"Address Error " with MPI

344 Views

I'm trying to run a weather forecast model on a dual Xeon with RH8, ifc 7.1 and mpich 1.2.5.2 (with the ch_shmem device). When I compile the model with "-O0 -autodouble", it dies with an "Address Error", When I add "-d1" to the compiler options, it runs fine. What else is "-d" doing besides disabling optimization?

BTW - the same model runs fine with the pgi and lahey compilers (with full optimization).
