If we detect what the local architecture is, how will we communicate it to other processes without having some infrastructure that is hetergeneous-architecture safe? — Pavan On Jan 1, 2014, at 9:50 AM, Jeff Hammond <[email protected]> wrote:

One wonders if MPICH could verify the system was sufficiently homogeneous to function properly during initialization rather than defer detection to an error during communication calls.

Are matze-debian and notebook of the same architecture (x86_64 and running the same OS/configuration)?

No, notebook is x86_32 on debian stable and matze-debian is x86_64 on debian testing, but I compiled the program for each system separately.

Such heterogeneous configurations are not supported in mpich.

Ok, thats the problem then. I didn't find that information in the FAQ or in the installation manual.

Thanks for your help. Matthias _______________________________________________ discuss mailing list [email protected] To manage subscription options or unsubscribe: https://lists.mpich.org/mailman/listinfo/discuss
