Note2: It is not recommended to mine using a laptop.

## Supported Cuda architecture

* Maxwell GTX 900 series, Quadro M series, GTX Titan X
* Pascal GTX 1000 series, Titan Xp, Tesla P40, Tesla P4,GP100/Tesla P100 DGX-1
* Volta GTX 1100 series (GV104), Tesla V100
* Turing GTX 2000 series (GTX RTX, GTX 2060, GTX 2070, GTX 2080)

## Gpu mining
To mine using gpu you must provide the gpu numbers and the amount of threads for each gpu.<br>
If you only have one gpu, use **-gpu 0** and **-gputhreads {amount of threads}**<br>
If you have more than one gpus, you can see their number by executing the miner with the *list* option :<br>

rhminer v0.9 beta for CPU and NVIDIA GPUs by polyminer1 (http://github.com/polyminer1)
NVIDIA CUDA SDK 9.2
Donations : Pascal account 529692-23
Donations : Bitcoin address 19GfXGpRJfwcHPx2Nf8wHgMps8Eat1o4Jp
List of gpus and cpus:
GPU0 : GeForce GTX 1060 3GB
GPU1 : GeForce GTX 1060 3GB
GPU2 : GeForce GTX 950 2GB
CPU : Intel(R) Core(TM) i5-4460 CPU @ 3.20GHz
```
Then select the ones you want to mine with like this : <br>
```
rhminer -s http://localhost:4009 -gpu 1,2 -gputhreads 262,102
```

## Ideal CUDA threads count
To find the ideal maximum amount of threads, start with 75% of the memory divided by 8.8. <br>
For a GTX 1060 3GB that is 3000 * 0.75 / 8.8 = 255 threads. <br>
Then run 2 minutes and if everything is stable, raise by say 32 until you get no crashes after 2 min.<br>
To help you in that process, look for the log line that say "CUDA: Using " when the miner starts. It will indicate how much memory you take and how much is left depending on your selected thread count.<br>
**ALLWAYS** let at lease 150 meg of free memory, for internal OS operations, or you have stability issues.<br>


## Tested on
CPU: I3, I5, Core2, Xeon, Athlon <br>
GPU: GTX 950, GTX 1060, GTX 1070 <br>
CUDA: Linux CUDA 9.1, Windows CUDA 9.2 <br>

## Stability issues
Thre are some limitations on nvidia gpu to consider.

First, the kernel is not 100% stable in all settings. This mean you'll have to experiment to find the stable sweet spot in term of gputhreads. Maximum thread count does not mean maximum speed. Sometimes lower thread count will give you more stability and more speed also.

On multiple gpu rigs, it's NOT recommended to mine CPU at the same time. You'll have more kernel timeout error because the driver will lack cpu time.<br>
Also, it is recommented, on multiple GPU rigs, to run the miner in a loop in a batch file !

## Troubleshoot
On Windows 7/8/10, if you get the missing OpenCL.dll error you need to download it into rhminer's folder. (hint: You can safely get one with the Intel SDK on Intel's opencl website)

-cputhreads Number of CPU miner threads when mining with CPU. ex: -cpu -cputhreads 4.
NOTE: adding + before thread count will disable the maximum thread count safety of one thread per core/hyperthread.
Use this option at your own risk.
-gpu Enable indiviaual GPU by their index. GPU not in the list will be disabled. ex: -gpu 0,3,4.
-gputhreads Cuda thread count. ex: -gputhreads 100 launche 100 threads on selected gpu
-kernelactivewaiting Enable active waiting on kernel run.
This will raise cpu usage but bring more stability, specially when mining on multiple gpu.
