The compiler/optimization flags I use (or am experimenting with are) for
the Linux 64bit Intel XE compilers and R-2.12.2 are:
-O3 -ipo -msse3 -fp-model precise
export AR=xiar # not needed when using -ip
instead of -ipo
#export MAIN_LDFLAGS="-limf -lpthread"
I am using, http://www.rd.dnc.ac.jp/~otsu/lecture/RwithMKL.html to
compile R 2.10 . Everything compiles fine but I was wondering if there
are any more optimizations I can do with the flags.
