# MAKEFILE FOR GNU/Linux SPIDER using FFTW on 2 or more processors  Intel/AMD 32 bit
# FOR:  Intel/AMD IA32 GNU/Linux 
# 
# Note:  To create executable use: make -f Makefile_linux_mpfftw 
#
# Using: Portland Group F90 compiler
#        Non-native mode byte ordering on:  Intel/AMD IA32 GNU/Linux 
#        FFTW3 must be configured with: --enable-float --enable-type-prefix
#        Use FFTW3 with OMP threads
#
# Note:    You may ignore any undefined: QFFLAGS, QLFLAGS, or SUFFIX

# O3 seems to cause some problems with PGI compiler on SPIDER code
# -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
# -Mipa=fast     : Invokes interprocedural analysis (some routines may fail to compile)
# -fast          : Selects an appropriate set of optimization flags usually including -O2 -Munroll -Mnoframe
# -fastsse       : Selects an appropriate set of flags including SSE support usually including -O2 -Munroll -Mnoframe -Mvect=sse -Mcache_align 
# -pc 64         : Sets precision of FPU operations
