Arts & Edu., Yamanashi Univ., Japan X-Newsreader: mnews [version 1.17] 1994-01/27(Thu) Followup-To: comp.lang.fortran Lines: 13 Although I installed f2c on BSD/OS 2.0, they do not work as I expected. My machine is Gateway2000 P5-90, so I expected the performance is about three times faster than Sun IPX as the byte-benchmark3.1 shows. However, it approximately same as the latter. Why? It seems not to use FPU. The major part of my fortran codes is floating-point calculation. My linker options are simply "-lf2c -lm". Help me, please. Thanks, Hiro
