VASP installation on Opteron246 cluster

#1 Post by odelaire » Fri Sep 03, 2004 1:12 am

Hello,

We have recently purchase a license for VASP. I have downloaded the package
and so far the sequential version compiled succesfully on a Athlon XP based
machine with ifc7.1 and the ATLAS library. The benchmarks ran without
problems or warnings on this machine.
I am now trying to install it on a dual Opteron246 machine. I use the
PGI-5.1 compiler and the AMD ACML-2.0 math library. I manage to compile to
code, although I get the following warnings from the linker:
/usr/bin/ld: Warning: alignment 16 of symbol `vaspxml_1_' in xml.o is
smaller than 32 in main.o
/usr/bin/ld: Warning: alignment 16 of symbol `main_mpi_0_' in main_mpi.o is
smaller than 32 in main.o
/usr/bin/ld: Warning: alignment 16 of symbol `main_mpi_0_' in main_mpi.o is
smaller than 32 in poscar.o
/usr/bin/ld: Warning: alignment 16 of symbol `vaspxml_1_' in xml.o is
smaller than 32 in ini.o
/usr/bin/ld: Warning: alignment 16 of symbol `asa_0_' in asa.o is smaller
than 32 in radial.o
/usr/bin/ld: Warning: alignment 16 of symbol `mgrid_0_' in mgrid.o is
smaller than 32 in main.o

and a long series of those for all kinds of '.o' files.
I do get a 'vasp' executable out however. But when I to run it on the
'benchmark' case, I get the following WARNING messages, indicating that the
ZHEGV procedure is not found.

Where do those WARNINGS come from? What should I do to get rid of them? Is
the code working ok despite the warnings (I am not experienced with VASP at
all yet)? However I notice the results for ETOTAL are not the same as I got
on the Athlon machine for the same benchmark.
I appended below the Makefiles I used for compiling the vasp.4.lib and
vasp.4.6 on the Opteron246, as well as the end of the OUTCAR file I got from
'benchmark'.
Thanks and regards,

Olivier.

# BLAS must be installed on the machine
# there are several options:
# 1) very slow but works:
# 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.

# 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"

# --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

the warnings ...
WARNING in EDDRMM: call to ZHEGV failed, returncode xxxx
are due to a call to the LAPACK routine ZHEGV in the subroutine which optimizes the trial wavefunctions (RMM-DIIS algorithm, iterative matrix diagonalisation)
to avoid these errors, you could either
1) choose a different version of LAPACK (e.g. the one delivered with the
vasp-package (lapack_double.o in vasp.4.lib) (please don't forget to remove lapack_double.o if it is among the untared files of vasp.4.lib.tar which was retrieved from the ftp server, and re-compile it with the compiler you actually choose to use)
2) use a different algorithm for electronic optimisation:
--) blocked Davidson (ALGO = Normal) is very stable
--) a combination of a few steps of Blocked Davidson first + RMM-DIIS
(ALGO = Fast)
if your errors are caused by a numerical instability, depending on your
specific input(s), these approaches (2) are possibly more stable.
