I'm trying to optimize my Fortran program and used `time` to compare
speed between different versions of the same Fortran program.
But I don't understand the output from `time`, and don't know which
number here is the best indicator of efficiency.
here is the output.
(the machine is a SGI with 8 150MHz processors running IRIX 188.8.131.52)
nic 12% time fprog.1
441.5u 5.7s 7:46 95% 0+0k 19+2io 13pf+0w
nic 13% time fprog.2
501.1u 4.8s 8:45 96% 0+0k 15+2io 20pf+0w
nic 14% time fprog.3
949.6u 8.2s 16:36 96% 0+0k 52+15io 47pf+0w
Can anyone enlight me on this, please. What does each number mean?
Thanks for any help.
