Hi Gregory,
I am not very familiar with the could computing offerings, but as far
as I know, in general they are not a very cheap solution when it comes
to relatively low usage (non massive enterprise use).
If you would need it only for you own research, you might be better
off with applying for a grant to get cluster time at a compute center.
Alternatively, as the next Gromacs version will support GPU
acceleration and will have quite with decent performance, you could
consider investing in multi-GPU box with GeForce cards. Of course,
this is feasible only if you don't mind the maintenance overhead and
costs.
Cheers,

Radeons work as well. You can put a 3-4 GPU board together with the highest
end AMD or Intel chip for 3K, plus 16G RAM if you look around for a day or two,
but the cooling is the main problem (with 1/4 the price radeons Vs. GTI cards),
so one has to take cooling into account (h20 cost another 800$, or investing in
4-6 good fans/cooling an additional 2-300$). If you have a slightly higher
budget you can get multi CPU boards with 4 GPU slots, ie 4 or 8 CPU's (direct
via mail from Taiwan), but the CPU's and GPU's is where the money is spent.
As far as I have seen GPU Gromacs runs at around 1 Teraflop per Radeon 5900
series (double percission, single is supposed to run around 4 tera flops per
GPU, so depends on your needs, desires as far as simulations), and the latest
Intel 970's are around 400-500 Gflops/chip.
