Title: [ANN] jminer v0.5.3 - GPU assisted PoC-Miner for Burstcoin (BURST) - PoC2 Post by: luxe on September 04, 2015, 06:01:05 PM New java (all platforms) GPU assisted PoC-Miner for Burstcoin (BURST)
PoC - Proof of Capacity Requirements: - Java8 - openCL driver/sdk Features: - POC1 and POC2 supported (both pre- and post-fork @502000) - 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-0.5.3-SNAPSHOT https://github.com/de-luxe/burstcoin-jminer/releases (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. https://i.imgur.com/zSr39cJ.jpg 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) https://i.imgur.com/YYy8EL8.jpg Screenshot of latest SNAPSHOT (the first block is that much faster, cause i mined it 2 times, so data was still in drive caches ...) https://i.imgur.com/JgpumYs.jpg 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.

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?

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? 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.

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 ) 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 I get this and it just hangs so I have to ctrl+c to terminate it.... Code: at burstcoin.jminer.core.reader.data.PlotDrive.<init>(PlotDrive.java:27) Title: Re: [ANN] jminer v0.3.6 - GPU assisted PoC-Miner for Burstcoin (BURST) Post by: luxe on November 10, 2015, 06:59:13 PM 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 Title: Re: [ANN] jminer v0.3.6 - GPU assisted PoC-Miner for Burstcoin (BURST) Post by: Yanakitu Tenatako on December 11, 2015, 10:39:34 PM Hello luxe :)
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 Title: Re: [ANN] jminer v0.3.6 - GPU assisted PoC-Miner for Burstcoin (BURST) Post by: yeponlyone on December 12, 2015, 06:51:16 AM Anyone having problem with running it on 980 ti?

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') Title: Re: [ANN] jminer v0.3.6 - GPU assisted PoC-Miner for Burstcoin (BURST) Post by: Yanakitu Tenatako on December 19, 2015, 12:15:04 AM Hello luxe,

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!

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.

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. 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.

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 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!

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.

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.

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.

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) 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 Title: Re: [ANN] jminer v0.4.2 - GPU assisted PoC-Miner for Burstcoin (BURST) Post by: daWallet on April 02, 2016, 04:18:38 PM 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.

Title: Re: [ANN] jminer v0.4.2 - GPU assisted PoC-Miner for Burstcoin (BURST) Post by: morantis on January 27, 2017, 03:48:43 AM i have a question. i just downloaded jminer for burst coin and the config file is huge. it looks like for pool mining there are only three variables that need to be set. the files reads really odd. there is an explanation for each parameter given in a comment. the way my line breaks are, it looks like the parameter is set right after the comment, but i think that is not the case, as i see the parameters more clearly used later in the file.
the question is this. if i only need to set three parameters in the file, are there other settings in there that are used. can i just make a new config file that contains nothing other than the three parameters and use it or is the included file more important. i know coding and i can read through the file line by line, but would rather avoid that and get it moving more quickly edit:creating my own config file using this method. i started with these three parameters, Code: plotPaths=D:/,C:/,E:/plots,F:/plots Then I started the script and got an info/error saying that a wallet server is not defined. I will set everything one at a time using the errors that the software spits out. I think this is a nice way of seeing each and every piece of info the software uses and better understanding the program. I will post a final config file that was created using this method here for the info of others. Title: Re: [ANN] jminer v0.4.2 - GPU assisted PoC-Miner for Burstcoin (BURST) Post by: morantis on January 27, 2017, 04:19:54 AM until the block chain gets fully synced for me locally and on some other sites i will have no real answer here. I removed the parameters i added for a wallet server because the software claimed to not be able to get mining info. it now works, my dl info is displayed on the pool, but the software is pissed because the mining info is not being reported to it correctly.
once my local wallet is fully recovered from the mess over the past few days, i will point jminer at it for mining info. to test jminer i only used a drive that has 200 GB plotted on it and i am not impressed at the results versus the regular mining software. i saw a dl of a year, and another in the 9 month range. I am using the same pc to plot at this moment, so that could be an issue. once i am locally snyced and i have stopped my current plotting, i will try it for an hour with all my plots and then use uray's for an hour with the same plots and report back here. it seems that the software can and will run with only the three parameters set, setting a walletserver via the config can do nothing but improve things. Title: Re: [ANN] jminer v0.4.2 - GPU assisted PoC-Miner for Burstcoin (BURST) Post by: morantis on January 27, 2017, 01:17:10 PM ok, pretty significant difference. i use s very simple conf file that i will tweak over time.
Code: plotPaths=D:/Burst/plots,C:/Burst/plots,E:/Burst/plots i will go through the original one line at a time and through the github help and see if i can use any other parameters to improve things. but it seems that the gpu miner jminer versus the other cpu miners i have used shows a good 50% or greater increase in production. it is hard to gauge exactly, as this is a new rig, building from the bottom up and i switched to the jminer at the same time that i nearly doubled the plot sizes. but, compared the the same rig that is already running and the time when it had the same amount of plots/sizes there is a big difference Title: Re: [ANN] jminer v0.4.6 - GPU assisted PoC-Miner for Burstcoin (BURST) Post by: luxe on January 27, 2017, 06:45:03 PM @morantis
Sorry if the included jminer.properties leads to this confusion .... i updated OP and added a link to the github wiki page. As far as i can see you did everything correctly ... But to clarify ... nearly all settings have a implemented default value, so there is no need to configure more than you did. The walletServer is only used to get the last winner and not relevant for mining at all. There are some 'hidden' features and fine tuning, it is all described here: https://github.com/de-luxe/burstcoin-jminer/wiki/configure-jminer.properties Just want to mention 'showDriveInfo=true' to see how your single drives perform, may help to optimize your setup. Or 'listPlotFiles=true' (again requires a walletServer) Will list all your plotfiles on startup and show how many blocks they won etc. So nice to see your interest, play arround and ask if something is not clear ... This thread was not very active due to the fact that burst has a very active forum, and most ask questions there (https://forums.burst-team.us).

Download: https://github.com/de-luxe/burstcoin-jminer/releases Notice: burstcoin-jminer-0.5.x supports both, POC1 and POC2 plotfiles. This will also be the case after the fork. However, to handle POC2 pre-fork and POC1 post-fork, twice the amount of data needs to be read and also more CPU and memory resources will be used. The best case for a miner would be, to have converted up to 50% of plotfiles once the fork happens. That would cause the mining setup to behave exactly the same pre and post fork. - Only use one type, POC1 or POC2 on one drive ('plotPath'), mixed will be skipped. - Ensure your POC2 plotfiles do not have staggersize in filename , or they will be treated like POC1. - Read speed is calculated by plotsize, so if jminer reads twice the data on e.g. POC2 pre-fork, the numbers displayed will not be accurate.
