Topic: [ANN] jminer v0.5.3 - GPU assisted PoC-Miner for Burstcoin (BURST) - PoC2 - page 2. (Read 23323 times)

Thanks, looking forward to that ... even i'm not very optimistic, there have been some big improvements in memory usage and maybe that changes something.

OK. Thank you. I'll test in a few days and I'll let you know.

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 ...

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

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.

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.

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?!

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.

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.

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.

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.

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

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

This error does not effect your mining ... but indicates you have duplicate or overlapping plots.
Please check for plot-file duplicate or overlapping plots e.g. use https://bchain.info/BURST/tools/overlap

jminer uses a lookup with chunkPartStartNonce as unique key, to calculate how much capacity is left in a round.
Once a chunkPart is read it's removed from that lookup ... in your case it was already removed, means you have at least two times the same chunkPartStartNonce.

Hi luxe,

Thanks for your work   Since some time, I get this error:

Error: ReaderPartLoadedEvent for unknown chunkPartStartNonce

No java error, just that on two boxes. And hundreds of them. No errors with blago's miner, but strange thing is that they seem to find the same number of dl. I do use large startnonces....

Any idea....? No hits on google.

I am really sorry for bothering, but I am getting this error on every couple of hours:
I tried with memory options 6G 4G and without and still, it is the same.

I'm glad we could solve that issue ... let it burst :-)

It is now OK. Really sorry for this, I checked again and I DL-ed 64bit installer. Anyone should pay attention to what this java automatic installer is doing by own will.


First result is here : (looks really gooooood )

Going to fix right away.
But I am certain I installed 64bit version, I always do.
De facto, it is not then 64bit.

Update in 5 minutes.

Thank you again, Luxe.
