Hi Christian, AFAICT, PETSc is finding make_new_seed_mpi, and deciding to build with it, right? Oh, but that's one of the very few mpi functions in there, I see.
I'd be happy to disable sprng support in PETSc if it's causing problems. Right now I'm chasing down another problem causing grave bug 529303 (and possibly 529162 in a reverse-depend), so I will probably upload a new version soon. -Adam On Mon, 2009-05-18 at 18:07 +0200, Christophe Prud'homme wrote: > Dirk > > I am not really interested (at the moment) but Petsc 3.0 in Debian is > compiled with sprng support (I CC Adam Powell the maintainer of Petsc) > but Petsc cannot find the proper MPI sprng routine. > > Adam > should we disable sprng support in Petsc ? with this Petsc 3.0 is > still broken in Debian > > Best regards > C. > > On Monday 18 May 2009 16:21:29 Dirk Eddelbuettel wrote: > > On 18 May 2009 at 15:50, Christophe Prud'homme wrote: > > | Package: sprng > > | Severity: wishlist > > | > > | --- Please enter the report below this line. --- > > | Hi Dirk > > | > > | it seems there exists a sprng4 (which uses the > autoconf/automake/libtool) > > | and in debian only sprng2 is available. > > | Moreover it seems that sprng has support for MPI, would it be > possible to > > | add mpi support ? > > | > > | Unfortunately sprng has not been updated wrt recent version of g++ > (4.3 > > | and 4.4) > > > > sprng is, politely speaking, a mess. > > > > I forced my way around sprng2 with some help from others (to make it > create > > a shared library) as I needed a distributed random number generator > for use > > by R with the snow (r-cran-snow) framework for distributed > computing.
