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.

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:

This was my reference:

https://gcc.gnu.org/onlinedocs/gcc/x86-Options.html

If you have mingw installed you can confirm with:

gcc -Q -march=native --help=target | grep march

Edit: yours looks more like bdver2 or 3.

Edit2: Upon further thought there's probably no need to build bins for AMD. There is no AMD specific code so as
long as the feature set lines up the Intel builds should work just as well.

The following change will be made to the share result output in the next release. There is a small change from
the initial proposal.

[2016-08-31 10:21:44] Accepted 10/10 (100%), 5026 H, 215.37 H/s
[2016-08-31 10:21:44] Rejected 10/11 (99.9%), 5026 H, 215.37 H/s


Small nit:

With the proposed change to the vocabulary after the timestamp, the following metric could also be adjusted.
In the case of an accepted share, you would see the total of accepted shares followed by the grand total of all shares submitted.
in the case of a rejected share, you would see the total of rejected shares followed by the grand total of all shares submitted.

could also change the percentage metric to display the rejection percentage when a share is rejected, instead of defaulting to the acceptance percentage for all shares irregardless of their status.

as follows:

[2016-08-31 10:21:44] Accepted 10/10 (100%), 5026 H, 215.37 H/s
[2016-08-31 10:21:56] Rejected 1/11 (0.1%), 5026 H, 215.37 H/s
...

It makes sense to do both, good idea.

@joblo

indeed, found this (originally japanese) text:

Quote
A description of the GCC source code of "BDver4" before delving into the subject . AMD has publicly the development plan of the architecture than before , until "Excavator" has been revealed . "BDver1" is that of the first generation "Bulldozer" which appeared in 2011 . "BDver2" is "Piledriver" in , are those some of the improvements from the "Bulldozer" has been carried out , has been used in the current FX CPU Ya "Richland" APU. "BDver3" is a CPU core to be used in the "Kaveri" APU of AMD's plans to introduce at the end of this year in the "Steamroller".

so it seems my target needed is bdver2

Please provide more information such as CPU, and compile procedure. The post you quoted was withan AMD CPU and appeared
to be a problem with the compiler detecting the correct CPU architecture.

@Joblo would it be cool with you if I mine to your BTC donation address at nicehash as donation time for your work? I'll mine one full day per week as donation. Every other user can do the same as well.

I just received an anonymous payment at my donation address. Thank you and any others who followed your suggestion.

Smiley That was from nicehash payout. Cryptonight mining has been quite good especially with the fixed rejection issues.
