Algorithm ExtraLaunchParameters

Algorithm ExtraLaunchParameters

How does it work:

If you are an advanced user that wants to tweak the performance of your GPUs or CPUs you can set supported options in the ExtraLaunchParameters for selected Device and Algorithm.

If you have 3 AMD devices with the following ExtraLaunchParameters settings for algorithm A and B:

• device1 --xintensity 1024 --worksize 64 --gputhreads 2
• device2 --xintensity 512 --worksize 128 --gputhreads 2
• device3 --xintensity 512 --worksize 64 --gputhreads 4

If algorithm A is most profitable for device1 and device2 and algorithm B for device3, NiceHashMiner will run two sgminers for A and B like so:

• sgminer .. --xintensity 1024,512 --worksize 64,128 --gputhreads 2,2 .. (device1 and device2)
• sgminer .. --xintensity 512 --worksize 64 --gputhreads 4 .. (device3)

If algorithm A is most profitable for all three devices, NiceHashMiner will run two sgminers for A like so:

• sgminer .. --xintensity 1024,512,512 --worksize 64,128,64 --gputhreads 2,2,4 .. (device1, device2, device3)

So when setting ExtraLaunchParameters set them per device and algorithm NiceHashMiner will group them accordingly. If you leave ExtraLaunchParameters empty the defaults will be used or ignored if no parameters have been set.
