TAMC
Summary:
TAMC is a sourcetosource ADtool for FORTRAN77 programs. The generated code propagates derivatives in forward (tangent linear) or reverse (adjoint) mode. TAMC is very flexible thanks to many options and user directives.

Features:
 Fortran 77 Support:
 TAMC supports almost the full FORTRAN77 standard and also some common extenstions.
 Fortran 90 Support:
 Some Fortran90 extensions to FORTRAN77 are supported.
Array assignments and WHERE statements are supported.
Most intrinsic functions are handled.
 Analysises:
 TAMC normalizes the code and applies a control flow analysis.
TAMC applies an intraprocedural data dependence
and an interprocedural data flow analysis.
Given the independent and dependent variables
of the specified toplevel routine,
TAMC determines all active routines and variables
and produces derivative code only for those.
 Directives
 TAMC accepts several directives.
Using the reverse mode storing of variables instead of recomputation
is controlled by directives.
Multi level checkpointing can be implemented by splitting
a loop and inserting directives.
Black box (library) routines are handled using flow information
given by directives.
Supported Platforms:
 Application Server
Licensing: free with restrictions
