Sasha,
Thank you for your reply!
The protein I am simulating is quite small, so I did not see the error
that you are experiencing. If you could send me your script and
prmtop/inpcrd file, I will try it on our machine.
BTW, my card information:
Product Name : GeForce GTX 480
PCI ID : 6c010de
And the cuda driver version is 3.1
Cheers,
Yi
