cpuminer-opt is a console program run from the command line using the
keyboard, not the mouse.
See also README.md for list of supported algorithms,
Security warning
----------------
Miner programs are often flagged as malware by antivirus programs. This is
usually a false positive, they are flagged simply because they are
cryptocurrency miners. However, some malware masquerading as a miner has
been spread using the cover that miners are known to be subject to false
positives ans users will dismiss the AV alert. Always be on alert.
The source code of cpuminer-opt is open for anyone to inspect.
If you don't trust the software don't download it.
The cryptographic hashing code has been taken from trusted sources but has been
modified for speed at the expense of accepted security practices. This
code should not be imported into applications where secure cryptography is
required.
Compile Instructions
--------------------
See INSTALL_LINUX or INSTALL_WINDOWS for compile instruuctions
Requirements
------------
Intel Core2 or newer, or AMD Steamroller or newer CPU. ARM CPUs are not
supported.
64 bit Linux or Windows operating system. Apple, Android and Raspberry Pi
are not supported. FreeBSD YMMV.
Reporting bugs
--------------
Bugs can be reported by sending am email to [email protected] or opening
an issue in git: https://github.com/JayDDee/cpuminer-opt/issues
Please include the following information:
1. CPU model, operating system, cpuminer-opt version (must be latest),
binary file for Windows, changes to default build procedure for Linux.
2. Exact command line (except user and pw) and intial output showing
the above requested info.
3. Additional program output showing any error messages or other
pertinent data.
4. A clear description of the problem including history, scope,
persistence or intermittance, and reproduceability.
In simpler terms:
What is it doing?
What should it be doing instead?
Did it work in a previous release?
Does it happen for all algos? All pools? All options? Solo?
Does it happen all the time?
If not what makes it happen or not happen?

v3.15.0
Fugue optimized with AES, improves many sha3 algos.
Minotaur algo optimized for all architectures.
Fixed neoscrypt BUG log.
v3.14.3
#265: more mutex changes to reduce blocking with high thread count.
#267: fixed hodl algo potential memory alignment issue,

log outout.

low difficulty shares.
v3.12.0

API can now be enabled with "-b port" or "--api-bind port".
It will use the default address 127.0.0.1.
Editorial: Short form options should only be used on the command line to save
typing. Configuration files and scripts should always use the long form
"--api-bind addr:port" without relying on any defaults. This is a general
recommendation that applies to all options for any application.

Summary log report will be generated on stratum diff change or after 5 minutes,
whichever comes first, to prevent incorrect data in the report.
Removed phi2-lux alias (introduced in v3.9.8) due to Luxcoin's planned fork
to a new algo. The new Luxcoin algo is not supported by cpuminer-opt.
Until the fork Luxcoin can be mined using phi2 algo.
--hide-diff option is deprecated and has no effect. It will be removed in a
future release.

use the long option.
New options:
-N, --param-n: set the N parameter for yescrypt, yespower or scrypt algos
-R, --param-r: set the R parameter for yescrypt or yespower algos, scrypt is
hardcoded with R=1
-K, --param-key: set the client key/pers parameter for yescrypt/yespower algos.
These options can be used to mine yescrypt or yespower variations using
the generic yescrypt or yespower algo name and specifying the parameters
manually. They can even be used to mine variations that aren't formally
supported by a unique algo name. Existing algos can continue to to be mined
using their original name without parameters.
v3.9.6.2
New algo blake2b.
Faster myr-gr on Ryzen using SHA.

yellow is only used to report abnormal activity.
Changed stats colours, yellow now means below average, white is average
range. Tweaked colour thresholds.
Changed colour of stratum difficulty change messages to blue to match other
normal protocol messages. Blue messages (block, stratum, submit) will no
longer be displayed when using -q option.
Added job id to new block, share submit, and share result messages and added
new nessage when a new job is received for an existing block. This will for
better troubleshooting of invalid job id rejects seen at zergpool.
Some more restructuring.

based on share difficulty, network latency, 5 minute summary.

Faster skein2 with 4way AVX2 enabled.

Ongoing restructuring.
v3.9.3.1
Skipped v3.9.3 due to misidentification of v3.9.2.5 as v3.9.3.
Fixed x16r algo 25% invalid share reject rate. The bug may have also
affected other algos.

on Ryzen.

Lyra2z now hashes 8-way on CPUs with AVX2.
Lyra2 (all including phi2) now runs optimized code with SSE2.
v3.9.1.1
Fixed lyra2v3 AVX and below.
Compiling on Windows using Cygwin now works. Simply use "./build.sh"
just like on Linux. It isn't portable therefore the binaries package will
continue to use the existing procedure.
The Cygwin procedure will be documented in more detail later and will
include a list of packages that need to be installed.
v3.9.1
Fixed AVX2 version of anime algo.
Added sonoa algo.
Added "-DRYZEN_" compile option for Ryzen to override 4-way hashing when algo
contains sha256 and use SHA instead. This is due to a combination of
the introduction of HW SHA support combined with the poor performance
of AVX2 on Ryzen. The Windows binaries package replaces cpuminer-avx2-sha
with cpuminer-zen compiled with the override. Refer to the build instructions
for more information.
Ongoing restructuring to streamline the process, reduce latency,
reduce memory usage and unnecessary copying of data. Most of these
will not result in a notoceably higher reported hashrate as the
change simply reduces the time wasted that wasn't factored into the
hash rate reported by the miner. In short, less dead time resulting in
a higher net hashrate.
One of these measures to reduce latency also results in an enhanced
share submission message including the share number*, the CPU thread,
and the vector lane that found the solution. The time difference between
the share submission and acceptance (or rejection) response indicates
network ltatency. One other effect of this change is a reduction in hash
meter messages because the scan function no longer exits when a share is
found. Scan cycles will go longer and submit multiple shares per cycle.
*the share number is antcipated and includes both accepted and rejected
shares. Because the share is antipated and not synchronized it may be
incorrect in time of very rapid share submission. Under most conditions
it should be easy to match the submission with the corresponding response.
Removed "-DUSE_SPH_SHA" option, all users should have a recent version of
openssl installed: v1.0.2 (Ubuntu 16.04) or better. Ryzen SHA requires
v1.1.0 or better. Ryzen SHA is not used when hashing multi-way parallel.
Ryzen SHA is available in the Windows binaries release package.
Improved compile instructions, now in seperate files: INSTALL_LINUX and
INSTALL_WINDOWS. The Windows instructions are used to build the binaries
release package. It's built on a Linux system either running as a virtual
machine or a seperate computer. At this time there is no known way to
build natively on a Windows system.
