Bug#1086242: petsc: version of petsc --with-64-bit-blas-indices ?

[Giacomo Mulas]

Source: petsc
Version: petsc library compiled --with-64-bit-blas-indices
Severity: wishlist

Dear Maintainers,

as a computational scientist, I develop codes that need to use petsc, slepc, _and_ lapack/blas with 64 bit indices simultaneously. As a result, I currently have to compile my custom version of petsc and slepc enabling the --with-64-bit-blas-indices option. Since now 64-bit indices versions of lapack, blas, and scalapack are packaged in debian, it would be feasible and awesome if you could also provide a debian packaged version of petsc compiled with the --with-64-bit-blas-indices option enabled. it would actually be _relatively_ easy, since you already provide the "64" versions compiled with the --with-64-bit-indices option enabled.

Thanks for all the great work, best regards

Best regards, bye
Giacomo Mulas
