burstcoin-jminer v0.4.10 - GPU assisted PoC-Miner (All Platforms)
-
@burstcoinage You need to set the correct platform ID and device ID in the jminer.properties file. But, the batch file does not need to be changed except putting the "pause" command in there like you did. Platform ID and device ID is usually one of these combinations:
0-0
0-1
1-0
1-1

@luxe said in burstcoin-jminer v0.4.5 - GPU assisted PoC-Miner (All Platforms):
you can remove -d64 from start bat, to enable 32bit.
but if your system supports 64bit, install java64bit
http://www.oracle.com/technetwork/java/javase/downloads/jre8-downloads-2133155.html@burstcoinage Also, download the java version that Luxe has circled here. This could be what is preventing you from launching the jminer. I think it will say "Windows x64 (offline)" for the correct 64 bit version, assuming you are running a 64 bit windows.
-
@burstcoinage Maybe add 'pause' to a new line, it is not part of the java call.
Post the error if there is still one.java -jar -d64 -XX:+UseG1GC burstcoin-jminer-0.4.5-RELEASE.jar pause
-
I get the following error, not sure what its means?
I installed both the latest java64 from the link above.
"D:\Burst\F burstcoin-jminer-0.4.5-RELEASE>java -jar -d64 -XX:+UseG1GC burstcoin-jminer-0.4.5-RELEASE.jar
'java' is not recognized as an internal or external command,
operable program or batch file."
-
That is exactly the error I fixed by downloading the correct version of java (not necessarily the newest update of java). I think the version I used is different to the one @luxe presented. Here is my link: http://www.oracle.com/technetwork/java/javase/downloads/jre8-downloads-2133155.html and here is a picture showing which version to choose:
I chose the offline version.
-
@burstcoinage the location of java is not known in command line, try @Propagandalf 's solution, if that does not work, try to add it to the win path variable manually http://www.kingluddite.com/tools/how-do-i-add-java-to-my-windows-path
Another solution would be, to add the path to java.exe like e.g.
"C:\Program Files\Java\jdk1.8.0_92\bin\java.exe" -jar -d64 -XX:+UseG1GC burstcoin-jminer-0.4.5-RELEASE.jar
-
Thanks guys for your help updated and now working. Worked after win 10 popup saying allow java to run so think firewall was preventing the jminer to start. Thought I give heads up if anyone else having similar problem.
-
After much trail and error, I have finally managed to run jminer on a headless linux machine that have 2 GPU's. I tried to change the parameters of the config file, that the miner will use more GPU power (currently only one GPU is used at 13% capacity). Any advice on how to maximized the power of the CPU and GPU combined ? Platform ID and device ID ?
-
@CoinBuster Currently only one openCL device is possible. In most cases GPU is not the bottleneck, so this is not a big issue. Not sure if crossfire linked GPUs are used/show up as one device?! However you could always split up your drives to multiple miner instances and let every single instance use a dedicated device. Also, if there is need for that feature, the code should be adjustable quite simple, never thought about.
Do you currently plan a rig, where you expect 100% GPU load ?! :-)I created a issue on github, will look into it as soon i find some time ...

@luxe I really don't know if the crossfire linked GPUs show up as one device....that's an interesting question. The GPUs on the headless machine work separately, and I need to look into the documentation if it is possible to crossfire them. I have plotted 10TB on the cloud, and I am testing the speeds in which I can read them.
At the moment, I am running a headless machine with 10GB network connection, 16 vCPU 22 RAM and 2 GPU. Reading speeds are good at 100mb/s, but I have reached higher speeds (machine with 32 vCPU, 128 RAM and 10GB connection).The speed was at about 160 Mb/s and all 32 vCPU were maxed to the 100%.
I am trying to reach the read speed limit. Do you have any advice on how to play with the config file to achieve this ?
-
@CoinBuster What read speed limit?! Of your internet connection?! Speeds may be limited by cloud server ... on 10TB i'm quite sure that not GPU/CPU or your System is the bottleneck.
Check this post https://forums.burst-team.us/topic/2411/everybody-post-their-mining-rigs-show-photos/86 i'm just using one 280x ...
-
@luxe Exactly, I want to test this out. I am not sure where is the bottle neck if 32 vCPU went all the 100%while reading the plots. With the GPU assistance they only use 40% and the GPU 13% but I'm sure I can maximize it more to reach much higher reading speeds.
If I ran the same setup and reach the limit at 160mb/s I'll know that this is the cloud provider bottleneck.
-
@CoinBuster Speed provided by your cloud provider may vary depending on his current server load ... so may have nothing to do with jminer at all.
-
@luxe Maybe there was extra load at that time. I have to check again. Is there any chance to change the CPU GPU config with jminer ?
-
@CoinBuster Yes, even i see no big need for it :-) Like i told above, i already created a issue for it, to remind myself ... https://github.com/de-luxe/burstcoin-jminer/issues/27
But could take a week or two.
-
@luxe Thanks buddy I'll sure send some burst in your direction soon. Keep an eye out ;-)
-
@CoinBuster It's more difficult than i thought to add multiple openCL devices with same miner instance ... the code is just not prepared for that, yet. So i fear there will be no quick fix.
-
@luxe Ok. Thanks for looking into that. Is it make sense to you that I mine faster on a VPS with 16vCPU then with a VPS with Nvidia K80 GPU ? it's seems that i have a GPU bottleneck ?
-
@CoinBuster Not sure that Nvidia K80 seams to be a beast ... maybe the openCL drives for it are not very well. Guess must who have such hardware use cuda ... like discussed above, i do not think that cpu or your GPU is bottleneck, have you monitored it?! Is it really on 100% while mining?!
-
I moved my plot files to a NAS and started getting this error:
"ERROR 2304 --- [ readerPool-2] b.j.c.reader.task.ReaderLoadDriveTask : IOException: Bad file descriptor"Any ideas on how to troubleshoot or fix this error?
Thanks in advance!
