Description

Many applications use an internal memory pool (scratch space). It would be great if this allocated memory could be recycled by SUNDIALS (e.g. for storing the Krylov basis array etc.) to lower the overall memory footprint.

Research direction

The issue does not mention any files, tests, or entry points. Begin by locating SUNDIALS memory-allocation and Krylov-basis handling, then determine the interface needed for applications to provide a scratch pool. Done means user-provided scratch memory can be recycled for internal allocations and the overall memory footprint is reduced.
