Message-ID: <666@t4test.UUCP> Date: Thu, 21-Jun-84 02:52:57 EDT Article-I.D.: t4test.666 Posted: Thu Jun 21 02:52:57 1984 Date-Received: Fri, 22-Jun-84 04:07:45 EDT References: <290@oddjob.UChicago.UUCP> Organization: Intel, Santa Clara, Ca. Lines: 40 === REFERENCED ARTICLE ============================================= From: sean@oddjob.UChicago.UUCP (Sean Casey) A discussion arose the other day about the relative advantages of running Unix vs. VMS on a Vax 11/750. I'm interested in knowing the consensus among net users (ignoring obvious selection effects.) Arguments in favor of VMS were... o FORTRAN runs faster under VMS (I don't know how FORTRAN under VMS compares to C under Unix??) o VMS runs faster than Unix in a multiuser environment. o One can always run a Unix emulator under VMS for those users who prefer Unix. (Why is there no VMS emulator under Unix?) ==================================================================== People buy computers to run software, not to play with the operating system. (While I like to play, I don't shell out the bucks.) There is a hell of a lot of software developed to run in a VMS environment. All of the test program compilers we use are VMS based. Therefore, in spite of which runs faster, is nicer, etc. we *need* VMS. However, Unix is certainly a very nice environment for development, so we are running Eunice in an attempt to get the best of both worlds. If Unix had the developed software base which VMS does, then maybe there would be a call for VMS emulators under Unix. Maybe someday Unix will it. From what I hear from our test vendors, the world is beginning to discover Unix. Until that time VMS will be a requirement for one and only one reason: it is the only thing which does the job we need to do. Until you address this, you can't even begin to address the other factors. -- Chip Rosenthal, Intel/Santa Clara {idi|intelca|icalqa|imcgpe|kremvax|qubix|ucscc}!t4test!{chip|news}
