通过网络运行 UPC 代码时出现问题：连接被拒绝
当我在 2 个节点的网络上运行 UPC 代码时，启用 -v 选项以提供执行的详细信息，我注意到主节点 (glitch.rutgers.edu) 尝试连接到自身，而不是连接到它的相邻节点。
/usr/bin/rsh glitch.rutgers.edu -l sharatds -n '/usr/bin/env'
'GASNET_MAX_SEGSIZE='74344KB'' 'GASNET_VERBOSEENV='1'' '/cac/u01/sharatds/UPC_Tests/./upcMatrxMultplction_mpi' glitch.rutgers.edu 41449 \-p4amslave \-p4yourname glitch.rutgers.edu \-p4rmrank 1
glitch.rutgers.edu: Connection refused
p0_5078: p4_error: Child process exited while making connection to remote process on glitch.rutgers.edu: 0
p0_5078: (45.046875) net_send: could not write to fd=4, errno = 32
gasnetrun: unlinking gasnetrun_mpi-temp-4813/rsh gasnetrun_mpi-temp-4813/ssh gasnetrun_mpi-temp-4813/mpirun-rsh gasnetrun_mpi-temp-4813/mpirun-tmp
为什么会出现这种情况？对配置的任何更改都应该设置正确吗？
感谢您的帮助
when I run a UPC code over a network of 2 nodes, with -v option enabled to give me detailed information of execution, I notice that the master node (glitch.rutgers.edu) tries to connect to itself as opposed to connect to it's neighbouring nodes.
/usr/bin/rsh glitch.rutgers.edu -l sharatds -n '/usr/bin/env'
'GASNET_MAX_SEGSIZE='74344KB'' 'GASNET_VERBOSEENV='1'' '/cac/u01/sharatds/UPC_Tests/./upcMatrxMultplction_mpi' glitch.rutgers.edu 41449 \-p4amslave \-p4yourname glitch.rutgers.edu \-p4rmrank 1

Why is this happening ? Any changes to the configuration should set this right ?

此错误可能来自 rsh...您可以通过尝试从主节点运行 rsh 命令回自身来确认这一点，例如“rsh glitch pwd”（我猜测这会提示您输入密码）。
this error is likely from rsh...you can confirm this by trying to run an rsh command from the master node back to itself like "rsh glitch pwd" (my guess is this will prompt you for a password).
