Can connectx-4 455a support GPUDirect?

Hello,

I couldn’t find and doc about this. So, can 455a support the GPUDirect?

1b:00.0 Ethernet controller: Mellanox Technologies MT27700 Family [ConnectX-4]

Thanks

What does 455a stands for?
In general GPUDirect RDMA is supported on ConnectX-4 NICs. There may be some minimal CUDA required and GPU (Nvidia). If it is from the last x years (in the single digit) you should be ok, but I do suggest one of the latest ones.
You should be aware that there are limitations documented here: GPUDirect RDMA
