There is already a machine connected to the quad buffered display with a quadro card which works fine. The customer is a university who is purchasing a cluster from us and would like to use Virtual GL to directly view datasets from one of the cluster nodes. This would have direct access to the large and fast parallel scratch filesystem and would avoid the need to copy all the data out over ethernet to the local storage in the node which can take a long time and could easily just not fit. > On 3/10/15 5:26 AM, Antony Cleave wrote: >> Thanks for this, looking at the options it looks like for stereo we are >> indeed stuck with the Quadro cards.
