Feature/cg reliable update
2017-09-21 10:12:03 +01:00
b83b2b1415 Stability improvement to BCG. Force m_rr hermitian beyond rounding. 2017-09-04 14:09:47 +01:00
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?

41f73ec083 Add ChronoForecast class for forecasting solutions across poles in the EOFA heatbath 2017-08-16 12:37:38 -04:00
9939b267d2 Added switching to fallback linear operator in reliable update CG, and added recalculation of b parameter on update. 2017-07-31 13:39:44 -04:00

e504260f3d Able to run a test job splitting into multiple MPI subdomains. 2017-06-22 18:53:11 +01:00
b9104f3072 Block CG 2017-06-21 21:08:03 +01:00
e8b95bd35b Clean up finished. Could shrink Lanczos to around 400 lines at a push 2017-06-21 02:50:09 +01:00
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

0486ff8e79 Improved the lancos 2017-06-20 18:46:01 +01:00
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.

8e161152e4 MultiRHS solver improvements with slice operations moved into lattice and sped up.
Block solver requires a lot of performance work.
