Hello, Peter.
I think SSI (Single System Image) does this to some extent: openMosix,
for example, does not have a 'head' node in the sense of a centralised
shcheduler and Kerrighed is similar. What both these systems have is a
notion of the 'home' node where a job originates. Kerrighed can also use
an openMosix-based scheduler. If you're interested, take a look at:
http://www.kerrighed.org
This is an active project - The openMosix project closed two years ago,
and MOSIX2 is a commercial product. Apart from the fact that MOSIX2 is
not open source, it looks very good. However, Kerrighed has some other
interesting and potentially very useful features such as the ability to
aggregate the distributed memory in a way that conventional (non-MPI)
programs can access. Kerrighed also uses quite an efficient TIPC-based
inter-kernel communication protocol.
I'm now using 32-bit Kerrghed, but it's not really stable enough for a
production environment, and most of the Kerrighed development work is
being done on the 64-bit version. So, I've retired most of our 32-bit
kit now and we will soon be running a 64-bit Kerrighed Beowulf :-)
Bye,
Tony.
