Im using a config file that came with the MPI2007 image. Why isn it working?
The config subdirectory contains config files that were valid at the time the MPI2007 directory tree was packaged for delivery. There is one config file for each platform that MPI2007 was tested on. These are meant to serve as examples of use on each platform and are used for testing builds of the MPI2007. Even if you are using the same series of compiler and/or OS as the config file in the directory, these components may have evolved since the config file was written, and portability settings in the config file may no longer be necessary so the config file cannot be used to make a valid submission. Even if all the portability settings are correct for your system, it is likely that the choice of optimization settings will not be ideal for your system.
