compute_30 error while compiling on RTX 2080 and ubuntu 20.04 #376

Open mirameshs opened 1 year ago

mirameshs commented 1 year ago

there is an error while I was compiling on RTX 2080 and Ubuntu 20.04. the command I used : sudo make BUILD_CUDA=1

can you help me how to solve and compile the code? I have searched for this error and found something. for example, someone suggested remote compute_30 in one of the files. Of course, this solution was not for this project but it was for a project similar to vanitysearch. I think this problem also exists on RTX 3090 and any high-level GPUs.

thanks in advance

Hello,

I hardly remember having similar problem, if it can help you can try to modify your Makefile.

In my case :

--- a/Makefile +++ b/Makefile @@ -13,7 +13,7 @@ CXX=g++ CXXFLAGS=-O2 -std=c++11

CUDA variables

-COMPUTE_CAP=30 +COMPUTE_CAP=86 NVCC=nvcc NVCCFLAGS=-std=c++11 -gencode=arch=compute_${COMPUTECAP},code=\"sm${COMPUTE_CAP}\" -Xptxas="-v" -Xcompiler "${CXXFLAGS}" CUDA_HOME=/usr/local/cuda

Note that you need to find the compute capacity of your GPU, I have a 3060Ti which is CC 86. It seems the CC is 75 for a 2080 Ti

Another thing to look is maybe the nvidia software you installed on your computer, this error may me think you installed a recent one that does not handle anymore CC 30 GPU, I got an issue with other tools (on windows) of this kind (having to use cuda 10.2 instead of 12.x), but I cannot help on this one. btw 30 is not linked to 30xx series, it's very old graphics cards like 7xx serie ...

thank you. You are great and please let me know how much is your benchmark with 3060Ti?

I have around 890 MKeys/s with a 3060Ti.

Salaam alaikum to everyone! Hello everyone! Bitcoin is a scam! On March 19, 2024, 865 bitcoins were sold on the exchange at a price of $8,000! On other exchanges the price was $70,000! Let's create a community and sequentially select the private key of the largest bts address! And when we find it, Bitcoin will collapse! Thanks in advance everyone!
