Dear folks I've managed to compile the gpu-version of QE gently provided by Filippo Spiga. However, the gpu card I've got (Titan X, Pascal architecture) has 11 gb of global memory so it goes easily out of memory when I try to simulate a medium system (say ~80 atoms) or at least these are the messages I obtain when running those jobs.
Thus, I've got two questions concerning the use of gpu cards with QE: 1) What gpu cards are you using for serious runs/research? How much global memory do they have? I've recently learnt that the Quatro P6000 model has about 24 GB of global memory but it costs about 5000 euros. 2) Does it make sense to combine more than one gpu card on one mother board? That is, is global memory additive in such cases? Sorry if this question is non-sense, I'm a newbie in gpu stuff. Thanks in advance.
