- 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?
