#1700: Use 64-bit integers when building PETSc -----------------------------------+---------------------------------------- Reporter: eschnett | Owner: Type: enhancement | Status: new Priority: major | Milestone: Component: EinsteinToolkit thorn | Version: development version Keywords: | -----------------------------------+---------------------------------------- PETSc needs to be able to count up to the total (global) number of points it uses, not just process-local points. 32-bit integers are not sufficient for large runs. Note that e.g. Carpet already uses 64-bits integers for the same reason.
I suggest to enable the respective option when building PETSc by default. TATPETSc supports this, other thorns may need to be updated.
