Right, from what I remember, it never sets the active state. The jobs
in question probably took less than 1 sec to execute, so seeing 8
seconds between submitted and completed looks fine to me. The fact
that the timestampts on the file/dir is later than the time Falkon says
the job completed is an indication that either the clocks are not in
sync (bbogin and fd-login.mcs are in sync, but what about bblogin and
SiCortex compute nodes?), or NFS did not process the write operation
immediately, and under the heavy load of 60 workers ll writing at the
same time, it took 5 seconds to complete the write operation. Mike,
where are the Falkon logs, to see what happened from Falkon's point of
view.<br>

I assume that your submit host and the various machines involved have
properly synchronised clocks, but I have not checked this beyond seeing
that the machine I am logged into has the same time as my laptop. I have
labelled the times taken from different system clocks with lettered clock
domains just in case they are different.
For this job, its running in thread 0-1-88.
The karajan level job submission goes through these states (in clock
domain A)
23:14:08,196-0600 Submitting
23:14:08,204-0600 Submitted
23:14:14,121-0600 Active
23:14:14,121-0600 Completed
Note that the last two - Active and Completed - are the same (within a
millisecond)

That probably means the provider doesn't really set the active state,
and it gets filled in when "completed" arrives.
