hello expert

could you please help take a look this code? it failed to build now.

Hi @gaowayne ,

This project has not gotten any attention the last few years, and the source is getting a bit old. I would assume the error is related to the GPU architectures I build for. These numbers are passed to nvcc as sm_XX and compute_XX and I think NVIDIA has dropped support for the older ones.

ssd-gpu-dma/CMakeLists.txt

Line 16 in da5aade

set (nvidia_archs "30;50;52;60;61;70" CACHE STRING "NVIDIA compute architectures")

You can try removing the older ones, and you would perhaps need to add newer ones as well. I see that the BAM project adds 70, 80 and 90: https://github.com/ZaidQureshi/bam/blob/f3da31e8ed141c352b96d5ad9fe9b350fa1b081f/CMakeLists.txt#L18
