Summary:PaStiX solves a 3D problem of 45 millions unknowns
Project:PaStiX

The direct solver PaStiX has been successfully used by CEA/CESTA to solve a symmetric complex sparse linear system arising from a 3D electromagnetism code with more than 45 millions unknowns on the TERA-10 CEA supercomputer.
Solving this system required about 1.4 Petaflops (in double precision) and the task was
completed in about half an hour on 2048 processors.
To our knowledge a system of this size and this kind has never been solved by a direct solver.
