FFMK: A Fast and Fault-Tolerant Microkernel-Based Operating System Design for Excascale Computing
Hermann Härtig
TU Dresden
Abweichender Raum: INF/1004
Currently, high performance systems are mostly used by splitting them
into fixed-size partitions which are completely owned and operated by
applications. Hardware architecture designs strive to remove the
operating system from the critical path, for example using techniques
such as RDMA and busy waiting for synchronisation. Operating system
functionality is restricted to batch schedulers that load and start
applications and to I/O. Applications take over traditional operating
system functionality such as balancing load over resources.
In Exascale computing, new challenges and opportunities may put an end to
that mode of operation. These developments include applications too
complex and too dynamic to do application-level balancing and hardware
too diverse to maintain an application-level view of a fixed number of
reliable and predictable resources. The talk will discuss some operating
system building blocks and demonstrate how they integrate into a coherent
architecture.
The talk will address a wider audience, i.e., not primarily operating
system experts. I consider this presentation to be the talk required
after a "Forschungsfreisemester". FFMK is a project funded by DFG within
the priority program "Software for Exascale".
