Hi Ross:
Will older NVIDIA GPUs be supported in a multi-GPU version of Amber? I
am thinking about C1060, etc. It could be useful to use established GPUs
for 1-2 years until NVIDIA improves and matures Fermi architecture.

Just to update on this... We hope to have a multi-GPU version of AMBER
ready
in a few months. EXTREMELY provisional numbers are on the order of
2.5-2.7
or so times speed up on 4 C2050's (vs 1 C2050) using 4 GPUs for JAC.
This
will hopefully be released as a patch to the AMBER 11 code once it is
finished and has been tested.
All the best
Ross
