Description:Starting from GPU Driver version r465, nv_peer_mem was shipping in the GPU driver package under the name nvidia-peermem. Updating OFED required nvidia-peermem rebuild, otherwise it was stubbed out by the kernel. Keywords:Installation, GPU Driver ...

NVIDIA GPUDirect RDMA 使用 PCI Express 的标准功能,为 GPU 和第三方对等设备之间的数据交换提供了直接路径 要在Linux 系统上启用 GPUDirect RDMA ,需要nvidia-peermem模块(在 CUDA 11.4 及更高版本中提供)。图 3 显示了最大化 GPUDirect RDMA 内部吞吐量的理想系统拓扑:在 GPU 和 NIC 之间使用专用...
Installing nvidia_peermem For CUDA 11.5.1 and later, if you plan to use Weka FS or IBM SpectrumScale then you need to run: $ modprobe nvidia_peermem This will load the module that supports peer-direct capabilities. It is necessary to run this command after reboot of the system. In ...
此外,NVIDIA 510.47.03 引入了一个名为 nvidia-powerd 的新守护程序,它在受支持的系统上提供了对Dynamic Boost特性的支持,以提高性能,以及一个名为 peerdirect_support 的新模块参数 nvidia-peermem.ko 内核模块,以正确支持GPUDirect RDMA在MOFED 5.0和更老版本。
(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...

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 ...
To enable GPUDirect RDMA on a Linux system, thenvidia-peermemmodule is required (available in CUDA 11.4 and later). Figure 3 shows the ideal system topology to maximize the GPUDirect RDMA internal throughput: a dedicated PCIe switch between GPU and NIC, rather than going through the system ...
