Also the machine (where now I've the problem) before worked as the other
machine... I don't know before "what".
However...I start from a file .gro where is my system ready for
constraint forces; I use grompp:
"grompp_d -f MD_Eq.mdp -c DNA5x3_min.gro -p DNAx3.top -o DNA6x3_MD.tpr
-n indexAcqua.ndx -po mdout.mdp"
and later mdrun:
"mdrun_d -nice 0 -v -s DNA6x3_MD.tpr -pi pull.ppa -po pullout.ppa -pdo
pull.pdo -o mdEq_traj.trr -c DNA6x3_MD.gro -e mdEq_ener.edr -pn
indexAcqua.ndx -x mdEq_traj.xtc -g EqD.log"
I don't use mpirun.
There is no differences between the way to prepare calculations.
one machine is a notebook (centrino duo)
the other machine is a Desktop (AMD64 X2)
the kernel is the same (2.6) debian.
with the code written above notebook uses only one processor, Desktop
uses both the cpu.
I repeat...I also worked in this manner, and also the notebook has ever
worked until some week ago.
Now for use both the cpu I must use mpirun.
Desktop kernel is non smp
Laptop kernel has both smp and non-smp.
