By enabling the P2P feature, will feature GPUDirect RDMA also be activated for the RTX 4090 graphics card? |
Beta Was this translation helpful? Give feedback.

Enabling P2P alone won't get you GPUDirect RDMA on the RTX 4090. That feature is mainly for Tesla and Quadro GPUs, as they have the required hardware support. The RTX 4090 indeed powrful but it is designed more for gaming and creative workloads, not for the HPC scenarios where GPUDirect RDMA is typically used. So, even with P2P turned on, don't expect RDMA to work on an RTX 4090. |
