#### Known issues
On systems running Linux kernel 6.8.0, such as Ubuntu 24.04, GPUDirect RDMA is disabled and impacts multi-node RCCL performance.
On systems running Linux kernel 6.8.0, such as Ubuntu 24.04, Direct Memory Access (DMA) transfers between the GPU and NIC are disabled and impacts multi-node RCCL performance.
This issue was reproduced with RCCL 2.20.5 (ROCm 6.2.0 and 6.2.1) on systems with Broadcom Thor-2 NICs and affects other systems with RoCE networks using Linux 6.8.0 or newer.
Older RCCL versions are also impacted.
