I have a problem with mvapich2-jobs: if 2 jobs share the same host (e.q. two 4
core jobs on a 12 core host), then the SGE allocates partly the *same* cores to
the two jobs so every one is only getting 50% cpu time. How can this be avoided?
did you request any "-binding" to `qsub`? Otherwise it should be an effect of
the scheduler in the kernel.

No, no "-binding" to qsub. The selection should make the SGE. But it
does not check that some cores are already used and chooses the same one
a second time.
