Open questions:

  • How can one see nodes that are entirely unclaimed?


  • Bug where James's jobs are all put on the same core.  Here is top -u krowe showing the Last Used Cpu (SMP) after I submitted five sleep jobs to the same host.
    • Is this just a side effect of condor using cpuacct instead of cpuset in cgroup?
    • Is this a failure of the Linux kernel to schedule things on separate cores?
    • Is this because cpu.shares is set to 100 instead of 1024?
    • Check if CPU affinity is set in /proc/self/status
    • Is sleep cpu-intensive enough to properly test this?  Perhaps submit a while 1 loop instead?
