Source: scotch Severity: normal We're discussing introducing a 64 bit-build for the computational stack. This refers to 64-bit addressing to cells in meshes, etc.
c.f. Bug#953116 (petsc) Bug#961108 (openmpi) https://lists.debian.org/debian-science/2020/05/msg00051.html BLAS is already 64-bit enabled. For the 64-bit environment to work, it needs to be carried through all along the library stack, from BLAS to PETSc. MUMPS is in the middle. Its docs indicate that its 64-bit support requires SCOTCH to be 64-bit enabled. Probably we want 2 separate builds, 32-bit (the current libmetis-dev) and a separate 64-bit libmetis64-dev. Opening this bug to track the chain of 64-bit package dependencies. -- debian-science-maintainers mailing list [email protected] https://alioth-lists.debian.net/cgi-bin/mailman/listinfo/debian-science-maintainers
