did you know the processor type on it , maybe its another type of if so you need to change the parameters
CFLAGS="-O3 -march=btver1 -Wall" CXXFLAGS="$CFLAGS -std=gnu++11" ./configure --with-curl
read also the release-note included in the Miner
please provide more info , OS , Hardware that will increase your chance to get help
Well strange is that cpuminer-multi is running without any problems.. Going to ask vps provider what cpu is it running. CFLAGS="-O3 -march=btver1 -Wall" CXXFLAGS="$CFLAGS -std=gnu++11" ./configure --with-curl

cpuminer-opt 3.6.1 is released and available for download.
It fixes a data alignment issue in Lyra2Rev2 and also adds support for HW accelerated SHA
encryption and decryption available on Ryzen CPUs. No mainstream intel CPUs with SHA
are exepected until Cannonlake.
SHA256 is used by the following algos and should benefit from HW acceleration:
sha256t, lbry, skein, myr-groestl, m7m.
In order to make use of SHA several requirements must be met. It may require
installation of packages newer than available in the distribution as SHA
support is still very new.
Windows binaries are not avaialable and I have not yet investigated compiling
with SHA support on Windows.
Requirements:
Ryzen CPU
Recent Linux distribution
Compiler version with support for sha
Openssl development package with support for sha
Cpuminer-opt source code with support for sha
This is more of a what-to than a how-to, users should already know how.
1. Confirm CPU has SHA support availble and enabled
2. Confirm compiler has support for SHA (gcc 5+).
3. Confirm openssl has support for SHA.
https://github.com/openssl/openssl/commit/619b94667cc7a097f6d1e2123c4f4c2c85afb8f7
4. Configure with arch that includes sha or manually add "-msha" to CFLAGS.
5. Compile.
Recommended test plan:
SHA support in cpuminer-opt is untested therefore problems are likely. Please include all relevant
information, including compiler and openssl versions, when reporting problems.
In addition to SHA, Ryzen is the first AMD CPU to include AVX2. Before attempting to use SHA it would
be useful to determine a baseline configuration for this architecture. Does "-march=core-avx2" provide
an optimum build for Ryzen?
Use the best build as a baseline for comparison with SHA acceleration.
Choose one or more algos that use sha256 (listed above) and obtain baseline performance data.
Rebuild with SHA support. Does the compiler recognize "-march=ryzen" and does it include sha?
Otherwise add "-msha" to the baseline configuration.
Compare performance and report.

In the version (for example) 3.6.1 There will be enhancements for ryzen amd cpu? .
Yes.

Lyra2REv2 AVX2 works on Windows with 3.5.13 and it might be a little faster than 3.5.12.
Can you give us a link on 3.5.13 please? I was unable to find it, even in google cache. Will be really helpful if u share binaries w/o removing the previous links, if possible
3.6.1 will be released soon, I found the bug in lyra2v2.

Wave, person,
Would anyone have a tutorial on how to use download, compile and use this miner in UBuntu?

Seems that lyra2rev2 is broken in 3.6.0 avx2 build. When I launch the miner, cli doesn't show cpu threads at all, then miner quits after ~15 seconds. It's OK on 3.5.12 avx2 with same settings:

You're right, crashes on Windows, but works on Linux. I need to investigate.
Edit:
Lyra2REv2 AVX2 works on Windows with 3.5.13 and it might be a little faster than 3.5.12.
There are no changes to the Lyra2 code between 3.5.13 and 3.6.0 so I don't have any clues.
It's going to take a while to figure this out.

It's OK with 3.6.0 avx and other versions thought (slower, of course). Hope that info helps.

Wave, person,
Would anyone have a tutorial on how to use download, compile and use this miner in UBuntu?

Looking for Ryzen owners to test SHA acceleration.
Ryzen CPUs have HW accelerated SHA, something Intel's mainstream CPUs won't have until Cannonlake.
Requirements:
Ryzen CPU
Linux
Compiler version with support for sha
Openssl development package with support for sha
Cpuminer-opt source code with support for sha
I can provide the last one. GCC is supposed to have support for -msha starting in v 5, and Openssl added support in 2014
so both should be available in Ubuntu 16.04.
The following algos use sha256 and should benefit from HW acceleration: sha256t, lbry, skein, myr-groestl, m7m.
