Hi Jim:
No hurry more, and sorry for that my unusual request. I'll buy two new
GTX-580, should the procedure I used for the GTX-680 be correct and
the time requested for tuning the code for the GTX-680 will prove to
be considerable.

thanks

Hi Jim:

My attempts at running namd-cuda 2.9, nightly build 2012-06-20, on
GTX-680 failed. I used the same procedure as with my previous Gigabyte
890FXA / AMD Phenom II / two  GTX-580. The latter had no problems, and
i tried now to continue the already advanced equilibration of a
protein in a water box, carried out under parm7 ff.

HARDWARE: Gigabyte X79-UD3 , Intel i7-3930k, two GTX-680 on x16 lanes.

OS: Debian amd64 wheezy (testing), cuda driver 295.53-1.

COMMANDS:
- nvidia-smi -L
GPU 0: GeForce GTX 680 (UUID: N/A)
GPU 1 : as above

-nvidia-smi -pm 1
Enabled persistence mode for GPU 0000:02:00.0.

-charmrun $NAMD_HOME/bin/namd2 xxx.conf +p6 +idlepoll 2>&1 | tee xxx.log

The log file tells;

*************

Would it be safe not to sell the GTX-580  and set aside the GTX-680
for the future? Oor is anything that can be changed in my procedure? i
am not a pessimist, just I am still in time to take the GTX-580 back
from the vendor where I did the business.

Thanks a lot for advising me with urgency (because of the said
business, and I beg pardon very much for asking urgency)
