Node "ComputeNode1" became unreachable. Ensure that all nodes are available and submit the job again. RRS feed

  • Question

  • Hi all,

    I have HPC 2012 R2 and all my system servers are "Windows 2012 R2". I have 8 compute nodes and one of them started to give this error at the same step of a task.

    At first phases of the job, Compute node 1 starts to working with 32 cores, at the last phase of job it requires more cpu and allocate from Compute Node 2, after couple of mins later task finished with below error. Until today it was working well also this node succesfully worked many times in today.

    "Node ComputeNode1 became unreachable. Ensure that all nodes are available and submit the job again."

    I checked the "C:\Program Files\Microsoft HPC Pack 2012\Data\LogFiles\Management\" but there is no log belongs to my failure time period (most fresh one belongs 12 hours ago9

    Thank for your answers.
