One of our researchers would like to use the timing routines in one of his programs using C++. He has gotten it to work using regular C code but whenever he tries to use it in C++ the program bounces despite compiling without any error. The routine he is using is MPI_Wtime(). I would appreciate if somebody could give me a clou on how to incorporate a timing call into C++ parallel code. Maybe by sending me a small sample code where the timing routine is implemented. Your help is greatly appreciated. Thanks a lot in advance Rainer ------------------------------------------------------------------------------ Rainer Echle, Ph.D. | E-Mail: rainer@unix1.sncc.lsu.edu High Performance Support Group | rainer@lsu.edu Office of Computing Services | Louisiana State University | Ph: (504) 388-6766 Baton Rouge LA 70893 | Fax: (504) 388-1978 ------------------------------------------------------------------------------ "The above expressed opinion is solely my own and does not express or represent in any way the opinion of my employer." -----------------------------------------------------------------------------
