I have some very important jobs running in my cluster (SGE 6.1u4) that
are taking too much time. I wanted to check why they were taking so long
and I have found out they where running in the node with a nice value of
19 (the lowest). I have tried to renice them but nothing happened. The
most I have seen is when I reniced them while using "top", then I saw
the priority modified ( for instance, to -10) for a second, and the next
second the priority went back to 19. The only thing I have been able to
renice is the sge_shepherd process.
Is SGE preventing my renice in some way? Is it a known issue?
Thanks in advance,
