Bug in the job report ? RRS feed

  • Question

  • Hi,
    during my tests on a cluster with 8 compute nodes, I found a mismach in the nodes allocation.

    Precisely, I ran 3 jobs simultaneously with 3 tasks each one:
    (requested resources: Auto-Auto Nodes)

    task 1.1 takes Node1 ,  task 1.2 takes Node2 ,  task 1.3 takes Node3
    task 2.1 takes Node4 ,  task 2.2 takes Node5 ,  task 2.3 takes Node6

    for the job3, the View Job dialog says that it takes the nodes 4,7,8
    but the Task Properties of the job says that it takes the nodes 7,8,8.

    (I don't know if the task has run in the Node4 or in the Node7)

    If you need more informations or screenshots, I can provide them privately.

    Bring me up to date :)

    Thanks,
    Marco

  • Marco,
    I think this is what is happening:
    1. Job is allocated 3 nodes (4, 7, and 8)
    2. Task 1 is started on Node 7
    3. Task 2 is started on Node 8
    4. Task 2 finishes very quickly, since all they do is a dir
    5. Task 3 is started on Node 8 since it is already availale

    I think if you used longer running tasks, you'd see more of the expected behavior.

  • Hello Marco,
    It would be helpful to see the data you are talking about.  You can e-mail me screenshots if you'd like (jbarnard at microsoft dot com).  Easier might be to just run a job view and task view (possibly the with /details flag) from the command line and post the output of that up here.

    Thanks,
    Josh
