Has anyone out there While I work for a unix house, and do encourage its use .... Moving from VMS to Ultrix tends to result in: 1) Lower machine performance (more users can share a vax running vms than ultrix ... in my experience) 2) VMS debugger and fortran environment is better (tracebacks automatically, etc). 3) More robust On the plus side for ultrix ... is it looks more like unix ... and is better suited for use in a mixed vendor environment. You may wish to consider sysV or bsd for your vax ... I have used all three and both the sysV and bsd stuff was closer to the other vendors stuff (not suns, btw). Plus for ultrix is that now that DEC has signed up to do RISC (via MIPS) Ultrix probably has better support than the third party offerings. As for the 205 replacement ... if you can wait until 2nd QTR next year PRISMA claims that their 100Mflop SPARC machine (sunos, sun4 binary compatible) mainframe should be out before then (public date is first hw jan 1990 ... my guess is that one has to wait a few months from first hw to first shipment :>). Won't have all those nifty vector instructions, but 100mflops scalar is respectible (and price will probably be about $1million). Of course, all the opinons are mine and are not endorsed by anyone. cheers -- Keith H. Bierman |*My thoughts are my own.
