Please remind us of this when you write. We don't know everyone in your group at Purdue and it would simplify our figuring out what could cause the weird problems you encounter. > And in that case, when the second PETSc library is initialized, > cudaSetDevice throws an error.

This is a general issue of interoperability between multiple libraries that want to use CUDA. How can we find out if someone else has already called cudaSetDevice?
