Hi all，
I just installed Amber20 on my computer with two Nvidia tesla C2050 cards.
The operation system is Unbuntu 18.04. And the Cuda version is 9.0. No error
information was reported during installation and compile processes.However,
when I tried to run pmemd.cuda, I got an error message:
"Error searching for compatible GPU."
Here is the output file:
| PMEMD implementation of SANDER, Release 18

The nvidia-smi showed that there are two C2050 cards in the computer:

I am wondering that if someone know how to fix this problem?
Thank you very much!
