Dear Vasp users.

I'm tryng to use Vasp for mpi version of Vasp4.6.28 on Linux EM64t platform
with FFTW. The fortran compiler is IFC8.0.
I could compile the Vasp for mpi, but when I run vasp, the calculation stopped
with the message,

p2_19530: p4_error: interrupt SIGSEGV: 11
rm_l_2_19531: (10.910156) net_send: could not write to fd=5, errno = 32
p2_19530: (10.910156) net_send: could not write to fd=5, errno = 32
p1_20798: p4_error: interrupt SIGx: 13

What is the problem for running the vasp?

Parts of my Makefils is as follow,

and so on.

where does this segmentation fault occur?

Dear admin.

Thank you for reply.

I can run the Vasp by myself.
I found previous

http://cms.mpi.univie.ac.at/vasp-forum/ ... .php?3.741

I changed the file fftmpiw.F as previous job's potst,
and I could run the parallel Vasp on Em64t with FFTW3.0.
