segmentation fault after 5 iterations

[Pär Olsson]

Hi there,

I get segmentation fault after 5 iterations when trying to run large supercells with VASP. I have a box with 240 atoms and use gamma point only. I paste the INCAR and makefile below.
Can anyone help me out?
The cluster consists of dual opterons with 6Gb per box (3 Gb per cpu) and are linked together with a fast myrinet. mpich handles the MPI communication. I am running vasp4.6.

thanks!

# BLAS must be installed on the machine

# retrieve the lapackage from ftp.netlib.org
# and compile the blas routines (BLAS/SRC directory)
# please use g77 or f77 for the compilation. When I tried to
# use pgf77 or pgf90 for BLAS, VASP hang up when calling
# ZHEEV (however this was with lapack 1.1 now I use lapack 2.0)
# 2) most desirable: get an optimized BLAS
# for a list of optimized BLAS try
# http://www.kachinatech.com/~hjjou/scilib/opt_blas.html
#
# the two most reliable packages around are presently:
# 3a) Intels own optimised BLAS (PIII, P4, Itanium)
# http://developer.intel.com/software/products/mkl/
# this is really excellent when you use Intel CPU's
#
# 3b) or obtain the atlas based BLAS routines
# http://math-atlas.sourceforge.net/
# you certainly need atlas on the Athlon, since the mkl
# routines are not optimal on the Athlon.

# MPI section, uncomment the following lines
#
# one comment for users of mpich or lam:
# You must *not* compile mpi with g77/f77, because f77/g77
# appends *two* underscores to symbols that contain already an
# underscore (i.e. MPI_SEND becomes mpi_send__). The pgf90
# compiler however appends only one underscore.
# Precompiled mpi version will also not work !!!
#
# We found that mpich.1.2.1 and lam-6.5.X are stable
# mpich.1.2.1 was configured with
# ./configure -prefix=/usr/local/mpich_nodvdbg -fc="pgf77 -Mx,119,0x200000" \
# -f90="pgf90 -Mx,119,0x200000" \
# --without-romio --without-mpe -opt=-O \
#
# lam was configured with the line
# ./configure -prefix /usr/local/lam-6.5.X --with-cflags=-O -with-fc=pgf90 \
# --with-f77flags=-O --without-romio
#
# lam was generally faster and we found an average communication
# band with of roughly 160 MBit/s (full duplex)
#
# please note that you might be able to use a lam or mpich version
# compiled with f77/g77, but then you need to add the following
# options: -Msecond_underscore (compilation) and -g77libs (linking)
#
# !!! Please do not send me any queries on how to install MPI, I will

usually a calculation segfaults if the memory requirements get too large or if there are some allocation errors (eg due to improper compilation)
both should not be the case with your calculation and memory limits.
please send a more detailled error report to find out at which point the calculation actually
crashes (mixing, diagonalisation,???): this report should include
OUTCAR,OSZICAR and the job.stdout file
please let me make 2 short remarks
--) for 240 Fe atoms/cell,
MAGMOM = 240*4
is sufficient
--) if you want to obtain reliable results from quantities derived from the stress tensor (ISIF = 2) , you should take the highest precision
PREC= High
in INCAR

[admin]

there is one thing I completely overlooked (sorry): please choose either -DwNGXhalf or -DwNGZhalf (not both of them at once) as precompiler flags
