Hi,
If you have two GTX 590-s four devices should show up in nvidia-smi and
mdrun should also show four devices detected. As nvidia-smi shows only two
GPUs means that one of your cards is not functioning properly.
You can try to check what GPU devices does you operating system "see"
independently form the driver using the lspci command, e.g:
lspci | grep -i ".*VGA.*NVIDIA.*"
If you see two PCI devices in this output that means that both cards are
detected by the operating system. If nvidia-smi does not show all four
GPUs, there must be something wrong with your driver.
