cannot connet to head node from local host RRS feed

  • Question

  • Hi, I am using the ccs 2003. I want to use computing node 1 and 2 (16 processor in total), I can send the job using the user interface on CN01 and there is no problem. But when I tried the command line: c:\documents and settings\hpcuser> job submit /numprocessors:16 /askednodes:cn01,cn02 mpiexec -hosts 2 cn01 cn02 mpitest2.exe
    the system tells me that cannot connect to head node from 'localhost'.

    Does someone experience the same problem? Furthermore, the reason I use the command line is that I hope to place rank 0 on CN01, rank 1 on CN02. Then rank 0 and rank 1 can pass message between each other, then they can initialize OpenMP on their own node for future use. Is it possible to do this on ccs 2003?

    Thanks and regards

  • Hi Skiff,

    The cmd line should work if running from head node.  "> job submit /numprocessors:16 /askednodes:cn01,cn02 mpiexec -hosts 2 cn01 cn02 mpitest2.exe"?

    Can you tell me on which node you are running your command line?

    If you run it from CN01, please add option "/scheduler:<headnode>" to the above command, then it should work.
