Hello,
I have installed CUDA 11.7 and GDS on Ubuntu 20.04 machine along with MLNX_OFED.
As per instructions, I have mounted filesystem as and tried to run sample code
#mount /dev/nvme0n1p8 /mnt -o data=ordered
#sudo ./cufile_sample_001 /mnt/fs2 0
opening file /mnt/fs2
file register error:GPUDirect Storage not supported on current file
properties.use_compat_mode : false
I have enabled logs and found below error
