# MAKEFILE FOR GNU/Linux SPIDER using FFTW3 on 2 or more processors on Opteron 64--
# 
# Note:  To create executable: make -f Makefile_linux_mpfftw3_opt64
#
# Using: Portland Group F90 compiler
#        Non-native mode byte ordering on:  AMD Opteron GNU/Linux 64 bit OS
#        FFTW must be configured with: --enable-float --enable-type-prefix

# -O2             : Invokes level 2 optimization (-O3 causes some run time problems with PGI compiler on SPIDER code)
# -mp             : Invokes multi processor support
# -tp p6          : Targets 32 bit Pentium Pro/II/III with 32 bit memory addresses, supports x87 FP
# -tp p7          : Targets 32 or 64 bit Pentium4 with 32 bit memory addresses, supports SSE1 & SSE2 FP
# -tp p7-64       : Targets 64 bit Pentium4 with 64 bit memory addresses, supports SSE1, SSE2 & SSE3 FP
# -tp x64         : Targets unified 64 bit AMD & Intel binaries (samoa)
# -tp k8-64e      : Targets AMD Opteron Revision E or AMD Turion (cluster)
