# Makefile for Intel Fortran compiler for P4 systems
#
# The makefile was tested only under Linux on Intel platforms
# (Suse 5.3- Suse 9.0)
# 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)
# 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:
# 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
#
# 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.
# If you want to use atlas based BLAS, check the lines around LIB=
#
# 3c) mindblowing fast SSE2 (4 GFlops on P4, 2.53 GHz)
# Kazushige Goto's BLAS

# RPROMU_DGEMV use DGEMV instead of DGEMM in RPRO (depends on used BLAS)

# the following lines specify the position of BLAS and LAPACK

# Atlas based libraries
#ATLASHOME= /udata/zxhu/opt/Linux_P4SSE2/lib
#BLAS= -L$(ATLASHOME) -lf77blas -latlas
# use specific libraries (default library path might point to other libraries)
#BLAS= $(ATLASHOME)/libf77blas.a $(ATLASHOME)/libatlas.a
# use the mkl Intel libraries for p4 (www.intel.com)
# mkl.5.1
# set -DRPROMU_DGEMV -DRACCMU_DGEMV in the CPP lines
BLAS= -L/udata/zxhu/opt/intel/composer_xe_2011_sp1.6.233/mkl/lib/intel64 -lmkl_intel_lp64 -lpthread -lmkl_core -lmkl_sequential
# mkl.5.2 requires also to -lguide library
# set -DRPROMU_DGEMV -DRACCMU_DGEMV in the CPP lines
#BLAS=-L/opt/intel/mkl/lib/32 -lmkl_p4 -lguide -lpthread
# even faster Kazushige Goto's BLAS
