[Swift-devel] Re: swift-falkon problem

[Ioan Raicu]

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.
