Sorry, I should be more clear. The system has 3 servers which are HP xw8600 workstations ( http://h20331.www2.hp.com/Hpsub/downloads/xw8600_xw6600_FAQ_hi_res.pdf). Each of them has 1 gpu (nvidia quadro fx 5600 with 2 dvi connectors). There is only one cluster. Sorry about the confusion.
I run 2 process for each gpu to achieve tiled display. 2011/8/26 Moreland, Kenneth <[email protected]> > Sorry, but I'm confused by the question. > > You say you have a display comprising 6 screens.
