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

[luxe]

Will you please tell me how did you managed 100Tb in single comp, and some more info on cooling system.

Add external usb3 HDDs. You also need some usb3 ports + hubs. You could use your internal HDDs at the same time. I need the win7 installation on my pc, so I'm mining 25 TB on CPU. Jminer won't work on win7 (it'll work, but you can't use the PC for anything else).

Edit: Mining on HDD doesn't need the caching at all, so if this is switched off on all OSs jminer may consume even less power, no?

If you know a way to switch off caching for Win7, feel free to tell us.
In your case of 25TB ... what about adding more memory to your PC?
16-32GB should be able to handle the cache needs?! (not sure if the benefit will be big enough to legitimate such a investion)

I'm with 16 GB RAM. Blago's miner had the same problem with win7 and then he fixed it, so it's doable.

@luxe, it's possible, C <=> Java  (FILE_FLAG_NO_BUFFERING)

Hello,

Today I upgraded win7 to win10, results are good.
JMINER works well, using only few Gb of RAM.
No stress on CPU. I have a feeling that even 4Gb of ram would be ok.

I plotted 6x4Tb drives, read time with GPU and jminer is 52 seconds.
GPU load is high 99%.
So far, so good. Before read time was 1m53s. So, very good result.

Considering adding more HDD drives, jminer is a must have tool.
Great job luxe.

GPU load is really low, from 30%-70%, even lower on hdd read, speed is 120mb/s shown in jminer.
Thinking like there can be better result.

I remember that discussion, my point is still, that i will not implement a Win7 specail case in a java application ...
I hoped for a way, to edit this FILE_FLAG_NO_BUFFERING  in the OS itself, in registry or something ... or via parameter for java vm ...

I am very pleased to hear that ...
You say you need 52sec. thats still a little slow.
Data of a 4TB drive should be read in below 20sec. (my experience, but can depend on sata controller etc.)
If you GPU is not 100% while checking deadlines, the number of drives should not have influence on the 52sec round time.
So basically, if you add another 6x4TB under same conditions, your read speed would be 240mb/s and round would still be finished in 52sec.

Anyway, 120mb/s divided by number of drives is 20mb/s per drive (not cool) ...
If you drives read speed is not limited by hardware, i suggest:
- Use every drive as single drive (no raid or extended partitions over multiple drives or something)
- Use a high staggersize for your plotfiles to reduce seak operations of your harddrive, https://bchain.info/BURST/tools/overlap will provide info about that! Optimize your plotfiles if your staggersize is 8096 or something!

Thank you for post luxe,

I have a problem with win10 and jminer.
Installed everything from scratch and got this error on all machines:

Win 10 Pro 64bit, java latest. Getting same error on every machine.
This occurs really in matter of minutes, sometime after hour or so.


Regarding speed, this is a situation:
Plots of 26Tb are read in less than a minute, 50-60 seconds.

Considering very low-end GPU integrated in APU it is ok for me, GPU usage is on average of 60% (I thought that GPU will be bottleneck - but it is not).
Here are screenshots of GPU usage while mining:

     



I dont know what could cause problem, while I tested it had no issues... never expected this situation.

Exception: java.lang.OutOfMemoryError thrown from the UncaughtExceptionHandler in thread "Timer-1"
Exception in thread "readerPool-52" java.lang.OutOfMemoryError: Java heap space

Java VM is running out of memory (sometimes this happens even if not all system memory is used) ...
you should monitor, if really all available memory of your system is used ...
You can force Java VM to use more memory if not. Your machines have 8GB momory, right?

On memory issues:
1. allow java to allocate more memory e.g.: -Xmx6G will allow java to use up to 6GB of memory, for example:

Code:

java -jar -Xmx6G -XX:+UseG1GC burstcoin-jminer-0.3.6-RELEASE.jar

2. reduce 'chunkPartNonces' in jminer.properties (will only help, if GPU is fast enough, will increase CPU usage)
Maybe try 160000 instead of default 320000.

...
I dont know what could cause problem, while I tested it had no issues... never expected this situation.

If there is a fast block ... so the previous round is not finished, the memory usage may have a little peak.
Maybe you didn't have a fast block while testing ... but I'm quite sure that -Xmx6G will fix your problem.

Well, thats strange, please make sure you use 64bit Java ... test it in command line with:

Code:

java -version

To download Java 64bit JRE (uninstall the 32bit java before installing the 64bit one)
http://www.oracle.com/technetwork/java/javase/downloads/jre8-downloads-2133155.html


Btw. if that was the problem, you will not need that -Xmx6G anymore i guess ...

If it's 64-bits it will say so, otherwise it's 32-bits.

You can try on the command line:

Code:

java -d64 -version

If it's not a 64-bit version, you'll get a message that looks like:

Code:

This Java instance does not support a 64-bit JVM. Please install the desired version.

If not maybe add -d64 as argument to the *.bat, to force 64bit. (if 32bit and 64bit are supported by your java vm, and jminer why ever takes the 32bit one)

Code:

java -jar -d64 -Xmx6G -XX:+UseG1GC burstcoin-jminer-0.3.6-RELEASE.jar

Thats because 1G means the Java VM can only use 1GB of memory, thats to small ... we should focus on running with 64-bit and 6GB :-)
Just to explain, a 32-bit is limited in addressing memory, you noticed that, guess even -Xmx2G did not work.

[Yanakitu Tenatako]

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.

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 )

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

Damn, ok you seam to have some network issues there ... you could try to increase 'connectionTimeout' and 'refreshInterval' make sure your wallet is accessible.

Code:

refreshInterval=3000
connectionTimeout=12000

If that does not help, i need to know more about your setup ... all machines are accessing same wallet or every machine has it's own?
How big is your staggersize?
Please provide complete error logs ... if there was more ... i can not see if the connection problems are resulting from OutOfMemory or the other way round ...

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.

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.

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?
