I use --COPTFLAGS="-mavx -mfma4 -O3" --FOPTFLAGS="-mavx -mfma4 -O3" and single-threaded ACML optimized for fma4 instruction set ( i.e. gfortran64_fma4/lib/libacml.a) Obviously, I use gcc and gfortran. All works fine. No need for Intel on this machine. If you think gcc is much slower, just try with optimization. > 1. > > > > -- > ----------------------------------------------------- > Dharmendar Reddy Palle > Graduate Student > Microelectronics Research center, > University of Texas at Austin, > 10100 Burnet Road, Bldg. 160 > MER 2.608F, TX 78758-4445 > e-mail: dharmareddy84 at gmail.com <mailto:dharmareddy84 at gmail.com> > Phone: +1-512-350-9082 > United States of America. > Homepage: https://webspace.utexas.edu/~dpr342 > <https://webspace.utexas.edu/%7Edpr342> -------------- next part -------------- An HTML attachment was scrubbed...
