I am rather happy with my DN10K as a high end cruncher (especially with recent performance improvements in the vector library, about which I will say more some other time), but we will need to be buying a rather large number of individual workstations in the next few years. The path of least resistance for these is the SparcStation, but I would like to hear other opinions, specifically on how the 400t series stacks up against it with regard to: --Price of a color system --Graphics capabilities --Availability and price of third party memory, magnetic disks, and magneto-optical disks --floating point performance --availability of "ready to make" public domain software, like the NCSA stuff --quality, price and availability of commercial software for graphics, numerical analysis, database handling (of databases of images and 3D flow fields) --graphical user interface and class library support (in c++?) for building relatively portable user interfaces. In short, the question is why should I buy 400t's rather than Sparcs? I have an open mind, but if the argument is only that 400t's are "as good" that won't cut it, as we are more familiar with Sun equipment, so the sparcs have no learning curve and it is easier for us to get help. The 400t's have to offer substantial benefits over a Sparc. Unfair, perhaps, but there it is. As far as I can see, with OSF/Motif, the user interface issue is the most compelling advantantage of the 400t's, given that OSF probably won't be ported to Sparcs (or will it?). Happy to hear from HP/Ap marketing types as well as technically oriented users. We run straight BSD unix plus NFS, so the ability to run Domain is not an issue. Also, we don't have much need for fancy source code control systems. We do fluid dynamics related to global climate modeling, and analysis of massive databases of flow data and satellite data.
