d9cd4f0273 Staggered multinode block cg debugged. Missing global sum.
Code stalls and resumes on KNL at cambridge. Curious.

CG iterations 23ms each, then 3200 ms pauses. Mean bandwidth reports
as 200MB/s. Comms dominant in the report. However, the time behaviour suggests it
is *bursty*.... Could be swap to disk?

dee68fc728 IO working multiple nodes again. Strategy of all nodes writing metadata is unsafe.
Only one rank should do this. must identify this rank. Means pass communicator to the
Objects.

7e35286860 Simplified lanczos, added Eigen diagonalisation.
Curious if we can deprecate dependencly on BLAS.
Will see when we get 48^3 running on our BG/Q port

e9cc21900f Block solver complete for staggered. Now stable on mass 0.003 and
gives 8x (!) speed up on Haswell laptop vs. standard CG for 8 RHS solves.

166 iterations vs. 537 iterations so algorithmic gain + 2x in flop rate gain.

Better than a slap in the face with a wet kipper.
