Hi,

I'm trying to get vasp to work on some opteron systems. The used compiler is Pathscale, with netlib lapack and blas. The serial version works ok, but the mpi version stops with the following error:
ERROR in FFT3RC: this version does not support the required half grid mode

could someone please explain me what this means (or better yet, how to fix it)?

Thank you for your time.

the precompiler options to use halfgrid mode are different for
serial and parallel executables and have to be changed accordingly:
serial CPP = ..... -DNGXhalf
parallel CPP = .... -DNGZhalf
