burstcoin-jminer v0.4.10 - GPU assisted PoC-Miner (All Platforms)

Thanks @Blago for helping out, while i was sleeping :-)
@tradz Just give it a try, both miners have their strenghts ... feel free to ask if you have a issue.
jocl.org is just the java lib used by jminer, it is not the openCL driver itself, but on that page they link to the drivers of different manufacturers.OpenCL support is included in the latest NVIDIA GPU drivers, available at www.nvidia.com/drivers
source: https://developer.nvidia.com/opencl
So you may not need to install additional software to use OpenCl.
-
@Blago I thank you as well Blago! This was or is very helpful. Now I have a better understanding ;) Blagone!!!
I will report back here if I run into issues...
-
@luxe Nice to be writing with the MAN! Thank you as well for responding to my needs and in a timely manner@that. So, you think I should try to do things without downloading drivers, as you mentioned it's already included in my system?
-
@tradz Trying does not hurt :-P If you start the miner and drivers are missing, the miner will tell you ....
-
@luxe Right! lol I decided to switch to the J-Miner come time the 30th a couple days before the next month starts so that I can start a fresh new month with better results. Blago is doing it's job for now, I can't complain!
-
@luxe Awesome! Thank you luxe!
Using memory more than low. So I can load plot data from all HDDs at once!

Hi!
I just bought a new pc and now jminer won't work.

@umutusu said in burstcoin-jminer v0.4.6 - GPU assisted PoC-Miner (All Platforms):
[nvopencl.dll+0x3870cd]
Its openCL error, I downgraded nvidia driver and it worked with me. Maybe @luxe can be of more help here
-
@umutusu
log file unavable.
new pc with the same GPU or new?
-
@rnahlawi current jminer version uses latest jocl.org lib for openCL, thats all i can do/say ... glad you got it running ... jminer will be updated as soon as new version of jocl.org is available.
@umutusu sry currenly have no concrete idea ... please try to google for
EXCEPTION_ACCESS_VIOLATION (0xc0000005)i found some explanations but nothing concrete.

burstcoin-jminer-0.4.7-SNAPSHOT
Download:
https://github.com/de-luxe/burstcoin-jminer/releases
Updates:
- prevent reading optimized plotfiles in too much parts, if no useful number can be calculated due chunkPartNonces setting.
Details:
A optimized plotfile is handled in multiple parts by jminer, the calculation of the number of parts could lead to very high number due not perfect algo (i have to think about). Very high number of parts causes a drive/miner to be slow as hell.
As quick fix i added a fallback that takes 8 parts if number of parts is bigger than 100.Edit: I run into the above issue after plotting with Xplotter auto all remaining space of a drive ... what leads to staggersize i never had before, so if someone had a slowed down jminer after plotting in the same way, check new version.
Just to be clear, there is no issue with Xplotter, it is just awesome.

@Blago: https://www.sendspace.com/file/p39ll8 here it is
everything new (msi gtx 1080)@luxe: I tried with stable version 0.4.5 and snapshot 0.4.6. i'll try with snapshot 0.4.7 and also take a look at for that
EXCEPTION_ACCESS_VIOLATION (0xc0000005)@rnahlawi : i'l try that.
-
@Blago
did you see the log file?
@luxe
with 0.4.7 it's the same error.
And I can't seem to find any comprehensible explanation (at last I don't understand) forEXCEPTION_ACCESS_VIOLATION (0xc0000005)I even install visual studio and Cuda SDK (apart from Nvidia driver which normally contains OpenCL driver)
@rnahlawi which version of Nvidia driver is you currently use? I searched for[nvopencl.dll+0x3870cd]but I don't understand that either.
-
@umutusu Sorry the log tells me nothing, i can only suggest this ... check if gpuPlotGenerator works for you:
https://github.com/bhamon/gpuPlotGenerator/releases
https://github.com/bhamon/gpuPlotGenerator#setup-1
That would indicate that openCl drivers are fine. And it is only a jminer issue
(i do noit think so)
If gpuPlotGenerator also does not run, you should try to deinstall all gpu drivers and stuff completely (not sure with nvidea, for amd there is a tool to cleanup). restart your system and reinstall lastest nvidea driver only (should include openCL).
-
@luxe I created my plots yesterday with XPlotter to have optimized plots.I really don't want to wait again 36hours :)
I downgraded nvidia drivers to previous version and I have no more this issue but now I have CL_OUT_OF_RESOURCES.
I think the latest nvidia drivers have a problem or it's a opencl 1.2 issue with gtx 1080.
Do you know how to resolve this CL_OUT_OF_RESOURCES issue?
Thank you again
-
@umutusu Ok, you got me wrong ... i didn't want you to re-plot ... just to check if it works, as it is also openCL based. But if openCl context starts up now, please provide a image of jminer log ... are you sure you configured the platformId/deviceId correctly? is your gpu marked(*) on jminer startup?

@luxe How embarrassing :/
It was actually my bad.
GPUplot generator worked once I made the setup and realized that I used old device and platform id without thinking that is a new PC.
Thanks and sorry for bothering you
-
@umutusu No problem, glad we could solve that :-)
-
a side note: latest Nvidia drivers doesn't work!
I just updated again to latest drivers and the same issue (fatal error etc)
I rolled back to the earlier driver and voilĂ , it works again!
so it's a Nvidia driver issue
-
@umutusu i also had problems with latest amd drivers few weeks ago, since than i do not update anymore :-) also may be caused by the jocl.org lib. if the jocl.org lib does not work with latest drivers, they will sure provide a update ... just a question of time ...
