ethminer defaul GPU usage in Linux?

[arianaa30]

I am running ethminer on my Ubuntu 16.04. The setx commands specified below don't work in Linux, so I just run the ethminer line itself. Wondering what is the default GPU usage I get if I don't set anything?

setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100
ethminer.exe --farm-recheck 200 -G -S eu1.ethermine.org:4444 -FS us1.ethermine.org:4444 -O <My Binance ETH address>.MyRig1

export GPU....=value
example: export GPU_MAX_HEAP_SIZE=100

Yes, I know the Linux equivalents. But if I don't specify them, am I using the 100% of my GPUs?
This is what I get with nvidia-smi:

They are already supplied with ethminer, no need to apply those.

@arianaa30 -- GPU-Util shows 100%, meaning each is being used completely. But your cards are in P2 performance mode. You should use P0 instead. See: http://cryptomining-blog.com/7341-how-to-squeeze-some-extra-performance-mining-ethereum-on-nvidia/

Yes, I am confused on this question. Those settings are only needed in windows. the xset command isn't a tool in Linux because instead, you would just do something like.

export GPU_FORCE_64BIT_PTR=0

I am not a developer for ethminer but I would assume the tool has everything needed to run without these environment settings.

Thanks all for ur information. I can close now.
