Latif -

I have managed to build an executable for sedov 3d with 16^3 blocks with 
intel 10.1, -mcmodel=medium and -shared-intel, following Chris' 
suggestion. I did not include an io module as I do not have hdf5 build 
for a non-default mcmodel.

For 2,000 blocks the executable is about 4.8 GB in size. Even for 1,000 
blocks it is still 2.4 GB. The memory demand would increase still more 
if hdf5 is added.

I doubt you can efficiently use any of those execs on your system. I 
expect lots of swapping action.
