[ANN] jminer v0.5.3 - GPU assisted PoC-Miner for Burstcoin (BURST) - PoC2

[equipoise]

Here's something that may help people on win 7 - Dyncache, a service to manage cache sizes. Something that m$ put out to implement similar cache management for it that they put in win 8+. https://www.microsoft.com/en-us/download/details.aspx?id=9258

Thanks for that hint jaggard!
I have no Win7 for testing, could someone confirm, that this works?
@equipoise, maybe this can fix your issues?

I'll test it first free time possible - most probably next few days. I didn't found it when I searched for a solution. I'll let you know if this fixed it. Thank you for sharing.

I've been using it on my boxen for some time now, mainly because I got tired of the system trying to turn all available ram into cache. It takes a registry value to set the max amount, so it's a bit fiddly to use, but it does help things significantly.

It's not helping. I set the maximum read cash RAM to be 2GB on my 16GB RAM system and I ran it about 24 hours. There may be a bit of improvement in the responsiveness, but it's far from what's needed.

Shame, it worked for me with the blago version with the issue, and helps with many other things here, like copying large amounts of files between drives, so hoped it would apply here also.

Did you test this one: http://forum.burst-team.us:4567/topic/37/runaurufu-s-memory-cleaner-win ... guess all wont work if its the java vm allocation the memory?!

I tried many memory cleaners when I had the same problem with Blago's miner - some of them were reported working by other users in the Burst thread. I even tried different solutions discussed in code forums and wrote and compiled some cleaner solutions on my own. They were not helping back then and I don't think any memory cleaner would help for jminer on win 7 too.

[daWallet]

So the problem in Windows 7 is that the miner stops after ... x hours because of caching/ram issues?

I built a small "jminer -restarter" that restarts the miner after a chosen amount of minutes. I made that because my graphic card is so cheap and slow that after some hours RAM usage runs out of control...  and I use Win 10.

I could release the code for you if that helps... it's nothing special.

burstcoin-jminer-0.4.2-RELEASE
https://github.com/de-luxe/burstcoin-jminer/releases/tag/0.4.2-RELEASE

Changes
- updated used libs (including openCL, use latest drivers!)
- better handling/info on fast blocks
- incorrect size info of plots, GB and TB are decimal, calculation is binary fixed
- eff.read is more likely the average read speed - now we have avg. and eff. speed were eff. is speed since last info shown.
- add optional plot-drive info output
- make memory usage more effective and adjustable (memory usage reduced up to ~50% per default, optimize more by editing 'readerThreads' property)
- write console output to logfile

Setup
jminer is configured in 'jminer.properties' that has to be in same folder.

For a quick start check:
https://github.com/de-luxe/burstcoin-jminer/blob/master/README.md
or README file included in download.

For all available settings check:
https://github.com/de-luxe/burstcoin-jminer/blob/master/jminer.default.properties
or jminer.properties included in download.

NOTICE
There are two binaries for download, please take the one that fits for your OS and OpenCL version.

_{Not sure if this release changes anything for Win7, but it is worth a try.}

burstcoin-jminer-0.4.3-SNAPSHOT

Download:
https://github.com/de-luxe/burstcoin-jminer/releases/tag/0.4.3-SNAPSHOT

I expect the miner to be more stable, and memory usage should be constant now.

Changes:
- bugfixes
- updated versions of used libs (spring+jetty)
- providing some info about used pool on startup (balance, total mined, number of miners)
- add miner and capacity info on commit nonce to pool (e.g. to see miner version+ capacity on burst.ninja)

Please test and report :-)

@equipoise you could try, if the lastest changes have positive effects on memory issues with Win7 ...

This fix didn't help. First 30 minutes there were no problems and it was OK (maybe a little better then 0.3.6, but I'm not sure). Then I was afk about 4 hours and when I came back it had the same problems as 0.3.6.

Sad to hear that, just too bad ... anyway thank you again for giving it a try ... for me the latest snapshot is running for 50+ hours now, without growing memory or other issues ...

[notabeliever]

Works for me in win7 thanks

[luxe]

Works for me in win7 thanks

You are welcome ...

The miner works on Win7, but with more and more TB of plots, the memory Win7 uses for caching is increasing ... thats not the case on Linux/Win8+.
If you say it works for you, some more details like size of your plots and used memory would be helpful.

How are use your miner in servers ? he has integrated video card Matrox G200eW and i do not find opencl driver or sdk for this card.

The main benefit of using jminer, is the use of openCL.
If your hardware does not support openCL, you should consider using another miner.
However, openCL does not necessarily has to run on GPU, there are also CPU drivers available.

The following implementations of OpenCL are currently available:
- The AMD OpenCL driver with support for OpenCL 2.0: AMD OpenCL website (http://support.amd.com/en-us/kb-articles/Pages/OpenCL2-Driver.aspx)
- The NVIDIA drivers with support for OpenCL 1.2: NVIDIA OpenCL website (http://developer.nvidia.com/opencl)
- OpenCL for OSX: Apple OpenCL website (https://developer.apple.com/opencl/)
- Intel OpenCL SDK: Intel OpenCL SDK website. (http://software.intel.com/en-us/articles/intel-opencl-sdk/) [see the Installation Notes (http://jocl.org/IntelInstallationNotes.txt) for using this implementation]

Source: http://jocl.org/

If its not a hardware, but a setup problem (setting correct device and platform) ... instructions can be found e.g. here (thanks cryo):
https://github.com/bhamon/gpuPlotGenerator/blob/master/README.md (check List platforms + List devices)

cutout from jminer.properties (https://github.com/de-luxe/burstcoin-jminer/blob/master/jminer.default.properties):

Code:

# -----------------------------------------------------------------------------------
# - GPU -----------------------------------------------------------------------------
# -----------------------------------------------------------------------------------
# the miner uses openCL for most of the mining calculations, ensure it is setup correctly.
# ...
#
# platformId     - id of openCL platform on your system. one platform may have multiple
# (default:0)      devices, the miner currently uses just one (in general not the bottleneck)
#
# deviceId       - specifies the device used by OCLCecker, can be your first GPU,
# (default:0)      in most cases it will not be 100% used. (depends on capacity)
# -----------------------------------------------------------------------------------
platformId=
deviceId=

Maybe there will be a alternative/fallback 'Checker' without openCL in the future, but thats is not implemented, yet.

However, openCL does not necessarily has to run on GPU, there are also CPU drivers available.
...

Just noticed, that jminer only 'allows' GPU openCL devices, kind of confused, cause i got feedback, that it also works on CPU ... however, next version will allow all available openCL devices.

burstcoin-jminer-0.4.4-SNAPSHOT

Download
https://github.com/de-luxe/burstcoin-jminer/releases/tag/0.4.4-SNAPSHOT
   
Info
Writing logfile is now optional and disabled per default.
Added some additional openCL info/support for easy setup. e.g.:
_{Copied from logs:}

Code:

List of system openCL platforms and devices (* = used for mining)

 * PLATFORM-[0] AMD Accelerated Parallel Processing
                OpenCL 2.0 AMD-APP (1642.5)
 *   DEVICE-[0] Tahiti (2GB) - Advanced Micro Devices, Inc.
                OpenCL 1.2 AMD-APP (1642.5) | '1642.5 (VM)'
                work group size '256', computing units '32', available 'true'
     DEVICE-[1] Intel(R) Core(TM) i7-4930K CPU @ 3.40GHz (17GB) - GenuineIntel
                OpenCL 1.2 AMD-APP (1642.5) | '1642.5 (sse2,avx)'
                work group size '1024', computing units '12', available 'true'

(*) openCL context successfully started! (platformId: 0, deviceId: 0)

Fixed smaller bugs and stuck issue while solo-mining
Added debug mode (will e.g. list incomplete plot-files)

Changes
- support all available openCL devices
- check for openCL support on startup, list available platforms/devices
- prevent wallet from stuck on solo-mining e.g. on slow blocks/no open gui
- writing logfile as optional feature
- stop using jocl 0.2.0 as long as there is no performance improvement
- provide info about 'incomplete' plot-files
- enable selection logLevel DEBUG for users that are interested in more details

I tried for days and I can say that the newest version is very very stable. No memory leaks. I'm using it on Win10.

Great piece of software!
