<blockquote type=cite class=cite cite>I have a litlle problem with my
cluster of 6 pcs running gromacs, When the job starts the md run well but
then the job is very slow, using only 4% of each procesors, so my
question is. Is there any command to use at the best performance the
procesors? I am using lammpi, maybe there is a comand to indicate
that.</blockquote><br>
It may just be a scaling issue. The smaller the system size, the
worse the scaling as you go to more CPUs. It is also very important
how the boxes are communicating with each other, the faster the hardware
you are using, the better the scaling will be.<br><br>
Have you tested how the system you have and run scales over the 1, 2, 4
etc CPUs?<br><br>
