Wolf's XMR GPU Miner

[lajoie]

Hey Wolf0 - I've been looking through the github source and using that as an example to work through some OpenCL programming. I'm confused by something in the cn0 kernel:

__attribute__((reqd_work_group_size(WORKSIZE, 8, 1)))
__kernel void cn0(__global ulong *input, __global uint4 *Scratchpad, __global ulong *states)
{
...
   Scratchpad += ((get_global_id(0) - get_global_offset(0)));
   states += (25 * (get_global_id(0) - get_global_offset(0)));
...

So, the states pointer is to a buffer of 200 bytes per global threads. Makes sense - each work item offsets the pointer by 25 ulongs (64-bits per ulong or 8 bytes), for a total of 200 bytes per work item.  However, the scratchpad is 2MB per global thread, but the pointer arithmetic just seems to advance it by one uint4 (4 x 4 bytes or 16 bytes).  I would have expected to see something like:

   Scratchpad += (131072 * (get_global_id(0) - get_global_offset(0)));

In other words, each work item should be offset by the full size of the 2MB buffer (131072 unit4's). What am I missing here?

Ah!  That clears it up - thanks Wolf0!

Oh, my HD7950 just about burst into flames! Minimum fan speed is 60% for that old dog. I'm guessing the number of transactions per second has skyrocketed, are we under attack or just really popular?

edit:

I can smell piney resin enamel from the inductor windings vaporizing combined with your classic electrical fire odor. Yeah that puppy just got hot...

edit2:

The RX480 seems to be drawing considerably more than the manufacturers claimed 110W, I can now smell a hint of pine coming from my AX1200 PSU.... The GPU is however chilling.

edit3:

Insane, I had to shut the HD7950 down, the miner's AMD dual core CPU and PSU started bellowing toxic fumes. Both too hot to touch. I feel queezy.  

WTF LOL

I'll try again later after it cools down and smell dissipates with CPU mining DISABLED!!! WOW I CAN"T BELIEVE THAT!!!

Mining XMR is NOT for the faint of heart. Nobody is going to crack cryptonight, ever.

I am trying to improve the performance for CL Kernel and it's calling.
and, I have tried to compile, but I have failed,

can I get an idea about the compiling environments ?

I have tried
    (1) install MinGW
    (2) install All Packages
    (3) compiled and installed jansson-2.8
    (4) copied, AMD_SDK 3.0 x86 (bin/lib/include)
    (5) I have tried to compile using Makefile it can not compile

         it has generate an error : inconsistent operand constranint in an 'asm'

         so, temporary, I have disabled
                    void cryptonight_hash_aesni in cryptonight.c & main.c

    (6) I got so many errors,
         so, I have added
               -lws2_32     

    (7)  But, some error has not been cleared,, Could you give me an advice ?

net.o:net.c:(.text+0x121): undefined reference to `freeaddrinfo'

My 7950 blew a mosfet too, the 4927N. But it was a fault of my own as I had "accidentally" placed the card on the metal frame of my case and switched on the power, and with no black plate, I am guessing that something shorted when the PCB contacts touched the metal frame. My PSU shut itself off, but not quick enough to save the 7950 Ordered a replacement part, taking it to a repair shop to get old one replaced. Hoping for the best.

Apart from the Fan bug, I havent noticed any irregularaties with the mining. Though, one the fan shut down to 0% and I could smell that over heating/ burning smell from one of the 480's that had 0% fan and system rebooted. Everything was well afterwards. Luckily.

Also thanks to Wolf0 and Zanit(?) for sharing the miner and the config. I am mining at around 730 on 480's. With the :-

Threads 2
Rawintensity 504
Worksize 4

Drawing a total watt of around 360W for 3x 480's + system.

If anyone has any other settings please do share.

[icelove]

thanks for sharing.

Oh this miner is so nice.
increase in speed and decrease in power consumption when switching from claymore.
Thanks Wolf0!

Only thing is i get "lowdifficultyshare" on nanopool, i think this might be due to some underclock of core and/or overclock of memory?
threads 2
rawintensity 504
workload 4

Hi,

I have 3 rigs, 2 x 6xRX480-8gb (H97 anniversary, AMD driver 16.9.2 and 16.11.4) and 1 x 2xRX470 (B85M-G43, AMD driver 16.11.4).

With the 2xRX470 rig, the Wolf's miner works fine.
1) with claymore's I have 1380h/s, with wolf's 1425h/s ( Thanks Za1n for config)
2) Power on the wall 330w --> 290w
Thanks Wolf.


All rigs use  Windows 8.1 Embedded Industry Pro, same AMD drivers (tested : 16.9.2 and 16.11.4) but ... same issue with my 2 x 6xRX480-8gb rigs : Error -1 when calling clGetDeviceIDs for number of devices.

I used 6xgpu_mod for 2 x 6xRX480-8gb rigs ( https://lbr.id.lv/6xgpu_mod/6xGPU_mod_download.html)

It very likely has to do with the openCL platform, as the integrated Intel gpu could still be present. is there an option to select another openCL platform?

[Ursul0]

@Wolf0 kudos on the nice miner!
https://bitcointalk.org/index.php?topic=638915.msg17548550#msg17548550

can you maybe add option to select OpenCL platform?
I'd like to run it on my 6*rx4 (including 2*480), but it's anniversary with integrated intel enabled (and genoil does have such switch, that I was using in early ZEC) otherwise there's no cards.

also does anyone know good params for 370?
I'm getting 470+ with:
"threads": 2,
"rawintensity": 380,
"worksize": 10

No clue how to run this miner  start.bat not working, config not working, miner.exe not working, I'm trying to mine Bip coin

[citronick]

wolf -- can i put a failover pool in the same command line? using your latest v0.4/Linux/SimpleMinerOS. Thanks

[manotroll]

How do i use it in linux with suprnova?
How do i use it in linux with dwarfpool?

[Pennywis3]

Wolfie

Do you also have a Windows CPU XMR miner? 

[Reksio34]

Hi,

About   Error -1 when calling clGetDeviceIDs for number of devices issue :

Click Show hidden devices on the View menu in Device Manager and remove the unused gpu drivers (intel HD driver in my case), Reboot.

I did this on 2 rigs and was OK

[ku4eto]

Wolf, is it possible to make the miner more VRAM hungry, and thus chugg out some extra h/s ?
I think i am an exception with 3.6VRAM usage on m R9 290, not really sure how much otherse are using (posisbly, no more than 2-2.5), but there are lots of people with 8GB.

wolf -- can i put a failover pool in the same command line? using your latest v0.4/Linux/SimpleMinerOS. Thanks

Nope, it doesn't manage multiple pools.

Hi wolf - using your miner at "stratum+tcp://cryptonight.usa.nicehash.com:3355" ... I am getting rejects all the time. Is it compatible with Nicehash? Thanks

[Qazo]

can someone help me, I wanted to try wolf0's miner but I never ran it successfully, I set up everything in config file but when I click on  miner.exe it start and turn off immediately
Can you please share your config file for it?
Do I need to delete other algorithms from folder (blake, groestl)?

thank you

Hold Shift + Right click on an empty part of the window inside windows explorer / This PC where your Miner is. Select Open COmmand from here. Type in Miner [name of config file].conf. Or just do a bat file within the folder where you have the miner, and type miner Miner [name of config file].conf hit enter and then pause I.e :-

miner xmr.conf
pause

or

Sgminer xmr.conf
pause

[Qazo]

Ok, now I created bat file and miner start but I get fatal error connecting to pool




I guess something is wrong with config file?


This is my config
{
   "Algorithms":
   [
      {
         "name": "CryptoNight",
         "devices":
         [
            {

               "threads": 1,
               "rawintensity": 640,

            },
            {
               "index": -1,
               "threads": 2,

            }
         ]
      }
   ]
}


can someone share config file for rx480?  i found it at page 12


edit:
for url I set  "url": "stratum+tcp://xmr.suprnova.cc:5222",  and that should be ok now, but now I get new error


I don't have any clue how to solve this

Did you try what a few of the posts above yours suggests to disable the onboard graphics? You can disable onboard graphics either via BIOS or device manager.
