首先openmpi要设置好跨机器的配置。我的环境是ubuntu18.02. 第一个坑: 使用sudo apt install 安装的openmpi版本是2.x的,跨机运行nccl的时候会报错。 Warning: There was an error initializing an OpenFabrics device. 最后发现是因为版本太低了,所以换成4.x的,在官网build from source: https://www.open-mpi....
This issue looks related to #3268 and #3210; however, the suggestions in those issues don't seem to resolve the crash I'm getting. I'm using OpenMPI 4.0.0 with UCX 1.4, built from source, on RHEL 7 using CUDA 10. Here is a simple program...

If Open MPI cannot find one, it will fall back to build and use the internal copy of hwloc included in the Open MPI source tree. Alternatively, the --with-hwloc option can be used to specify where to find the hwloc support headers and library. The following VALUEs are permitted: ...
