Hello netters. Here are my dumb question(s): 1. i tried to compile a 1650-line Fortran program from a Cyber to model liquid flow. When I tried to pass it through the optimizer with options different than '-O', iropt dumbs core after the occupation of over 8 MBytes (as the 'top' program showed). I tried the following options, to no avail: -O3 -O3 -fsoft (Note: we don't have a 68881) -O -fsoft -O -mc68020 Simple '-O' works fine, but the executable seems rather large (160 K, versus the 56 K of the source. The VAX optimizer emitted only a 80 K executable). Hadware: SUN 3/50, 4Mbytes RAM, CDC 300MB HD (shared among other two 3/50s, no FPU, SunOS 3.5 (EXPORT)) It's something going wrong here? 2. We're going to install SunOS 4.0, but from what I see here in the net, started to fear the presence of many bugs. My fear is serious, because just some days ago we aquired a decade of SUNs with one(or more) servers. Is it a good idea to insist on 3.5 and wait for a more debugged version? Please send e-mail, and I'll summarize. Have a nice day, Nick. -- Nikolaos Fotis e-mail: mcvax!ariadne!theseas!nfotis or (outside Eunet) try nfotis@theseas.UU.NET Home: 16 Esperidon St., Halandri, Athens GREECE, 152 32
