VASP Stops after >> parallel 3dFFT charge

[aldo]

Hi,
I'm running VASP 4.6 in a SGI Xeon250 cluster. Executable created with Intel 10 compilers and Intel mkl libraries, as well as /opt/intel/mkl/10.1.2.024/lib/em64t/libfftw3xf_intel.a for FFT.
Any job I run, no matter the number of processors, ends after:

Code: Select all

parallel 3dFFT wavefunction:
    minimum data exchange during FFTs selected (reduces bandwidth)
 parallel 3dFFT charge:
    minimum data exchange during FFTs selected (reduces bandwidth)

I use Torque/MPI, and this is the output of the job.err:

Code: Select all

Apparently it gets stuck when doing FFTw stuff, any ideas?

By the way, the serial version os VASP works well...
