Can't mine and can't compile too much errors

[mrschaeffer2018]

Hi, can you guys create a cuda 9.0 release for linux 16 because i have only libcudart9.0 and an old SM 3.7 compute capability i tried to edit the makefile.in to add 3.7 arch and remove the 7.5 arch that do not work with cuda 9.0 but the lyra2/lyra2z.cu trigger some error as 3.7 was not intended when was compiled and i couldn't figure it out how to change or remove the checks for arch in that file so can u guys create a cuda 9.0 for 3.7 compute capabilities card release removing from the code the need for newer like 7.5 arch?

hmm... I am pretty sure that there is already binaries for cuda 9 in the release area... oh cuda 9.2 and you want cuda 9.0...

there is a very easy fix to your problems: Upgrade your nvidia drivers...
there hasn't been a good reason to use cuda 9.0 since at least 4 years... so upgrade your drivers, whatever card you are using will still be supported by more recent cuda version

what card are you using by the way ? For info mtp requires at least 4.4Gb of vram

[mrschaeffer2018]

I'm using the institute that i work k80 the people there are ok with that, they are idle most of the time but i can't upgrade the CUDA yet they have old stuff running and would require a protocol if i paste the log of error in the lyra2/lyra2z.cu file that prevents me to compile probably because of older 3.7 SM do you believe you can help me with some tweaks? Maybe removing the parts that says about newer cards as i will not gonna use it.

I'll have a look later in the day, that lyra2/2z version wasn't written by me... and is a huge pain in the way it was written (unnecessary complication to work for various platform).

Does the k80 has enough memory ?
To be honest, the performance on kepler won't be great as it is a rather old architecture

[mrschaeffer2018]

Yes the k80 have 12gb i don't know about performance but as long as i have a lot of them in idle availble by quantity it can compensate it.

[djm34]

sorry, I'll try to have a look soon. what is the compute version of the kepler ?

[mrschaeffer2018]

The compute version it is 37, thanks for responding and for the effort in help, thank you.

Hi, just updating the issue, i was able to start the miner downloading another libcudart-9.2 and pointing to that lib when executing the miner, but when started i get this error below, do you know what coud it be?

Would be that due to using CUDA 9.0 not 9.2 ?
