Using this flag a version is compiled which supports the nudged elastic band method. The mpif.h file must be created in the same way as explained above. Most files will be compiled in the same way as in the serial version (for instance no parallel FFT support is required). In this case each image, must run on one and only one node, the tag IMAGES must be set to the number of nodes:

 IMAGES = number of nodes
This version is as fast as the serial version (and thus usually faster than the full MPI version), and can run very efficiently on clusters of workstation.

VASP.4.4 and VASP.4.5 currently do not support this flag properly

N.B. Requests for support are to be addressed to:
