OpenMosix will not migrate programs with multiple threads. A GNAT task (typically) maps to a thread, so more than one task means your program won't migrate. However I understand that GNAT supports another tasking implementation (FSU threads?) where there is just one thread that emulates several threads (I may have this wrong). In which case a program using the FSU threading implementation should be migrateable even if it has multiple tasks. Duncan.
