New java (all platforms) GPU assisted PoC-Miner for Burstcoin (BURST)
PoC - Proof of Capacity

Requirements:
- Java8
- openCL driver/sdk

Features:
- solo and all pools supported
- AMD and nVIDIA supported
- Windows, Linux and Mac supported (WARNING: Win7 has strange caching issues on BURST mining!)
- for a QUICKSTART check README.txt

Download:
burstcoin-jminer-0.4.5-RELEASE (0.4.6-SNAPSHOT available)
https://github.com/de-luxe/burstcoin-jminer/releases

Wiki / Setup:
https://github.com/de-luxe/burstcoin-jminer/wiki/configure-jminer.properties

Properties:
https://github.com/de-luxe/burstcoin-jminer/blob/master/jminer.default.properties

To understand the importance, look at the following CPU and I/O usage, 2 Blocks mined with CPU and than 2 Blocks mined with GPU-Support.


In Numbers:

PC-1: 85TB plots:
~80sec with CPU (12 cores intel@4.1GHz) bottleneck: CPU
~16sec with GPU (280x@~50%) bottleneck: HDD read speed

PC-2: 56TB plots:
~70sec with CPU (8 cores amd@4.5GHz) bottleneck: CPU
~24sec with GPU (amd HD 7970@~50%) bottleneck: HDD read speed
~48sec with GPU (amd HD 5450@~100%) bottleneck: GPU

As you can see we have some benefits, finish rounds faster means:
commit all deadlines, even on fast blocks and less hardware usage, save energy!

Here is another screen, take a look a GPU Load (280x@85TB)


Screenshot of latest SNAPSHOT
(the first block is that much faster, cause i mined it 2 times, so data was still in drive caches ...)


About:
I was just for fun developing a own poc miner, i got it working ... but the miner was ~10% slower than e.g. blago miner, therefore i was asking in the community for openCL implementation of SHABAL, to optimize the mining performance ... after @cryo gave me some kernel files from burstDev, i contacted burstDev and he provided the code, that enables this miner to use GPU for mining.
PLEASE DONATE TO HIM:
BurstDev: BURST-QHCJ-9HB5-PTGC-5Q8J9

...

1. The error may occure cause you do not have java8 installed, check version in command line with 'java -version'
 (http://stackoverflow.com/questions/12770622/java-lang-unsupportedclassversionerror)
 This may help you to install java8:
(http://tecadmin.net/install-oracle-java-8-jdk-8-ubuntu-via-ppa/)
2. poolServer=http://pool.com:8125 should be the dev2Pool url
3. platformId and deviceId should be integer values, in general 0 or 1, try just leave it empty ...
on issues with platformId/deviceId check:

Thanks! I'll play around with it some more this weekend. Thanks for getting me on the right track  Cheesy

How does this scale well with APU's?

Is only AMD cards work proper with this or can Nvidia cards too? If the Nvidia cards work, is there performance similar to AMD?

What cards seem to be the best power/performance for the miner?

hi 5 vga 7970 = ?btc/day

nothing without a lot of hdd capacity ... this is still HDD mining ... you could handle/mine ~1PB in below 20sec with that 5x7970 ... if your drives are fast enough.

Miner works with NVIDIA, but i do not have one to test and compare with AMD. (Same for APU)
I just can tell you that a R9 280x can compute/ceck deadlines of ~100TB in below 8sec. (see miner screenshot on OP - the first round)

Hey luxe maybe u can help me out. Trying to use ur miner and can't get it to work properly

I have a AMD R9 270 I'm trying to use as a gpu miner and this is what I have installed

AMD Latest drivers
Java 8 Update 65
AMD AppSDK 3.0
OpenCL 1.1 support for intel core processor family
Running Win7 64bit with 16gigs of ram

Using the gpu plot generator setup option this is what my devices look like

Code:
[0] Intel(R) OpenCL (OpenCL 1.1 )
    [0]        Intel(R) Core(TM) i5-2500K CPU @ 3.30GHz (OpenCL 1.1 (Build 25940.26006))
[1] AMD Accelerated Parallel Processing (OpenCL 2.0 AMD-APP (1800.8))
    [0] Pitcairn (OpenCL 1.2 AMD-APP (1800.8))
    [1]        Intel(R) Core(TM) i5-2500K CPU @ 3.30GHz (OpenCL 1.2 AMD-APP (1800.8))

So in the jminer settings all I did was change the plot path, just 1 drive for testing purposes, my numeric ID, pool and platformId=1
deviceId=0 I'm assuming thats for the 1 AMD then 0 Pitcairn since it's gpu mining

So when I run the batch file with only these settings changed in the visual studio code

Code:
plotPaths=Z:/Burst/plots
poolMining=true
numericAccountId=17908512605713200237
poolServer=http://pool.burstcoin.de:8080
platformId=1
deviceId=0

I get this and it just hangs so I have to ctrl+c to terminate it....

Seams that the miner is not able to successfully scan you plot directory ... whats in there? Only plot files that contain your numeric accountId?

(I saw the whole openCL/GPU setup was correct (@burstcoin thread), so the problem must be somewhere in the plot directory)

Edit:
Ok, we solved that problem, the startnonce used in plotfile was too big for jminer ...
everyone using jminer should currently not use startnonce / nonce 'addresses' (2nd number in plotfile) bigger than:
Long.MAX_VALUE = 9223372036854775807

Hello luxe Smiley

I have an issue running jminer on APU AMD A4-7300.
Java is version 8, win7 64bit, 8 gigs of RAM, latest drivers.

Jminer runs and freeze a computer, after 10-20 seconds, everything looking normal until it blocks it totally.

Last 3 messages in jminer are WARN 4000 unable to get mining info from wallet: null

Anyone having problem with running it on 980 ti? It keeps crashing on me with that GPU, but is stable on, eg, 750 ti and 970.

I have inspected this situation, and noticed that jminer runs well until memory is filled, after no physical memory left it just stall whole thing.

Hi,
You use Win7! There are known caching issues on mining BURST with Win7, that can solved by using another OS! (I also had to use another OS, as i started mining BURST)

About memory usage (beyond Win7 caching issues ...)
The part of the miner that reads the data/plot-files will just read as fast as possible all data into memory.
If your GPU is not fast enough to handle that data, the memory usage will grow (max. 0,025% of your plotfiles + base memory for application ...)

Additional info: https://github.com/de-luxe/burstcoin-jminer/wiki/burstforum.com-thread-recovery (search for 'memory usage')

Hello luxe,

I will add additional GPU to system. I have several cards here laying around. Please advice best for me:

ATI 7790 1Gb ram (bonaire chip)
ATI 5850 1Gb ram
ATI 5870 1Gb ram

Also will change system to linux distribution, is Ubuntu OK and do you suggest some version of it?

Thanks for help.
BTW I support burst, and like it a lot. I'm a believer. Mining with 300Tb.

Just use the most powerful GPU ... to ensure there is no bottleneck ...

Ubuntu should be fine, sry no idea what version is best.
You can also use Win8 or Win10. It is only Win7 with that caching issue.
(I use Win8 and a 280x, my GPU is used 50% while mining 100TB (4TB Drives) @ 15sec per round with a memory usage of 2-4GB)

Thanks for help.

Nice to hear that, we will booost your 300TB :-)

Are this 300TB all attached to same PC? Or do you have multiple PCs running?

I have 9 pcs with 8x4Tb each, plus 2 pcs with 4x4Tb each.





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?

I'm impressed, guess you could save a lot of power, if you manage it to run jminer and attach more drives to less PCs!

Well, i have this case http://geizhals.de/lian-li-pc-d8000b-schwarz-a834927.html (20 drives)
and i added http://geizhals.de/raidsonic-icy-box-ib-545ssk-54105-a817979.html (5 drives) so 25x4TB ...
my motherboard allows 14xSATA and i added two of this controllers: http://geizhals.de/highpoint-rocketraid-2680-a380035.html
I also have some additional none-burst drives attached via USB3+USB3 Hubs ...
You could also use external cases like http://geizhals.de/fantec-qb-x8us3-1461-a669223.html ...
There are many ways to attach a lot of drives to one PC ...

Cooling is no big issue, GPU only runs a few seconds every 4min. ... I just used the case internal 'slots' for air cooling.

But back to you issue ... i asked about you configuration for a reason ... if you have max. 32TB per PC, you should be fine with another OS and one of your mentined GPUs above. Maybe even your embedded GPU will do the job.
