Dear Mike
So you confir my doubt. I'v to see why this NCBI program is using more
than one thread!!!

Jerome,
It just means that your job used more than one CPU ( probably multithreaded
task, or something is running In parallel) SGE doesn't limit your job to use
more CPUs than slots requested ( in general - the slot is abstract and just a
place on the server for the job, not physical CPU. ).
Best regards,
Mikhail Serkov

I'm surprise that the wallclock time (1761) is less than the cpu time (2171) ,
in a single core jobs. In this case, i've got an eficiency more than 120 % !!!
I'm sure i'm wrong, but can't know where..
Thanks.

Si le problème a une solution, il ne sert à rien de s'inquiéter.
Mais s'il n'en a pas, alors s'inquiéter ne change rien.
