# 
# MAKEFILE FOR GNU/Linux SPIDER using FFTW on 2 or more processors --
# For: 32 bit Pentium4 Xeon (Should also run on 64 bit Intel OK)
# 
# Note:  To create executable: make -f Makefile_linux_mpfftw_intel
#
# Using: Portland Group F90 compiler
#        Non-native mode byte ordering on:  Intel IA32 GNU/Linux 
#        FFTW must be configured with:  --enable-float  --enable-type-prefix
#        We use FFTW without threads as it is usually slower using threads for
#        multiple processors in our testing (June 05 al)
#
# All libraries are statically linked except libm, glibc & libpthread.
#
# Note:    You may ignore any undefined QFFLAGS, QLFLAGS & SUFFIX

# -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
# -Mipa=fast     : Invokes interprocedural analysis (some routines 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
#-mcmodel=medium : Allows use of >2GB data area on 64 bit machines
#-mp=nonuma      : No numa library for Intel??
