-- Announcement Thread --


Hi there,
this is the announcement thread for lolMiner 0.9.8lolMiner 1.0 Alpha 2  a multi algorithm Equihash / Beam & Grin miner with focus on AMD GPUs (OpenCL based).
Note it will run on most Nvidia GPUs, too but the speed and stability may vary.


Download:

lolMiner 1.0 Alpha 2:
[Linux & Windows] Click me (1.0 Alpha 2 - May 31st)

lolMiner 0.9.8 stable:
[Linux & Windows] Click me (0.9.8 - Feb 24th)

Driver Requirement:
Windows: Adrenaline 19.1 (pre Navi) / 19.10.02 (Navi), Linux: 18.50 (pre Navi), 19.30 (Navi)


Usage:

The first way to use the miner is from command line interface. The syntax is

Code:
Linux: ./lolMiner --coin <shortCut> --pool <poolAddr>:<portNumber> --user <Wallet or user name> --pass <userPassword>
Windows: lolMiner.exe --coin <shortCut> --pool <poolAddr>:<portNumber> --user <Wallet or user name> --pass <userPassword>
    Here the <shortCut> parameter is a short name for the coin you want to mine. For example inserting GRIN-AT31 will configure the miner to mine Grin with Cuckatoo-31,  BEAM for Beam MW, ZEL for Zelcash and so on.
For more shortcuts and more options please read the lolMiner_manual.pdf shipped with the miner.

About Cuckatoo-32 (Grin)
The primary grin proof of work Cuckatoo 31+ is designed in a way that the original instance - cuckatoo-31 - will fade out beginning mid January 2020, which means its difficulty will increase slowly over a period of 31 weeks until it gets impossible to mine a C31 block on the chain. But as by design also more difficult instances of Cuckatoo, namely Cuckatoo-32 ... Cuckatoo-63 are implemented on the chain that also can make blocks. The difficulties of this higher instances will remain stable, such that at some point it will be more profitable to mine Cuckatoo-32 instead of Cuckatoo-31 (likely from mid of February).

lolMiner 0.8.4 provides the first public implementation on a C32 GPU miner for 8G cards. The code is not yet tuned to the max and thus flagged experimental. When you want to pool mine with it make sure the pool supports Cuckatoo-32. Some pools (e.g. grinmint.com) - especially the pools using the reference pool software - support it on their C31 ports without mentioning it, other pools currently reject C32 shares. Solo mining with C32 will work as usual. Note that a share of C32 has ~2.064 times the weight of a C31 share and will thus rewarded higher / has a higher chance to mine a block by that factor.

Currently there are already two solo mined C32 blocks on the Grin blockchain using an early version of the code published with lolMiner 0.8.4. The two blocks have height 430112 and 430255.

Have fun experimenting with C32.


Version 0.9.3
  • Extended GRIN-AT31 compatibility to older drivers (18.x +)
  • Improved GRIN-AT31 performance on ROCm (RX 470/480/570/580/Vega/VII)
  • Introduced early job cancellation for GRIN-AT31+ (improves hash on pool side, see further release notes)
  • Deeply reworked kernel scheduler
  • Fixed GRIN-AT31 kernel bugs (improving stability and fidelity)
  • Fixed Bug: Vega FE loading 8G instead of 16G GRIN-AT31 solver in Windows
  • Fixed Bug: Watchdog did not call right file in Windows
  • Added --disablewatchdog 1 parameter to disable the 0 sol/s / 0 g/s detection


About Early Job Cancellation for GRIN

The GRIN proof of work is a compute intense and rather slow algorithm. Especially C31 often needs (at 1 g/s) about one second for each graph processed. In case a new job (for a new chain height) arrives, the current calculation effort is worthless, because the block that was mined on already got found.
lolMiner 0.9.3 now introduces an early cancellation for long lasting works: if a new work arrives that invalidates the current run calculations, they get canceled to start quicker on the fresh work. To demonstrate the effect see the example describing the 0.9.2 and 0.9.3 difference:
Assume you have a card running 1 g/s on GRIN-AT31. Then in 2 minutes (120 seconds) it will be able to process 120 graphs. On average - Grin has a 1 minute block time - two of these graphs are already obsolete when they got finished.
lolMiner 0.9.2 will display the 1 g/s, because of 120 processed graphs per 120 seconds. But two of the graphs are then filtered out in the stratum module, thus the pool can see at most 118 / 120 = 0.983 g/s (minus about 1 graph fee).
lolMiner 0.9.3 will cancel the running work before it gets completed. On average you will be able to process one more graph then 0.9.2 assuming both are canceled about half way through. Thus lolMiner 0.9.3 starts 121 graphs and completes 119 of them. The displayed hash rate is now 119 graphs /120 seconds = 0.991 g/s. This equals what the pool could see (minus one for fee), because the 119 completed are the ones that got not canceled early.

Conclusion: lolMiner 0.9.3 DISPLAYED hash rate may be a little lower then 0.9.2, but what arrives at pool is better. The slower the cards are, the more drastic is this effect, e.g. a 580 8G running at 0.65 g/s will benefit almost 2% on pool side, a VII with 1.75 g/s only half a percent.
Combined with the mostly on GPU cycle finder lolMiner achieves a stale share rate of less then 0.7% and thus gives you best displayed to pool hash rate ratio available for Grin Cuckatoo-31.


Version 0.9.2
  • Significant performance improvement of GRIN-AT31 on 8 / 16G cards (+5% on Polaris & Vega, +10 on Navi)
  • Experimental support for GRIN-AT31 and Polaris, Vega and VII using AMD ROCm drivers
  • Added range checks to GRIN-AT31 code (improves better stability)
  • Added function to call external watchdog scripts in case a GPU fails during mining (see release notes)

Usage of Watchdog Script

In case the miner detects no action of a GPU for at least a minute it will call the included scripts "reboot.sh" (Linux) or "reboot.bat" (Windows) and display a warning message in red. Afterwards the counters are reset. The scripts can be used to trigger a reboot of the rig or to call any other watchdog actions. The miner itself will take no further action and continue operation on the remaining cards.


Expected Performance:

  • Radeon VII (stock): 1.79 g/s
  • Radeon VII (1375/975/0.793v, 110W): 1.37 g/s
  • Vega FE (stock): ~1.3 g/s
  • Vega 56 (1230/900/0.85v, 130W): 1.0 g/s
  • RX 5700 (Red Dragon, stock): 0.91 g/s
  • RX 580 8G (1240/2150/0.868V, ~120W): 0.61 g/s

Version 0.9.1
  • Added GRIN-AT31 solver for 16G AMD cards (Better performance on Radeon Vega FE, Radeon VII and Sapphire RX 570 16G)
  • Updated GRIN-AT31 solver for 4G AMD cards (Better performance on Fiji based GPUs, Polaris 10 4G)
  • Fixed a bug causing too low pool hash on GRIN-AT31
  • Added experimental GRIN-AT31 support for AMD Navi (8G), AMD Fiji (4G) and AMD Hawaii (4G / 8G) GPUs

Version 0.9
  • Significant performance improvement for GRIN-AT31 on 8G AMD cards (+22% on Polaris to 30% on Radeon VII)
  • Disabled 16G solver for GRIN-AT31 (the 8G is faster at the moment)
  • Reduced Grin stale shares
  • Added --coin YEC parameter for YCash
  • In command line lolMiner now accepts --pool address:port pattern
  • Fixed a bug with the API crashing when accessed by Chrome based browsers
  • Fixed a bug in EXCC stratum not passing number of submitted shares to the API

Version 0.8.8
- Removed BEAM-I (Beam Hash I), since the fork had happened, BEAM-II and BEAM now both point to the new PoW
- Improved driver detection mechanisms and kernel selection
-> On AMDs: The invalid work group size bug should be gone for Beam*
-> On Nvidias: Performance of Beam Hash II should be improved (since it now uses the right kernels)
- Added new simple .bat (Windows) and .sh (Linux) files for one liner configuration.
- Beta: Equihash 96/5 (--coin MNX) should now allow to change the personalization string (--overwritepersonal=newPers)

(*) Note: If you see now BeamHash II running in a compatibility kernel on Polaris or Vega cards please report me your driver version (it was tested with 19.20 drivers) - older drivers may in future be unsupported for newer kernels.

Changes of 0.8.7 over 0.8.6
- Added support for Beam Hash II on older AMD cards (R 9 200 / 300 4 & 8G cards;  R9 280(X), HD 79x0 with 3G). Note that the auto-switcher is only working with at least 4G, for the 3G cards please use --coin BEAM-II manually on fork height.
- Fixed an issue with Genesis Network (GENX) missing in lolMiner 0.8.x

Changes of 0.8.6 over 0.8.5
- Added support the BEAM hard fork on block 321321 (approx August 15th), read below about the usage
- Fixed a bug with the BEAM stratum back end in case of formatted job descriptions (e.g. new Nicehash platform)

Note about the BEAM hard fork usage
There are now 3 parameters for mining BEAM, --coin BEAM-I, --coin BEAM-II and --coin BEAM
- Use BEAM-I for mining the current / old BEAM proof of work that is valid until the hard fork.
- Use BEAM-II for mining the new BEAM proof of work that is valid from the hard fork.
- Use BEAM for an automatic switcher between the two PoWs. This mode will detect the height and the fork height and will automatically switch over on the right block. Note that this requires the pool to send at least the height. On startup the miner will detect if the pool is compatible to the automatic switcher and display a message if all is fine.
The message is colored in command line:  green - in this case the new PoW is guarantied to be supported; yellow - the height is send so the miner can switch over, but its uncertain if the new PoW is implemented; red - the pool does not send the required information.
In the last case the miner will show the message and then quit after 10 seconds. In this case select the right PoW manually with BEAM-I or BEAM-II.  When at least the height is send, the miner will start mining in automatic mode.


Changes of 0.8.5 over 0.8.4
- Added support for Grin Cuckarood-29 algorithm (--coin GRIN-AD29) for 4G and 8G AMD cards. This new PoW will be active on Grin from block 262.080 (July 17th)

Changes of 0.8.4 over 0.8.3
- Fixed a 0 sol/s issue for Zelcash
- Reduced Zelcash memory usage to 2.9 GBytes
- Fixed a bug with the stratum for 125/4, 144/5, 192/7 and 96/5 in case the pool sends a very low job id.


Changes of 0.8.3 over 0.8.2
- Added a new Cuckatoo-31 solver for 16G AMD cards

Changes of 0.8.2 over 0.8.1
- Added support for ZELHash (EquihashR 125/4/0). The new algorithm is available under --coin ZEL now. If you want to mine Zel pre fork please use 0.8.1 or earlier version

Changes of 0.8.1 over 0.8
- Added support for NiceHash on Grin
- Fixed a bug with some pool software (e.g. grinmint.com)
- Reduced number of stale shares submitted

Changes of 0.8 over 0.7(.1)
- Added support for Grin (Cuckatoo-31) for 4G (Slean) and 8G cards. The parameter is "--coin GRIN-AT31"
- Grin cycle finding is completely done on GPU, the miner has almost 0 CPU load (on AMD, Nvidia has some due to OpenCL back end)
- Stratum bug fixes (NiceHash) for 144/5, 192/7 and  96/5
- Improved general stability
- Added a distinct 1G / 3&4G / 6&8G kernel for mining MNX (Windows, Linux had this in 0.7.1)

Changes of 0.7.1 over 0.7
- Added a distinct 1G / 3&4G / 6&8G kernel for mining MNX
- Added a new parameter --asm. The parameter activates the use of binary kernels, see below.

Binary kernels in 0.7.1
lolMiner 0.7.1 features binary kernels for mining **BEAM** that are tuned with AMD assembler commands. This kernels currently **require** the **AMD ROCm** OpenCL driver in Linux (thats why 0.7.1 is Linux only).
When you run a system with this OpenCL drivers using --asm 1 or the pendant in config file, the miner will try to load the binary kernels.

The kernels feature a speedup of approx 8% on Radeon RX 580 series and 10% on Vega 56, 64 and Radeon VII. Also the energy consumption should slightly be reduced. There are kernels included for RX 470, 480, 570, 580, 590, Vega 56, 64 and Radeon VII. Fiji GPUs can be compatible but are untested yet.

It is planned for future releases to extend the support for other drivers and Windows, but these other drivers make it complicated to handle the improvements. Stay tuned.

Changes of 0.7 over 0.6 stable

- Added support for Beam (BEAM, modified Equihash 150/5), only tuned for AMD cards
- Added TLS support for stratum. The default is off for all coins except Beam but on for Beam. This adds a new parameter --tls to control TLS on / off (see manual on usage)
- Some bugfixes and reworks in the stratum code. It is more stable now
- Complete rework of the mining back end. Lower CPU load for AMD graphic cards.
- GPU sorting changed. Its now sorted by PCIE bus address. This addresses are also shown at startup and in API.
- Integrated all kernel files to the executable
- Lowered fee of ALL algorithms / coins to 1%
- Added --help parameter (needs formating)
- API update interval is now fixed to 10 seconds
- API now smooths the performance data over approx one minute

Coin specific changes:
- Removed workbatch parameter for MNX, its obsolete now
- Removed 96/5 Nvidia specific kernel
- Changed Safecoin (SAFE) from Equihash 144/5 to 192/7
- Added Vidulum (VDL), Equihash 192/7


Changes of 0.6 over 0.5 stable

- New codes for all coins on all cards (better speed)
- New API and statistics module (API updating every 10 seconds)
- Better stratum stability
- Improved stability for many GPU systems
- and many more small stuff I can not remember Wink

I just added the Windows binary  Cheesy

Only thing I observed there is that the API in Windows seems to be a bit unstable - at least the Api shut down from time to time (this does not affect mining itself). I will look into that Smiley

Is there any sense to mine Equihash 144.5 coins on AMD GPUs?
Or this algo is not profitable on AMD GPUs?

speed for Equihash  144,5 is around 10-15 sol  for now is true, need dev tune up.

for Equihash  96,5 (MNX) must be 1000-1100 sol

Is there a way to see the intensity setting and a way to adjust it?
Running miner on 1080ti even with only 50% TPD it is using 250 watts per card..power usage is off the hook.

What options do you search for? Anything specific?

The 10 sol/s for 570 and Equihash 144.5 seem normal (for 96.5 it should be 10k), but the hangup is not - for how long did it mine before crash?

Windows version is not working for me.
The program self opens continually, thousands of times, eating all the computer resources & finally you have to do a hard reset.

Hello,

apart from the few command line options described in the 2 PDF files, are there any other command options? if so, what are they?

Thank you in advance for your answers

What options do you search for? Anything specific?


at least, I would have appreciated the following options (which were present in v0.34):
-max-connection-Attempts
-set-reconnection-timer
-enable-time-print
some options that I will appreciate:
possibility to generate a log file
set maximum temperature threshold
