Hi,

 

yesterday I updated NAMD from 2.9 to 2.11. Unfortunately I got the following
Error when trying to run the CUDA enabled Binary on a System with two Quadro
FX3800 graphics cards:

 

FATAL ERROR: CUDA error binding lj table to texture on Pe 2 (ceo-01 device
0): invalid texture reference

Until NAMD 2.9 everything used to work fine.

Testing of NAMD 2.11 with CUDA on a system with two Tesla K20 Cards also
works.

 

System: Linux CentOS 7.2, Nvidia Driver 340.96,

Commandline for Testing (Lysozym-Tutorial): namd2 +idlepoll +p4
ubq_ws_eq.conf > ubq_ws_eq.p4.gpu.log

Graphics Cards: Two Nvidia Quadro FX3800

 

Something must have changed from 2.9 to 2.11 in CUDA Support? Someone any
hints?

 

Regards,

Joachim
