Both the SPARCstations were running SunOS 4.1.1 Beta while the 4/490 was running SunOS 4.1. The compilers used were Sun's FORTRAN 1.3.1 and the Sun C compiler bundled with SunOS 4.1.1 Beta. The "-Bstatic" option was used in all cases to insure compile time (static) linking with libraries. The optimization levels used were (0) no optimization; (1) level 1 (-O1); (2) level 2 (-O2); and (3) level 3 (-O3). The C compiler was used only to compile a module encapsulating the SunOS times() system call for measurement of (user) time. This C module and its FORTRAN interface, second.f, which defines the second() function in the linpack programs, were supplied by Paul Hansen, and are included below. Results are based on the last of three consecutive executions of each appropriately compiled linpack program the output of which is also included below. Oddly enough the (arithmetic) average of the single and double precision Mflops for the SPARCstation 2 at level 3 optimization is 4.2, which is exactly what Sun claims it to be in SunFLASH Vol 23 #6, "SPARCstation 2 Family," November 1990 (distributed via email from Sun).
