问题描述
Azure HPC仅支持Intel MPI 5吗?还是可以使用Open MPI?我尝试从源代码构建Open MPI，但它只能识别TCP网络.然后，我尝试从yum安装Open MPI，并且该驱动程序识别出infiniband驱动程序.但是，几乎 所有测试程序都将挂起.唯一有效的是主机名"命令.如果我尝试编译一个简单的hello world c程序，它将在运行时挂起.
Is only Intel MPI 5 supported on Azure HPC? Or can one use Open MPI? I tried building Open MPI from source but it would only recognize the TCP network. I then tried installing Open MPI from yum and that one recognized the infiniband drivers. However, almost all test programs would hang with it. The only thing that worked was the "hostname" command. If I tried to compile a simple hello world c program, it would just hang when run.
推荐答案
Azure中当前启用RDMA/IB的VM大小需要Windows上的MSMPI/英特尔MPI 或Linux上的Intel MPI .
Current RDMA/IB enabled VM sizes in Azure require either MSMPI/Intel MPI on Windows or Intel MPI on Linux.
