Release v100.04b1 BETA of bzminer

All feedback is welcome ;)

• New algorithm: KawPow on NVIDIA, AMD and Apple GPUs - Ravencoin, Neurai, Neoxa, Meowcoin and Clore
• -a rvn, xna, neoxa, meowcoin and clore name the coin as they did in bzminer 1.x, and the dev fee is paid on that chain
• One start_kawpow script with a block per coin, instead of one script per coin name
• Pearl is about five times faster on Turing (RTX 20-series, GTX 16-series)
• Pearl's dev fee is now 1%, down from 2%
• Pearl is faster on Ada (RTX 40-series)
• Pearl is faster on 24 GB Ampere cards (RTX 3090, RTX 3080 Ti)
• Pearl draws less power on the rest of Ampere (RTX 30-series)
• Pearl is faster on Blackwell, and now fits 8 GB Blackwell cards
• Xelis is faster on Ampere (RTX 30-series)
• Xelis is faster on CPUs without AVX-512, by about 5%
• Warthog no longer submits duplicate shares around the dev-fee switch
• Shares no longer get stuck on "pending" when the pool changes
• Ergo mines on WoolyPooly again
• Dev-fee connection failures no longer stall the user's pool or count as reconnects
• A dev-fee destination that keeps failing is backed off and dropped, and the fee is still paid in full
• Dev-fee shares stay out of your share table
• An algorithm this build does not have is now an error, and the miner runs in monitoring mode instead of quietly mining something else
• New jobs are logged at info, so the default log shows the pool is still sending work
• Job, difficulty and pool lines all say which algorithm they are for
• Overclocking works on 50-series cards again
• A core clock lock now holds when an offset is applied with it
• cpu_threads governs every CPU thread the miner starts, and they are all pinned
• OpenCL is only loaded if something can use it
• Memory clock locks are checked against the card, and no longer report a lock that landed as failed
• New hotkeys for the memory clock: k/K locks it, m/M offsets it
• New hotkeys for the board power limit: w/W (NVIDIA)
• The tuning hotkeys act on one card at a time, and every screen shows which one
• New tbs column: the real, measured time between shares
• Every mining box now shows block height, difficulty, estimated time between shares and pool latency
• Those four have their own column, a line each, instead of a row apiece under the table (warthog keeps them in the status column)
• [h] is the first hotkey on the row, and pressing it again closes the help
• New hotkey [u]: the pool details - url, wallet, worker and password - press again to hide
• The top rule counts pool reconnects
• The full hotkey legend is on every screen, and h explains each key
• The console draws correctly at any terminal size
• The mouse wheel scrolls again, and text selection still works
• [i]/[I] steps the refresh rate through round numbers
• Log lines say what level they are, and are coloured by it
• The log file holds the device and pool tables, not just the log lines
• New --logfile, and each log file can append, overwrite or timestamp
• The monitor screen has its own log: --monitor-logfile
• The file follows the console's log level live unless logfile_level pins it
• --log-level network shows frames for every algorithm, each exactly once
• Network logs elide long values and binary runs in place instead of dropping the frame
• Xelis records how each card was set up at startup
• New: DRAM timings, on the device page, in the web dashboard and in --ram-info (AMD platforms)
• GPU memory timings are read on Linux too, and cards that cannot report them no longer show a number
• The CPU's arch cell says the architecture, not the core count
• The device page shows more, hides less, and no longer repeats its headings
• Linux shows every GPU sensor the driver publishes, not one of each kind
• CPU fans are detected on Linux boards the kernel has no sensor driver for
• The web API carries height, share_work and the reconnect count, and /status fills in block
• Quieter logs: kernel and prover internals are off unless you pass --internal-log
• Fixed: per-thread CPU usage read 0% on Linux
• Fixed: AMD CPUs reported temperatures for CCDs that are not fitted
• Fixed: the share log kept naming the CPU thread count from startup after [t] had changed it

Mines Ergo, Ravencoin, Neurai, Neoxa, Meowcoin, Clore, Pearl, VERUS, Warthog and XELIS, and ships sha256d as the open-source SDK example.

Downloads

Verify before running:

# Linux / macOS
sha256sum -c <<< "<hash>  <file>"

# Windows (PowerShell)
Get-FileHash .\<file> -Algorithm SHA256

A checksum only proves the file is the one that was published — always download from the official release page.

Getting started

1. Unpack the archive for your platform.
2. Open a start_<algo> script and replace the placeholder wallet with your own.
3. Run it, then open http://127.0.0.1:4014/ for the dashboard.

readme.txt inside each archive has the full quick start, the common options, and the hardware-safety settings. config.txt is a commented copy of every setting, generated from the shipped binary, so it always matches the build you have.

Updating on a mining OS

Both fetch this exact version, so they can be pasted as-is - the version below is already the one on this page.

MMPOS

Put this in miner profile → advanced → "Initiate command prior to miner launch". It downloads once; on every later launch the if sees the archive already in /tmp and exits immediately, so it costs nothing per restart.

export version="v100.04b1"
if [ -f "/tmp/bzminer_${version}_linux.tar.gz" ]; then
exit 0
else
cd /tmp; wget https://github.com/bzminer/bzminer/releases/download/${version}/bzminer_${version}_linux.tar.gz; tar -xvf bzminer_${version}_linux.tar.gz; sudo cp -adpR bzminer_${version}_linux/bzminer /opt/mmp/miners/bzminer/
fi

Hive OS

Run it over SSH or in the Hive web shell.

You do not need to know which bzminer version is installed. Hive keeps one folder per version under /hive/miners/bzminer/, and the flight sheet decides which one runs - so this replaces the binary in every bzminer folder it finds and whichever one your flight sheet points at gets the new build. That is the whole reason it does not name a version directory.

version=v100.04b1
cd /tmp && wget -q https://github.com/bzminer/bzminer/releases/download/${version}/bzminer_${version}_linux.tar.gz && tar -xf bzminer_${version}_linux.tar.gz || { echo "download failed"; exit 1; }
miner stop
n=0; for d in /hive/miners/bzminer/*/; do [ -d "$d" ] && cp -f "bzminer_${version}_linux/bzminer" "$d" && n=$((n+1)); done
[ "$n" -gt 0 ] && echo "updated $n bzminer folder(s)" || echo "no /hive/miners/bzminer/<version>/ found - install bzminer from the flight sheet first"
miner start

It prints how many folders it updated. 0 means bzminer has never been installed from a flight sheet on that rig, so there is nothing to replace yet.

Algorithms in this build

Reporting problems

Please include: your OS, GPU model(s) and driver version, the algorithm and pool, and the first ~40 lines of the log (it prints the build, the devices it found, and what each backend reported). --list-metrics output helps for sensor issues.
