Open questions:
Sorry for the change in format but I am finding using the bullets in Confluence to be troublesom so I am trying something else.
How can one see nodes that are entirely unclaimed?
I want a proper subset of machines to be for the HERA project. These machines will only run HERA jobs and HERA jobs will only run on these machines. This seems to work..
| machine config | submit file |
|---|---|
HERA = True STARTD_ATTRS = $(STARTD_ATTRS) HERA START = ($(START)) && (TARGET.partition =?= "HERA") | requirements = (HERA == True) +partition = "HERA" |
But is there a better way? I was hoping I could do something like this but it seems to confuse condor and the jobs run on any machine.

- 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?
