Low speed with GTX1070

[Coinpiet]

Hello i have a mining rig with 3 GTX 1070 and 3 nvidia P104
i compiled code with cuda 10.0

here is my command with 1 card

Kangaroo.exe -t 0 -g 128,256 -gpu -gpuId 1 in.txt

my question is why is it so slow when you get with 1 GTX 1050TI 125 Mkeys per card ?

[JeanLucPons]

try remove cpu thread with -t 0

[JeanLucPons]

The creation of kangaroos is quite slow.
You cpu seems overloaded.

[Coinpiet]

same result with -t 0

[Coinpiet]

i have celeron G3930 2.9 Ghz cpu for my mining rig

[virus-cyber]

Kangaroo.exe -t 0 -g 28,512 -gpu -gpuId 0 in.txt

[virus-cyber]

everyone wants someone else’s bitkonts but no one wants to think

[Coinpiet]

same result only get 10 mkeys

[virus-cyber]

Kangaroo.exe -t 0 -d 12 -g 28,512 -gpu -gpuId 0 in.txt

[JeanLucPons]

If you have compiled by yourself, did you compile as Release version and not Debug.
Debug will be terribly slow.
Creation of 2^20 kangaroos should take 2 ou 3 sec max.

[Coinpiet]

ok i download from release and and run Kangaroo.sln in visual studio
and in Debug folder i get the Kangaroo exe

[Coinpiet]

ok i get it now i get 260 Mkeys per card

[Shadow145-cpu]

@Coinpiet > ok i get it now i get 260 Mkeys per card

How did you fix your speed problem?

Problem solved, I compiled for release and it's OK.
