Stefano: Thanks for sending us the patch. Is this for petsc-3.3 or petsc-dev? I'll test the patch first, then push to the repository.
Yesterday it was the first time I try to build a single-precision version > of PETSc with some external packages. > I noticed that SuperLU and MUMPS, which are currently fully compiled (i.e. > with scalar types s,d,c and z) by the configure, cannot be used when > requiring single precision at configure time. So I decided to wrote a patch > to enable their use when PETSC_USE_REAL_SINGLE is defined. > > Attached please find a patch. Is there any reason for which you did not > already provide this functionality? > No user has ever requested single precision for these external packages. > I tested the patch on BlueGene/Q and it works for scalar types real. > Currently, I don't have a complex version of PETSc installed. Can someone > test it? > I'll test it. > > I also noticed that UMFPACK (which itself does not have support for single > precision), is accepted by the configure by requiring > --with-precision=single --download-umfpack=1. Is it normal? It breaks the > final linking of the executables. > This might be a bug in petsc. I'll check it. Hong -------------- next part -------------- An HTML attachment was scrubbed...
