TAPENADE

Summary:
TAPENADE is a source-to-source AD tool. Given a FORTRAN77, FORTRAN95,
or C source program, it generates its derivative in forward (tangent) or
reverse (adjoint) mode. TAPENADE is the successor of ODYSSEE.
TAPENADE is directly accessible through a web servlet, or can be downloaded locally.
