Dear All,
There is an argument going on on the CMS computing management list about
whether or not CMS' internal management of single and multicore jobs
inside a single multicore pilot is more or less efficient than the
draining of the node that a batch system must do in order to run a
mixture of single and multicore jobs. Thanks to Andrew L. I have figures
(or rather graphs) for the inefficiency inside the CMS multicore pilots
but does anybody have figures for the inefficiency caused by batch
system draining for aa mixture of jobs? Perhaps through looking at Atlas
jobs where they run single core jobs in single core pilots and multicore
jobs in multicore pilots.
Any information would be very very welcome.
Best,
david
