I think Ralph was asking "where is this value used?" This particular value is one of the constants defined in mpi.h, and it's used in some of the public MPI data structures (the length of some strings returned by MPI to the application). On May 27, 2009, at 8:40 PM, George Bosilca wrote:

No there is no such constraint. Rainer's commit only changed the hardcoded value to another define, which this time can be set by the user at configure time. However, the default value is exactly the same as before (for MPI hostnames is set to 256). george. On May 27, 2009, at 20:02 , Ra

I can't find that max hostname constraint in the above commit (probably just tired eyes). However, note that ORTE doesn't have any hostname length constraint, so if we are now adding one to the OMPI layer, we have a problem. For example, in the ompi_proc_t struct, we simply point it at the ORTE na

One thing to note about this change is that it will break binary compatibility between 1.3/1.4 and the 1.5/1.6 series (since these values are #define's, and therefore are resolved at compile time -- not run-time). While I agree that reducing the memory footprint is a good thing, do we wan
