Electronic convergence fails for large systems!!

Posted: Thu Nov 01, 2007 10:46 pm
by ytiwary
I have installed the parallel version of vasp4.6 using Intel fortran compiler for a Linux Opteron system. It runs perfectly fine for a system with few atoms (approx less than 60) but for more atoms the electronic runs fail to converge. The same system converges easily on other clusters with the same INCAR file. I am including my INCAR and Makefile here. I have tried both internal and fftw-3.0.1 and 3.1.2 version of the fft libraries but nothing works. If anyone has experienced this problem or you have idea what is going on, please help me.

Thanks,
Yogesh

# Makefile for Intel Fortran compiler for Operton systems
#
# The makefile was tested only under Linux on Intel platforms
# (Suse 5.3- Suse 9.2)
# the followin compiler versions have been tested
# 5.0, 6.0, 7.0 and 7.1 (some 8.0 versions seem to fail compiling the code,
# 8.1 is slower than 8.0)
# presently we recommend version 7.1 or 7.0, since these
# releases have been used to compile the present code versions
#
# it might be required to change some of library pathes, since
# LINUX installation vary a lot
# Hence check ***ALL**** options in this makefile very carefully
#-----------------------------------------------------------------------
#
# BLAS must be installed on the machine
# there are several options:
# Kazushige Goto's BLAS is required
# http://www.cs.utexas.edu/users/kgoto/signup_first.html

#
# FFT:
# the fftw.3.0.1 must be available and installed, since
# the ifc compiler creates crap code if the build in fft routines are used

# 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/ifc
# compilers however append only one underscore.
# Precompiled mpi version will also not work !!!
#
# We found that mpich.1.2.1 and lam-6.5.X to lam-7.0.4 are stable
# mpich.1.2.1 was configured with
# ./configure -prefix=/usr/local/mpich_nodvdbg -fc="pgf77 -Mx,119,0x200000" \
# -f90="pgf90 " \
# --without-romio --without-mpe -opt=-O \
#
# lam was configured with the line
# ./configure -prefix /opt/libs/lam-7.0.4 --with-cflags=-O -with-fc=ifc \
# --with-f77flags=-O --without-romio
#
# 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
# certainly not answer them !!!!

strange, are there any hints in the job.stdout file?
