I am attempting to compile some inhouse code using gcc48 under FreeBSD 9.3R. The man page describes in detail how to get it to produce multi-threaded parallel code (-apo under SGI IRIX (snif), -parallel under icc/ifort). When I add those options to my makefile & try to use them to compile my code, I get the following: gcc48 -DNDEBUG -DUNDER_SCORE_SYS -DLOSE_GAMMAL -I../include -I~/inc -I../Properties -I../TEST -I../pre -march=opteron -mtune=opteron -O3 -floop-strip-mine -floop-blo ck -fprefetch-loop-arrays -floop-parallelize-all -ftree-parallelize-loops=4 -fopt-info -c mpi.c mpprime.c mpi.c:1:0: sorry, unimplemented: Graphite loop optimizations cannot be used (-fgraphite, -fgraphite-identity, -floop-block, -floop-interchange, -floop-strip-mine, -fl oop-parallelize-all, and -ftree-loop-linear) /* ^ mpprime.c:1:0: sorry, unimplemented: Graphite loop optimizations cannot be used (-fgraphite, -fgraphite-identity, -floop-block, -floop-interchange, -floop-strip-mine, -floop-parallelize-all, and -ftree-loop-linear) /* ^ *** [../lib/R4/opteron/libmpi.a] Error code 1 1 error `usual' not remade because of errors. for each 'arch' tried (opteron, barcelone, etc.). How do I find out how to get my gcc48 to use those optimizations ? TIA & have a good one. -- William A.
