@poulson: it appears that the code is hanging inside of LeastSquares :(
ive seen this before, with OpenBLAS. I think there might be a build problem there.

I doubt that the hang is Elemental-specific
it might be worth checking that the ABI's all matched; hopefully there wasn't a mix-up between 64-bit int and 32-bit int versions

@poulson: I think I see the problem, I think you are right, it looks like the code is reading the matrix in wrong.
reading in row major..

Need to run D&C EVD and DVD at scale at least once before releasing
Colleague at Julich claims something is not working in their driver since I made the switch, but it is a significant possibility that the problem is on their end
