the best thing is that you need not write special "cluster aware"
programs. openMosix will migrate processes from one system to the other
and balance the overall load on the cluster.
well, i dont know if this is the best thing or worst thing - it can be
considered a feature or a liability. if one is hoping to solve ten
problems on ten machines, sure, openmosix will migrate processes and
balance the load. but if one wants to solve a ten times larger problem
using the ten machines, openmosix will be happy to keep nine machines
idle. one would have to necessarily write a cluster aware program and
forget openmosix. many applications, especially in aero (cfd and fem) tend
to need cluster aware code.

ps: i am just winding up a full semester course titled 'applied cluster
computing'. course content includes networking and communication
technologies, cpu architectures, overview of loose (openmosix) and
tight(mpi, pvm) clusters and applications to coarse and fine grained
problems. maybe, i can offer this course after i return to iitm campus.
