Podium Discussion
- Francesco Giacomo Knechtli (Bergische Universitaet Wuppertal (DE))
Some selected questions:Critical slowing down with $a\to 0$.
- Rounding issues on large volumes.
- Multiscale approaches to increase signal over noise
- Benefits of (approximate eigenvectors) and how to obtain these
- Approaches to excited state contributions: multi-state fits, GEVP, smearing.
- efficient stochastic estimation of traces, all-to-all propagators, perambulators
These are...
The following questions emerged from an e-mail discussion with Gustavo Ramirez:
1) Deflation (with approximate projection) as a multigrid method seems tricky to be ported to GPU architectures in an efficient way.
2) Can one understand why ? Is that solely due to the poor scalability of the 'little Dirac operator' ?
3) Isn't that then a general problem for multigrid methods on GPU ?...
