In most of the applications the TLM computes the product of Jacobian times one vector. Whereever there is more than one vector we print: CPU time ratio / # of vectors.
The entry "Yes" means that there is a TLM, but we don't have the performance, whereas "-" means that there is no TLM.
In all examples the CPU time for the derivative of a scalar valued function is given.
Note that a 2 level checkpointing scheme (see, e.g. Giering and Kaminski, 2002) consumes the CPU time of about one additional function evaluation. For example the adjoint of IMBETHY has a CPU time ratio of about 3.6 - 1 = 2.6 for short integrations, which do not require a checkpointing scheme. 3 level checkpointing costs two additional function evaluations.
If the number of columns is not equal one, we print: CPU time ratio / # of columns.
"-" means that there is no Hessian code.
