# Makefile for Intel Fortran compiler for Pentium/Athlon/Opteron

# based systems
# we recommend this makefile for both Intel as well as AMD systems
# for AMD based systems appropriate BLAS (libgoto) and fftw libraries are
# however mandatory (whereas they are optional for Intel platforms)
# For Athlon we recommend
#  ) to link against libgoto (and mkl as a backup for missing routines)
#  ) odd enough link in libfftw3xf_intel.a (fftw interface for mkl)
# feedback is greatly appreciated
#
# The makefile was tested only under Linux on Intel and AMD platforms
# the following compiler versions have been tested:
#  - ifc.7.1  works stable somewhat slow but reliably
#  - ifc.8.1  fails to compile the code properly
#  - ifc.9.1  recommended (both for 32 and 64 bit)
#  - ifc.10.1 partially recommended (both for 32 and 64 bit)
#             tested build 20080312 Package ID: l_fc_p_10.1.015
#             the gamma only mpi version can not be compiles
#             using ifc.10.1
#  - ifc.11.1 partially recommended (some problems with Gamma only and intel fftw)
#             Build 20090630 Package ID: l_cprof_p_11.1.046
#  - ifort.12.1 strongly recommended (we use this to compile vasp)
#             Version 12.1.5.339 Build 20120612
#
# it might be required to change some of library path ways, since
# LINUX installations 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) more desirable: get an optimized BLAS
#
# the two most reliable packages around are presently:
# 2a) Intels own optimised BLAS (PIII, P4, PD, PC2, Itanium)
#     http://developer.intel.com/software/products/mkl/
#   this is really excellent, if you use Intel CPU's
#
# 2b) probably fastest SSE2 (4 GFlops on P4, 2.53 GHz, 16 GFlops PD,
#     around 30 GFlops on Quad core)
#   Kazushige Goto's BLAS
