Hi *,
Took a look at the monitor page
http://gridportal.hep.ph.ic.ac.uk/rtm/sites_report.html
today (for NIKHEF of course) and saw something I must not understand.
For NIKHEF (at 14.51 dutch time) the page said
519 jobs submitted
512 jobs successful
2 jobs aborted
5 jobs cancelled
looks pretty good, so why does it say that the percent of CPU time doing
useful work is only 48%? In fact it looks like there must be some logic
error in the calculation, there are many sites with 100%, then NO sites
with useful time percentages between 50 and 99 percent, then the rest
are spread between zero and 49%, with some evidence of skewing towards
values of 48 to 49%.
For example take ce2.egee.cesga.es ... with 369 submitted jobs, 367 of
which were successful, still 49% "useful time".
Explanation?
