help to solve P4-error for vasp question

#1 Post by bendix » Sun Jun 24, 2007 9:53 am

When running some cases like NEB-case, I often meet the below error!
Try to solve this error about one month, but i don't success until to now!
The errors let to me crazy... :(
Can anyone help me, please?

my lib-machines
compiler:IFC 9.1.040
lib.:MKL 9.0
CPU: Intel core 2 duo E6600
distr.:Fedora core 6
MPI: mpi-1.2.7p1 + mpiexec-0.82
PBS: torque

sorry, this error is not due to vasp but probably due to some
communication problem. Please in any case make sure that VASP has been compiled with the same integer byte-length as your MPI .

I find about this question recently.
When used ISPIN=2 in NEB-case, this error exhibits right now.
Just close spin(ISPIN=1 or comment ISPIN), VASP can run NEB-case.
I try this parameter (ISPIN) of NEB in the two different clusters, all machines have the same error!

why? Please tell me! :(
thanks~~

I use the parameters in INCAR, below...
SYSTEM=adsorption process
ISTART=0
ICHARG=2
ISIF=2
IBRION=1
NPAR=8
ISMEAR=0
SIGMA=0.1
LREAL=Auto
ALGO=Fast
LPLANE=.TRUE.
NSIM=4
NSW=30
PREC=Accurate
IMAGES=4
SPRING=-5
ISPIN=2

sorry, I cannot reproduce this error. Using LAM and mpirun, there is no difference whether a NEB calculation is done for a magnetic or a non-polarized system.
