我正在尝试在多节点集群上安装 openMPI 和 mpich2，但在这两种情况下我都无法在多台机器上运行。 使用 mpich2 我能够从头节点在特定主机上运行，但是如果我尝试从计算节点运行某些东西到不同的节点，我会得到： HYDU_sock_connect (utils/sock/sock.c:172): unable to connect from "destination_node" to "parent_node" (No route to host) [proxy:0:0@destination_node] main (pm/pmiserv/pmip.c:189): unable to connect to server parent_node at port 56411 (check for firewalls!)如果我尝试使用 sge 来设置作业，我会遇到类似的错误。 另一方面，如果我尝试使用 openMPI 来运行作业，我将无法在任何远程机器上运行，即使是从头节点。 我得到： ORTE was unable to reliably start one or more daemons. This usually is caused by: * not finding the required libraries and/or binaries on one or more nodes. Please check your PATH and LD_LIBRARY_PATH settings, or configure OMPI with --enable-orterun-prefix-by-default * lack of authority to execute on one or more specified nodes. Please verify your allocation and authorities. * the inability to write startup files into /tmp (--tmpdir/orte_tmpdir_base). Please check with your sys admin to determine the correct location to use. * compilation of the orted with dynamic libraries when static are required (e.g., on Cray). Please check your configure cmd line and consider using one of the contrib/platform definitions for your system type. * an inability to create a connection back to mpirun due to a lack of common network interfaces and/or no route found between them. Please check network connectivity (including firewalls and network routing requirements).这些机器相互连接，我可以从任何机器到任何其他机器进行 ping、无密码 ssh 等操作，MPI_LIB 和 PATH 在所有机器中都设置得很好。 |
