Even on Ubuntu, mine is running on a full desktop environment, GotoBLAS's performance is about 95% using dgemm. dgemm on Linux is lot more stabler than FreeBSD and clearly faster. on Ubuntu $ ./dgemm n: 3000 time : 51.180000 or 12.795519 Mflops : 42216.341930 n: 3100 time : 56.280000 or 14.261719 Mflops : 41791.049205 n: 3200 time : 61.350000 or 15.631380 Mflops : 41939.023080 n: 3300 time : 67.790000 or 17.247202 Mflops : 41685.474166 n: 3400 time : 73.800000 or 18.471321 Mflops : 42569.300032 n: 3500 time : 81.480000 or 20.781936 Mflops : 41273.585044 n: 3600 time : 88.170000 or 22.816965 Mflops : 40907.246233 n: 3700 time : 95.210000 or 23.864101 Mflops : 42462.684969 n: 3800 thanks -- Nakata Maho http://accc.riken.jp/maho/ , http://ja.openoffice.org/ Nakata Maho's PGP public keys: http://accc.riken.jp/maho/maho.pgp.txt _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
