Re^4: Tesla c2050


Hi, Dr. Granovsky, sorry for the late reply.

We just finished large MD simulation, and we totally ready to start FF8 calculations.

I first step we run simple input file. Firefly8 correctly detect all tesla card and run calculation, but after several steps, calculation froze without any error messages (see attach).  

Regards, Gadiev Radik
