Configure figures these out already and can write them to a file as part of installation. Are type sizes not encoded in datatypes #define anyways?

You want me to detect where the mpich installation is? The process manager is separate from the mpich installation. It can be installed separately, and at a different location. It has no idea where mpich is installed, or even if it’s mpich that it is interacting with. Also, you want me to write things to a file and read them from all over the place? Also, note that type sizes are not all. You need the datatype layout as well. Finally, suppose we run a program to generate this file. How do we ship it around? Scp? stdout? This solution is gross beyond imagination. I’m not going to debate about it. — Pavan -- Pavan Balaji http://www.mcs.anl.gov/~balaji
