Hi I have created a small application upon VisAD to display cloud retrieval product. On Windows 2000, the response ( or display update) to domain range or display variable range change or color table is much faster than one on the SGI. The file IO is also very slow on my SGI (195 MHZ IP30 Processor or CPU: MIPS R10000 Processor). (My input data file is about 19MB with 20 2D variables, each variable jhas 700 by 350 pixels ). But on Windows 2000, I always run into the problem " out of video memory" when I have several display window open at sametime or resize the display window. (I have 16MB video memory on my PC). Anyone has any idea on my problem? and how can I solve the performance issue on SGI? Thanks a lot Helen
