Multi-grid Lanczos


  • Christoph LEHNER

Primary authors



I present a multi-grid Lanczos algorithm that reduces the memory requirements both on disk and in working memory by one order of magnitude for RBC/UKQCD's 48I and 64I ensembles at the physical pion mass. The precision of the resulting eigenvectors is on par with exact deflation.
