a reference to the algo details helps

Thank you guys, I'll give a try with Docker...

Excellent )

significant improvement in SH256t (9mh -> 32mh)
argon2d algos seem somewhat slower than the reference on avx2 / windows

AMAZING!!! Thank you!

@joblo

Can you add new algo x16s?

cpuminer-opt-3.8.5

Added argon2d-crds and argon2d-dyn algos.
sha256t 8 way AVX2 & 4 way SSE4.2 optimized.
CPUs with SSE4.2 get optimizations previously reserved for AVX.

https://github.com/JayDDee/cpuminer-opt/releases/tag/v3.8.5

i'll be waiting for argon2d)

Too many requests for algos, I don't respond anymore just to say no. If I'm interested you will know
soon enough.

Feel free to post of a new algo you believe will fit with cpuminer, the more info about the algo the better.
The best references are C source code of a working unoptimized example.

Typical reasons why I won't implement a given algo:

1. Requires a complete rewrite.
2. Existing miner is already optimized.
3. Lack of details/specs about the algo.
4. Lack of support by pools, exchanges, etc.

Hi JayDDee,
Over 70 algo with CPUMiner-opt : very good, congratulation :-).
But one of the most popular is not in : EquiHash.
Is there any chance to have one day EquiHash in CPUMiner-opt ?

Hi Dev,
I will ask the same question as above:
Do you have any intentions to add sha224 that Bismuth algorithm is using: https://bitcointalksearch.org/topic/annbisbismuth-20-beyond-defi-1896497
How hard will it be to implement sha224 ?
Thank you

one thing you could try: execute the build in docker, iirc there already is a docker file ready

then once it is built and everything works you can check the libs inside the docker container and compare them to your ones

Providing my shared lib lineup won't help because it's a different OS release, you meed the default for
what you have. The best way to do that is build a virgin Ubuntu 16.10 or Debian VM and make sure it
works with all defaults. Then apply your mods one at a time until it breaks.

@joblo
I've already tried re-installing libcurl and libssl / libcrypto (different versions) and modify LD_LIBRARY_PATH & LD_RUN_PATH without any results.
I use a chrooted env. because it's easier for modyfing everything but basicaly I have exactly the same isssu on my bare Ubuntu 16.10
I know it's for sure a problem of bad shared library compatibility but i cannot figure out which one are the root cause of the issu.

What are the shared lib. version does cpuminer use?
Can you send me the result of 'ldd cpuminer-opt' in your working system?
It'll be a great help to overcome this issue!

Thank you for your help,
Guillaume

Sorry, been out of the loop for a while.  Any new algo optimizations between 3.8.3.3 and 3.8.4.1?

Looks like some bug fixes, an API feature, and a new algo (yescryptr32).

So far, I don't see anything I would benefit from so far mining on Windows using zergpool, ahashpool, blazepool, and MPH.

The crash appears to be in curl_easy_init so it isn't getting very far. curl_easy_init doesn't take
any input arguments so it isn't a bad pointer passed to it from the application.

Other users have used Debian 9 successfully so there shouldn't be an issue with SW versions. The only thing
I noticed was you used a crhooted environment, I've never used chroot so I don't know if it could
be a contributor.

Since the problem also occurs with cpuminer-multi it points to an issue in your system. Maybe HW,
maybe SW corruption, just guessing. You could try reinstalling curl or try without chroot.

Hello,

I've got issue running it on Debian stretch.
SIGSEGV on an external lib. (libcurl.so.4)

Which releases of Openssl and curl (libcurl / libcurl-gnutls / libcurl-openssl) are you using?
Mine are listed at the end of this thread.

Nb. I've got exactly the same issue trying to run cpuminer-multi from tpruvot

Thank you for your work.

Guillaume
