Hadoop is the de facto engine that drives current cloud computing practice. Current Hadoop architecture suffers from single point of failure problems: its job management lacks of fault tolerance. If a job management fails, even if its tasks remains still active on cloud nodes, this job loses all state information and has to restart from scratch. In this work, we propose a distributed MapReduce engine...
Load balanced Birkhoff-von Neumann switches are known to be more scalable than other existing switch architectures that guarantee 100% throughput. However, there are still several design and implementation challenges in prototyping such a switch, including (i) modular design, (ii) synchronization and propagation delay, (iii) fault tolerance, and (iv) buffer management. In this paper, we address these...
