Hi,
I am currently seeing similar performance for cuFIleRead in terms of POSIX compatible mode and GDS. I can see that the NVMe driver is supported from gdscheck. However, upon executing the sample programs the only errors that I can see in cufile.log is.
ERROR 0:106 cuDeviceGet failed with error 4
Does this affect the performance in anyway? why is my CUDA kernel shutting down, as shown by error 4: CUDA_ERROR_DEINITIALIZED?
GDS release version: 1.5.0.59
nvidia_fs version: 2.14 libcufile version: 2.12
