1.2.4.1 Hotfix

Miner fee reduced by 0.25% while mining on Flockpool.com
Come, check it out and visit our Discord !

Remember that you can reuse the tune_config and config.json
files from version 1.2.X by copying them into the 1.2.4.1 main folder.

Alder Lake (12th gen intel) users are highly recommended to retune the miner.
Make sure E cores number was detected properly!

Fix:

• Fix problem with miner reconnecting after donation to the same pool.
  Occurred if the user switched to the backup pool at least once.
• Fix problem with Large Pages, AVX, or below while tune-full was set to true.
• HOTFIX Fix problem with backup stratum. Could cause miner to not start properly.

General:

• Update startup scripts to accommodate changes in Windows 11.
• Use new avx2-sha-vaes on Alder Lake.
• Correct some output inconsistencies while tuning.

Improvements:

• Add improvements for Alder Lake tuning. ~6% (12900k) increase in hashrate.
  Retuning of the system is REQUIRED to get improved performance.

Flags:

• Add --ecores=N - Specify the number of E cores of the CPU. Miner will try to
  autodetect. It will show the predicted number. Specifying it incorrectly or on the
  platform that does NOT support E cores (Intel Alder Lake) can lead to
  reduced performance.
• Add --disable-rot=LIST - Comma separated list of rotations to not be used
  while mining. For testing purposes only! Using this for normal mining WILL
  reduce your overall average hashrate!! Does not apply to the tuning process.

On newer Linux systems (Ubuntu 22.04+) please use cpuminer-gr-1.2.4.1-x86_64_ubuntu_22.04.tar.gz binaries.

1.2.4

Miner fee reduced by 0.25% while mining on Flockpool.com
Come, check it out and visit our Discord !

Remember that you can reuse the tune_config and config.json

1.2.3

Miner fee reduced by 0.25% while mining on Flockpool.com
Come, check it out and visit our Discord !

Remember that you can reuse the tune_config and config.json
files from version 1.2.X by copying them into the 1.2.3 main folder.

General Changes:

• Disable new rplant protocol by default. Can be enabled with --confirm-block
  Please do not use this flag until rplant fixes their pool!
  rplant is not counting skipped shares on their backend
  towards the users which lead to lower miner payouts/hashrate on the pool.
• Minor output changes.
• Remove some sleeps on Windows release as help and benchmark.log are now
  available for users.
• Add info if the user is trying to use SSL protocol for non-SSL stratum when
  miner is not able to connect to the pool's stratum.
• Warn users if they are possibly using not optimal binaries.
• Make sure Windows .bat file starts proper binaries after the miner crash.
• Build-in stress test.

Flags:

• Add --temp-sensor=PATH - Specify temperature readout file/sensor.
• Add --stress-test - Stress test CPU with 2 fastest rotations.
• Add --confirm-block - Enable miner to send more data if a share is solving
  the block.
  This should provide users with good stress test for their CPU in case
  they want to check basic system stability. Running it for 15 minutes minimum
  should provide basic stability validation. Longer runs are recommended but not
  necessary.

Miner/System crashes:

• Before reporting any cases of crashing / BSOD. Please make sure your CPU
  is fully stable. IF and only IF your system can pass ~20-30 passes of 8GB+
  datasets of Linpack Xtreme, please contact me on discord so we can investigate.
  Linpack Xtreme: https://www.techpowerup.com/download/linpack-xtreme/
• Running miner for 15-30 minutes with "stress-test": true, is also recommended
  to test basic stability of the system.

HiveOS:

For HiveOS binary replacement please check 1.2.2 release notes.
You can reuse 1.2.2 tune_config by running this command
mkdir /hive/miners/cpuminer-opt/gr/1.2.3 ; cp /hive/miners/cpuminer-opt/gr/1.2.2/tune_config /hive/miners/cpuminer-opt/gr/1.2.3/
Adding miner flag "tune-config": "/hive/miners/cpuminer-opt/gr/tune_config"
will save tune config in the same place with each version. This will eliminate
the need for retuning or running the above command.

Binary replacement (zen3, change RYZEN variable to zen2 or zen if needed)
export RYZEN=zen3 && wget https://github.com/WyvernTKC/cpuminer-gr-avx2/releases/download/1.2.3/cpuminer-gr-1.2.3-x86_64_linux.tar.gz && tar xf cpuminer-gr-1.2.3-x86_64_linux.tar.gz && cp cpuminer-gr-1.2.3-x86_64_linux/binaries/* /hive/miners/cpuminer-opt/gr/1.2.3/ && cp cpuminer-gr-1.2.3-x86_64_linux/binaries/cpuminer-avx /hive/miners/cpuminer-opt/gr/1.2.3/cpuminer-aes-avx && cp cpuminer-gr-1.2.3-x86_64_linux/binaries/cpuminer-${RYZEN} /hive/miners/cpuminer-opt/gr/1.2.3/cpuminer-avx2-sha && sed -i 's/LIBCURL3_COMPAT=1/LIBCURL3_COMPAT=0/g' /hive/miners/cpuminer-opt/h-manifest.conf

1.2.2

Miner fee reduced by 0.25% while mining on Flockpool.com

Come, check it out and visit our Discord !

Remember that you can reuse the tune_config file from version 1.2.X by copying it into the 1.2.2 main folder.

Fix:

• Fix problem (introduced in 1.2.1) while staying at one of the dev pools even after the donation period finishes.
  ! Affected only pool. Users were still mining to their wallets !
  It could occur while having connection problems during the donation period was still ongoing
  and during longer connection problems in general.

How to replace 1.1.9/1.2.2 binaries in HiveOS to get the most out of your CPU

You can easily replace binaries in HIveOS with this release in a few simple steps, You can do it by executing remote commands from HiveOS Web UI. For replacement of 1.2.2 binaries, change this cpuminer-opt/gr/1.1.9 to this cpuminer-opt/gr/1.2.2:

1. You need to start 1.1.9/1.2.2 miner at least once.
2. Stop miner
3. Download the current release and unzip it.
   wget https://github.com/WyvernTKC/cpuminer-gr-avx2/releases/download/1.2.2/cpuminer-gr-1.2.2-x86_64_linux.tar.gz && tar xf cpuminer-gr-1.2.2-x86_64_linux.tar.gz
4. Replace binaries used by hive with the ones from this release.
   Replace all default binaries:
   cp cpuminer-gr-1.2.2-x86_64_linux/binaries/* /hive/miners/cpuminer-opt/gr/1.1.9/
   Fix for Hive trying to use incorrect binaries for AVX:
   cp cpuminer-gr-1.2.2-x86_64_linux/binaries/cpuminer-avx /hive/miners/cpuminer-opt/gr/1.1.9/cpuminer-aes-avx
   Ryzen users need to select proper binaries.
   Ryzen Zen/Zen+
   cp cpuminer-gr-1.2.2-x86_64_linux/binaries/cpuminer-zen /hive/miners/cpuminer-opt/gr/1.1.9/cpuminer-avx2-sha
   Ryzen Zen2
   cp cpuminer-gr-1.2.2-x86_64_linux/binaries/cpuminer-zen2 /hive/miners/cpuminer-opt/gr/1.1.9/cpuminer-avx2-sha
   Ryzen Zen3
   cp cpuminer-gr-1.2.2-x86_64_linux/binaries/cpuminer-zen3 /hive/miners/cpuminer-opt/gr/1.1.9/cpuminer-avx2-sha
5. Disable libcurl_compat:
   sed -i 's/LIBCURL3_COMPAT=1/LIBCURL3_COMPAT=0/g' /hive/miners/cpuminer-opt/h-manifest.conf
6. Start miner again. 1.2.x miner needs to be retuned and cannot use 1.1.9 tune_config.

In 1 simple command. Swap RYZEN=zen2 to another binary for different Ryzens like above.
1.1.9
export RYZEN=zen2 && wget https://github.com/WyvernTKC/cpuminer-gr-avx2/releases/download/1.2.2/cpuminer-gr-1.2.2-x86_64_linux.tar.gz && tar xf cpuminer-gr-1.2.2-x86_64_linux.tar.gz && cp cpuminer-gr-1.2.2-x86_64_linux/binaries/* /hive/miners/cpuminer-opt/gr/1.1.9/ && cp cpuminer-gr-1.2.2-x86_64_linux/binaries/cpuminer-avx /hive/miners/cpuminer-opt/gr/1.1.9/cpuminer-aes-avx && cp cpuminer-gr-1.2.2-x86_64_linux/binaries/cpuminer-${RYZEN} /hive/miners/cpuminer-opt/gr/1.1.9/cpuminer-avx2-sha && sed -i 's/LIBCURL3_COMPAT=1/LIBCURL3_COMPAT=0/g' /hive/miners/cpuminer-opt/h-manifest.conf

1.2.2
export RYZEN=zen2 && wget https://github.com/WyvernTKC/cpuminer-gr-avx2/releases/download/1.2.2/cpuminer-gr-1.2.2-x86_64_linux.tar.gz && tar xf cpuminer-gr-1.2.2-x86_64_linux.tar.gz && cp cpuminer-gr-1.2.2-x86_64_linux/binaries/* /hive/miners/cpuminer-opt/gr/1.2.2/ && cp cpuminer-gr-1.2.2-x86_64_linux/binaries/cpuminer-avx /hive/miners/cpuminer-opt/gr/1.2.2/cpuminer-aes-avx && cp cpuminer-gr-1.2.2-x86_64_linux/binaries/cpuminer-${RYZEN} /hive/miners/cpuminer-opt/gr/1.2.2/cpuminer-avx2-sha && sed -i 's/LIBCURL3_COMPAT=1/LIBCURL3_COMPAT=0/g' /hive/miners/cpuminer-opt/h-manifest.conf

1.2.0

Retuning of the miner is required as 1.1.9 tune configs are not compatible!

Miner fee reduced by 0.25% while mining on Flockpool.com

Windows Fixes:

• Fix MSR setup.
• Properly close/stop WinRing0 driver after closing the miner.
• Fix problems with stratum switching while using SSL stratum.
• Compiled binaries should now properly handle multi NUMA configurations.
• Disable QuickEdit on Windows. Prevents the user from accidentally freezing the miner.

General Fixes:

• Fix inaccurate Average hashrate counter that was displayed above each "Periodic Report".
• Fix the problem of "Low difficulty share" in situations where the new block
  is found almost instantly.
• Add Large Pages to different NUMA nodes if some have 0 or not enough memory (Linux).
• Minor fixes.

General Changes:

• Linux binaries system main requirements: libssl-1.1, libcurl-4, glibc-2.16.
• Added autodetect script to the linux and Windows binary packages.
  They should start the best possible binary for the CPU used by the user.
• Added default config.json file that is used to provide flags in one simple place.
• Benchmark provides even more accurate results and takes into consideration
  sub rotations.
• Doing benchmark of the miner now creates benchmark.log file with results.
• Automatically add lost shares to a new entry in "Periodic Report"
  instead of displaying a warning about share mismatch.
• Remove some unused debug output.
• Show progress of the tuning process in percent as well as
  tests_done / tests_total and estimate of time remaining.
• Pass benchmark and tuning speed to the API.
• Provide info about the rotation of the current block and a rough speed estimate.

Algorithm Improvements:

• General optimizations for GhostRider (~0-2% increase).
• New tuning process (up to 15% increase, most noticeable on Intel and Zen/Zen+ CPUs):
  -- Dynamic thread usage - Especially useful for cache starved CPUs like Intels
  and mobile CPUs. Lifts the performance on the more cache-heavy rotations by
  not using some threads while maintaining the best performance on rotations
  not requiring that much cache.
  -- Different prefetch methods - This can bring more performance on CPUs with
  higher overclocks and 2 sticks of RAM while maintaining proper performance
  on CPUs that are underclocked and have 1 stick of RAM.
  -- Tune for 2 sub rotations in each rotation to maximize the performance.
• Update algorithms with improvements from JDD cpuminer-opt 3.18.0

Flags:

• Add --url-backup=URL:PORT - enable backup/failover stratum for the user.
• Add --log=FILE - simple log file of the miner output. Useful on Windows.
• Remove --tune-simple.
• Add missing --no-msr (-y) long flag.
• All flags (like -y --tune-full) are available on all releases but won't
  do anything if they are not compatible. Should provide better universal
  usage and script creation.

Compilation:

• Fix compilation errors on systems with archaic kernels (CentOS 7, Old Fedora & Ubuntu).
• Requires c++20 capable compiler. gcc-10 is recommended. gcc-8 minimum.
• Compilation tested on:
  -- CentOS 7, CentOS 8.4
  -- Fedora 24, Fedora 28, Fedora 34
  -- Ubuntu 16.04, Ubuntu 18.04, Ubuntu 20.04
• Binaries tested on:
  -- CentOS 7 - Requires manual installation of libssl-1.1
  -- CentOS 8.4 - OK
  -- Fedora 24 - Requires manual installation of libssl-1.1
  -- Fedora 28, 34 - OK
  -- Ubuntu 16.04 - Requires manual installation of libssl-1.1
  -- Ubuntu 18.04, 20.04 - OK

HiveOS:

• Fix for AVX cpus on 1.1.9 and possibly 1.2.0:
  cp /hive/miners/cpuminer-opt/gr/1.1.9/cpuminer-avx /hive/miners/cpuminer-opt/gr/1.1.9/cpuminer-aes-avx
  or
  cp /hive/miners/cpuminer-opt/gr/1.2.0/cpuminer-avx /hive/miners/cpuminer-opt/gr/1.2.0/cpuminer-aes-avx
• It is recommended to replace HiveOS binaries with prepared binaries for Ryzen users for best performance.

1. Pick proper zen/zen2/zen3 variant from prepared binaries and replace avx2-sha binary in HiveOS.
2. Disable LIBCURL3_COMP:
   sed -i 's/LIBCURL3_COMPAT=1/LIBCURL3_COMPAT=0/g' /hive/miners/cpuminer-opt/h-manifest.conf

1.1.9

Changes

Fixes:

• Fix miner stop/start with --max-temp flag.
• Revert some changes so the miner is not so memory sensitive. Should be close to how 1.1.7 was.

Improvements:

• Include some VAES optimizations for Cryptonight (~2-4% increase).
• Optimizations for Cryptonight init/finish (~0-2% increase).

Added:

• Add --donation (-d) long flag for use with config files, useful in HiveOS.

1.1.8

We recommend tested pools like r-pool, suprnova, and p2pool.

Changes

Fixes:

• Fix rare cases of Low Difficulty share stream after lost connection.
• Display proper Cryptonight variants used with new blocks.
• Properly calculate real current, min, max, avg hashrate - Hashes done by the miner.
• Block sends of shares with mixed address RTM/WATC/BUTK to the pool.

Changes:

• Check for the --max-temp=N with every submitted share and ~20s. Previously was ~60s and with new block/job.
• Increase the performance of 2 Cryptonight variants and some general Cryptonight changes in GR algo (5-9%). Re-tuning of the miner is recommended!
• Better support for WATC/BUTK mining.
• Provide better info during the tuning process.
• --benchmark - Now provides true average hashrate from each rotation and estimated pool average.
• Dev fee changed from 1% to 1.75%.

Added:

• --force-tune - Forces tuning regardless if the tune_config file is present. Useful on HiveOS.
• --benchmark-old - Old ratios of calculating hashrate. Left for comparison purposes with the previous version.

Removed:

• All algorithms support that is not used by Ghost Rider (GR) algorithm.

Notes:

Ausminers and I have put a great amount of time and work into the miner for this next increase, so we had to up the dev fee % slightly to 1.75% to help offset that time and allow us to work on it more in the future.

1.1.7

Changes

Fixes:

• Fix stratum reconnection problems if users were not able to reconnect within the 60-120s.
• Fix problems with displayed share ping. It could be wrong if some stale shares were skipped. (display only bug)
• Properly detect problems with Large Pages set up on Linux.

Improvements:

• Include tune_config preset files for many CPU models done with the highest possible tuning options. Thanks again to the community for this amazing contribution.
• Detect multiple NUMA nodes on the system and allocate Large Pages to individual nodes.
• Add additional tuning for AVX2+ instruction sets. Users using those binaries are recommended to retune their miner.
• Default AVX2+ tuning is now extended to 80 minutes. Includes additional tests that should bring more performance (6-18%). Includes options that should benefit most of the CPUs. Use --tune-simple for the previous tuning method (34 minutes).
• Stop stratum functionality until miner tunes if tuning is enabled. Should lead to more accurate results.
• --tune-config=FILE It will also now specify a non-default (tune_config) file where the tune configuration will be saved.

Added:

AVX2+ Only!

• --tune-full - 115 minutes. The tuning process tests all possible Cryptonight variants for 4way. Many mobile or low-end CPUs can benefit from it as they are almost always cache starved. It is possible that a longer time from --tune-full will not bring any additional performance!
• --tune-simple - 54 minutes. Previous tuning with included 4way implementations of Cryptonight Turtle and Turtlelite variants.

Build:

• libnuma (libnuma-dev) is now required for building the binaries on Linux.

Notes:

Thanks again to the amazing RTM community for contributing your time and creating configuration preset files for many CPU models that can be used by other users and benchmarking your CPUs!

1.1.6

Changes

Fixes

• Fix dev stratum switch. If dev fee collection is not possible, the dev fee will be skipped.
• Possible fix related to Windows Defender taking an increasing amount of memory if run near the start of the system.

Improvements:

• Tuning available on all instruction sets! Now also improves performance in AVX and non-AES versions of the miner.
• Changed default behavior. Now the miner is tuning by default unless the tune_config file is present or the --no-tune flag is specified.
• --benchmark should provide more real-world performance average that users see on pools.
• Detect problems with stratum connection and stop mining threads until the connection can be reestablished. Until now the miner tried to solve and submit shares even the stratum connection was not established. That could lead to sending many old/stale shares to the pool after successful reconnection.
• Disable MSR functionality on non-AES architectures as it leads to a decrease in performance in those cases.
• Tune Cryptonight prefetch and code.

Removed:

• --cn-config=CONFIG
• --benchmark-config
• --tune - This option is now ON by default.

Added:

• --no-tune - Disable tuning process.
