Hello
Has somebody any experiences made with multitasking on openMosix clusters?
Do Ada tasks migrate?
Thanks for any hint.
Roger

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.
