Dear Suhaib, Thank you very much for your info.
However, my situation is that we already have a machine (RS6000), and we want to upgrade some hardware (or software if that is a bottle neck) to improve performance. I took a look at nVIDA's site, and it seems like the chip runs only on Intel compatible CPU. Are you aware of similar product which runs on RS6000? Also, is 128MB of RAM for the one attached directly to CPU? This is less than the RAM of our current system. Does this mean memory is not that critical for visualization? Our data file is typically tens of MB. When we animate it, dx sometimes aborts saying that there is not enough memory, so we have to make the size of file smaller by selecting fewer number of data at each grid cell (our data is multi-valued, up to ~30 variables). This is another source of frustration. Is there any recommendation for this as well? yosuke kimura On Fri, 12 May 2000, Suhaib Siddiqi wrote: > If you want to spend money and get Linux box, you might consider > getting a PC with nVidia GeForce2 with 128 MB RAM. nVidia provides > hardware accelerated OpenGL and kernel drivers for their GeForce family > cards.
