Reverse Time Migration with Optimal Checkpointing
Symes, William W.
The optimal checkpointing algorithm (Griewank and Walther, 2000) minimizes the computational complexity of the adjoint state method. Applied to reverse time migration, optimal checkpointing eliminates (or at least drastically reduces) the need for disk i/o, which is quite extensive in more straightforward implementations. This paper describes optimal checkpointing in a form which applies both to reverse time migration and to other applications of the adjoint state method, such as construction of velocity updates from prestack wave equation migration.
