[gmx-users] low performance 2 GTX 980+ Intel CPU Core i7-5930K 3.5 GHz (2011-3)

[Carlos Navarro Retamal]

Dear gromacs users,
I just found that i installed a old version of CUDA https://developer.nvidia.com/cuda-downloads
Instead of a new one for my graphic cards.  
https://developer.nvidia.com/cuda-downloads-geforce-gtx9xx
Do you think that this can be the problem?

 In any case i’ll install the new tool kit and compile gromacs again.
Best regards,
Carlos
