Dear PyMOL users, We are using an old SGI (O2) classroom for teaching in a client/server setup in which compute-intensive modeling programs run on a few fast servers but display on slow SGI terminals. This works fine with some applications but PyMOL obviously recognizes SGI OpenGL setup and will use this for rendering, which makes things rather slow. Is there a way to redirect PyMOL to use server's CPU for some of the tasks, such as calculating the surfaces? Thanks in advance,=20 Kalju =20 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Dr. Kalju Kahn Department of Chemistry and Biochemistry University of California, Santa Barbara |

Kalju, 1. Old SGIs have pitiful graphics performance when compared to modern PC graphics cards. You would likely get better results running PyMOL locally on a PC desktop or laptop than on an old SGI workstation. 2. Surfaces are calculated server-side, however, PyMOL was not optimized for client/server setups. set use_display_lists, 1 might help a bit when displaying surfaces and other complex geometries. -- DeLano Scientific LLC Subscriber Support Services mailto:de...@de...
