Remove all architecture references from ORTE and put them back in the modex using modex_send/recv calls. Hetero operations are now fully supported again. Comm_spawn now works up to the point where it segfaults due to an error in the CID code - which now allows Edgar to dig further! :-) This commit was SVN r21655.
