Re: [condor-users] precise time logging ?

[Douglas Thain <thain@xxxxxxxxxxx>]

Hello Michal,

Please keep in mind that Condor is a high *throughput* system designed to
execute large workloads over long time periods.  It is *not* designed to be
a low latency system that executes a single job quickly.  Condor performs a
large number of expensive operations in order to maximize scalability and
relability at the expense of latency.

If you take measurements of job submission, placement, and execution, you
will see variances on the order of *minutes*, not microseconds.  This is
fine for most of our users, who generally run jobs measured in hours or
days. Increasing your measurement precision to 1/100 second isn't going to
reveal any useful information about Condor.

That said, please keep us posted on what you are trying to
do, and best of luck.

Cheers,
Doug
