通过以下指令序列,您可以启用 GPUDirect RDMA 在 GPU 内存中分配 mempool ,并将其注册到设备网络中。 struct rte_pktmbuf_extmem gpu_mem; gpu_mem.buf_ptr = rte_gpu_mem_alloc(gpu_id, gpu_mem.buf_len, alignment)); /* Make the GPU memory visible to DPDK */ rte_extmem_register(gp...

(3). 安装完nv_peer_mem, 如果想查看其状态可以 /etc/init.d/nv_peer_mem/ status 如果发现没有此文件,则可能安装的时候没有默认拷贝过来,需要拷贝即可: cp/tmp/nvidia-peer-memory-1.3/nv_peer_mem.conf /etc/infiniband/cp/tmp/nvidia-peer-memory-1.3/debian/tmp/etc/init.d/nv_peer_mem /etc/init...
This way the rkey for a memory region can be changed frequently. GPUDirect Over DMA-BUF [All HCAs] Added support for GPUDirect support over dma-buf. As such, using the new mechanism nv_peer_mem is no longer required. The following is required for dma-buf support: Linux kernel version...
If the nvidia_peer_memory module is not loading: DGX OS 5.1.1 provides nv_peer_mem 1.2 and MLNX_OFED 5.4-3.1.0.0 to resolve an issue discovered in MLNX_OFED 5.4-1.0.3.0. nv_peer_mem 1.2 isn’t compatible with MLNX_OFED <= 5.4-1.0.3.0, and attempting to use nv_peer_mem 1.2 with...
6. 安装nv-peer-memory 针对GPU A系列裸金属服务器,需要重新安装nv-peer-memory, 因为在步骤1中已经被卸载了。 gitclone https://github.com/Mellanox/nv_peer_memory.gitcd./nv_peer_memory ./build_module.shcd/tmptarxzf /tmp/nvidia-peer-memory_1.3.orig.tar.gzcdnvidia-peer-memory-1.3 ...
而不同类型的通信(peer2peer,collective)有不同的队列(queue),每个通信都会变成queue的task,每个task 都会被NCCL 编排成一个plan,plan 包括一次通信需要的资源(channel/grid数量,thread 数量/warps 对齐的)。 stream 机制 Stream 介绍过,作为host侧提交kernel 任务的组织单位。 Communication 自身的stream if (parent...
If the nv_peer_mem, gdrdrv or nv_rsync_mem module are not loaded, verify the NVIDIA Peer Memory Override is set: grep PeerMappingOverrid /proc/driver/nvidia/params RegistryDwords: "PeerMappingOverride=1"\ In a diskless and diskful environment, the/etc/...
Added the nvidia-peermem.ko kernel module. This module provides Mellanox InfiniBand HCAs (Host Channel Adapters) direct peer-to-peer access access to NVIDIA GPU memory without need without needing to copy data to host memory. See the chapter "GPUDirect RDMA Peer Memory Client" in the README ...
