LANS Informal Seminar
"Cheaper Adjoints by Inversion"

DATE: May 2, 2007
TIME: 3:00 pm
SPEAKER: Jean Utke, MCS
LOCATION: Building 221, A-261, Argonne National Laboratory
HOST: Sven Leyffer

Description:
A large portion of the "tape" required to do an adjoint sweep in AD is occupied by information related to address computations and control flow decisions. Bulky "tapes" impede the performance of the adjoint code. We will look at a new approach to reduce the memory requirements that relies in part on inversion and re-computation.
