Subject: Re: [mythtv] clone_vm
As others have mentioned, MythTV uses threads, and openmosix can't migrate threaded applications. A quick google turns up openssi, which is substantially different from openmosix (it's still clustering a set of computers, but it presents them to applications as a single multiprocessor computer), and is capable of migrating threaded applications.
I'm still not sure this is a hot idea, though - if capture is being done on one system (the one with the card), and compression on another (because mythbackend got migrated off of the system with the card), isn't openssi going to be passing the uncompressed frames over your network?
Assuming you're capturing 1GB of raw data a minute, it would be fine on a gigabit network though wouldn't it? (roughly 17MB/sec)

do you guys use it to share memory? or for programs to communaite? i would
really like to disable it so that processes could move around my cluster. if
it is for communation then i know its not gonna happen, but if you use it to
same memory then i can deal with memory sucking processes.
