The parallel version of VASP can be compiled successfully on my system.
However, when running VASP will abort immediately after it is started due to “LAPACK: Routine ZPOTRF failed!”
I have fixed this problem by lowering the optimization level of mpi.F.
Since the NEB method essentially requires ...

Thanks a lot for your kind help.
Since on my system it provides command mpijob instead of mpirun. And the reference manual tells me that the parallel and serial jobs should be submitted in the same way. I tried to submit my task like this:
bsub -q rms –n 16 prun ~/bin/vasp
Then the top lines of ...

Thank you very much for your reply.

It seems that only 1 processor performing the task. But when I type bjbos command, 16 CPUs are listed:

Dear all:
When performing NEB calculation I specified IMAGES=2 and created four subfolders named
00, 01, 02, 03, respectively.
But I found that only 01/ contained output files, so I doubted that the IMAGES may be changed in the executing.
I added some tracking statements to the source file and ...

Dear all:
I have performed some calculations with NEB method these days. Some errors were encountered!
I checked the OUTCAR in subfolder 01/. (IMAGES=1)
These are the last lines of OUTCAR:
