was failing to detect new work causing the submission of stale shares.

NiceHashSupport has coded a fix and we are both testing it with good results so far, ie no rejects.

If everything goes well a new release should be avalable within the next day.

I have progress to report for westmere CPU users.

With the help of NiceHashSupport (yet again, many thanks) I have been able to simulate a westmere
compile and have reproduced the compile error reported by users. I have also fixed it. Hodl now runs
AES in westmere. I have yet to test the other AES optimized algos but if it goes well it will be released
with the nicehash cryptonight fix.

cpuminer-opt 3.4.5 is released.

Source: https://drive.google.com/file/d/0B0lVSGQYLJIZVXJ2T0R4QjBWZXM/view?usp=sharing

Windows bins: https://drive.google.com/file/d/0B0lVSGQYLJIZNjlJZEppS2I0YzQ/view?usp=sharing

New Windows bins updated with core2 build.
https://drive.google.com/file/d/0B0lVSGQYLJIZdjFES2M4SDJRQkU/view?usp=sharing

It fixes the stale share rejects mining cryptonight at Nicehash, thanks to NiceHashSupport.

Also fixed, hopefully, is support for Westmere CPUs that have AES but not AVX. cpuminer-opt
should now compile on Westmere CPUs and mine with AES optimizations. A Westmere
Windows binary is also provided. It was compiled using "-maes -msse4.1" options
which should be compatible with Westmere's capabilities, As I am unable to test on actual
Westmere HW I would appreciate any feedback to confirm it now works as intended.

Thanks very much for testing. I will remove AVX from cryptonight algo capabilities in the
next release because there is no AVX code present.

the initial proposal.

@joblo

despite setting the stack size to 1gig (is this enough?) the miner crashed again on two lxc containers, seems to indeed be lxc related somehow as till now no crash has been observed on bare metal ubuntu

will workaround this by just restarting the miner if he dies

also it seems to only affect cryptonight (not lyra2re) so it might be a similar problem to the one you encountered during development

That's curious. My previous stack overflow problem was with cryptonight on Windows. Never had problems with Linux. I removed a very
large buffer from the stack so it should be a reasonable size now. 1 GB should be more than enough.

Try reducing the number of miner threads, see if that changes anything.

also it has definitely something to do with network connectivity, all container crashes were around the same time and in every log there is some info about stratum recv line failed multiple times before the overflow happens

also the overflow is not proxy related, one miner was configured to not use it but my rock solid university network, so the recvline seems to come from nicehash stratum servers having problems (?)

3.4.5 (cryptonight) works for me on windows 7 with hashwell & sandy bridge with nicehash&dwarf. No more screen full of stratum connection fails like in 3.4.4.

If I were you I would add xmr address to my sig.

AMD, not so sure. amdfam10 still won't compile, trips up in AES code. I haven't heard from any AMD users recently to know
what works and what doesn't.

Working in the sense that there is a useable miner and it can use the CPU's best features.

Excellent tip but I'm surprised it works, amdfam10 doesn't have AVX. It doesn't have SSE4.1 or SSE4.2 either which is where
I think my compile is blowing up.

It's a good idea to try the Inlel builds on AMD CPUs.

3.4.5 (cryptonight) works for me on windows 7 with hashwell & sandy bridge with nicehash&dwarf. No more screen full of stratum connection fails like in 3.4.4.

If I were you I would add xmr address to my sig.

Thanks for testing. It looks like I have all Intel CPU nailed down.

AMD, not so sure. amdfam10 still won't compile, trips up in AES code. I haven't heard from any AMD users recently to know
what works and what doesn't.

working in which regard?

for my A6-6400K (amdfam10) i use core-avx-i, seems to result in the best hashrates

Working in the sense that there is a useable miner and it can use the CPU's best features.

Excellent tip but I'm surprised it works, amdfam10 doesn't have AVX. It doesn't have SSE4.1 or SSE4.2 either which is where
I think my compile is blowing up.

It's a good idea to try the Inlel builds on AMD CPUs.

the A6 is amdfam10 right? it definitely has AVX:
