Carol,
The 15 year old PETSc/Sundials interface fully supports the current PETSc
threading capabilities “for free”; nothing needs to be done on the Sundial side
for threads to be usable in the PETSc vector and preconditioner operations
:-). Presumably this would be true for any other package which uses threads in
its linear algebra that interfaces into Sundials as PETSc does.Barry
