Dear all,
I tried to run NAMD2.9 by using new GTX-280 but
it did not start properly ( see output below)
Any suggestions?

NAMD command:
..
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$namdhome
$namdhome/namd2 +p4 +idlepoll +devices 0 input.namd > output.out
(same behavior with +devices 1)

NAMD output:
