can anyone out there help me compare a mac to a 386 clone
w.r.t. floating point performance in fortran?
i have a friend who's a grad student in physics and would
like to buy a machine to run simulations written in fortran.
because of the student discounts available to him, he can
purchase a mac se/30 or a similarly-configured 33 Mhz 386
clone with a 387 math coprocessor for roughly the same price.
i have two sets of questions:
1) what fortran compilers are available for these two machines
at fairly low cost?
how do they perform on the above-mentioned hardware?
2) the 33MHz 386 machine is closest to the se/30 in price,
but slower ones are available. some of these models are
available with and without caches. does presence or absence
of a cache affect math coprocessor performance the same way
it affects performance of other cpu operations?
*** SINCE I DON'T READ THESE TWO NEWS GROUPS, PLEASE MAIL REPLIES
*** DIRECTLY TO ME, AND I'LL SUMMARIZE.
thanks.
