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.

Bug#529295: [sprng] sprng4 and mpi support
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.

Yup, it's disabled in my current build. Will upload when I finish testing. So is the following a concise summary sprng2 available in debian, and used by r-cran-rsprng But built without MPI. sprng4 _not yet_ available in debian, but possibly useful for PetSc ? I.e. no overlap? As I understand the sprong website, versions 2 and 4 are not plug-and-play. So if you guys have use of for sprng _version 4_ you may just have to package it, no?I could then try to port the R package forward and we could all get rid of the old sprng2 Actually, PETSc's linkage is made for version 1 (made some changes to try to support version 2), so we shouldn't be a factor in this decision. I wanted to do some RNG stuff and added the link, but it seems that was misguided. -Adam -- GPG fingerprint: D54D 1AEE B11C CE9B A02B C5DD 526F 01E8 564E E4B6 Engineering consulting with open source tools http://www.opennovation.com/ signature.asc Description: This is a digitally signed message part
